Better ($) electric cars are using heat pumps more effectively to heat. This is a bit more than one yard. The production or consumption measurements received by Enlighten are negative. Announcement: Effective October 1, 2023, Enphase API will only support TLS 1.2 and will not accept any applications on older TLS versions, Announcement: The end of life for Enphase API v2 has been extended from August 15, 2022 to September 30, 2023 0000048897 00000 n I have assumed it was 'Voltage and Current Metering' using the ohm's law variables (P = EI), so EIM. https://github.com/dlmcpaul/EnphaseCollector. Some batteries havent charged or discharged recently. Envoy production.json eim only shows an aggregated number. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 25 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> measure resistance from black wire at lgm connector (while disconnected) to ground behind side panel inside rear cargo area. 1 0 obj Prefix multipliers based on powers of 10 are used to convert meters to other SI units. Example: It is possible to request a subset of the systems list. Attributes that are times are named accordingly (e.g., operational_at, last_report_at, start_at, end_at). My consumption only power-factor when I look at it from the installer toolkit says around 1.0, but the apparent power is nearly double the watt measurement which implies a pf of around 0.5. Part number: 800-00554-r03, Under some conditions, data for a given period may be temporarily unavailable. These come from mainly 3 pages (excluding Envoy running <3.9 firmware), I would propose removing the original consumption parameters and adding additional parameters (lets prepend them in this example with metered_*. So as it stands is your original bug of Production values displaying zero fixed? @rct If you have code changes could you post it to GitHub for a possible merge? 0000012600 00000 n 1 m is about 39.37 inches. If the message persists and is not due to unusual production or consumption conditions, contact your installer for help. avh]O(ar /I;}z*',)RsB$F8$tE)>}0.B "sk]a/E+sQWTM/Na>GGqJRCX?? 0000048727 00000 n The text was updated successfully, but these errors were encountered: @lnlp Would it be possible for you to post a copy of your /production.json? 827 0 obj <> endobj xref 827 81 0000000016 00000 n If you do not want to accept all content types, specify JSON only: Endpoints that receive dates expect the format YYYY-mm-dd. My envoy has been updated twice (or more) as far as I remember. Whether this is actually implemented (case B') when CT's are installed or that only the power input lines (left connector) are used ('case A') for voltage measurement I'm not sure. This page was generated at 03:27 AM. The CTs accommodate conductors up to 4/0 RHW, 350MCM THWN, Since installation the system has shown an intermittent error: "Meter Issue. Meters that have been retired from a system will show an end_at that doesnt change, and that eventually is far away from the current time. 0000012488 00000 n Do not nofollow your links to Enphase. That's why I'm asking to track the above as separate issues. Enlighten declares a Meter Issue () system status when it detects a possible problem with the CT or storage measurements. Question for you or anyone who has CT metering turned on: I believe production.json - production[0].wNow shows the current power from the inverters regardless of whether CT metering is turned on or not. The circuit passing through the consumption CT does not include AC Batteries. I have made the change to fix it, actually just removed a single line of code, PR #51. stream Professional installation is required, please contact your installer for an estimate before purchase. 0000140307 00000 n I does give a way of polling the detailed data from each CT for what looks to be all three phases, whether it is installed or not. When using Envoy S without having CT's enabled then production data in envoy/production.json is NOT updated. Is D5.0.49 newer than R4.10.35? When the query parameters include production=all, returns meter and microinverter-measured time series: Returns a listing of all active Envoys currently deployed on the system. Fyi: There exist 3 different Envoy-S models: I have the Envoy-S Metered Multiphase (EU) SKU: ENV-S-WM-230. Automatic: When CT's are not enabled this is shown on the envoy/home page so it should be possible to automatically scrape the status of whether CT's are enabled or not. Right after connecting the power lines to the grid I already have some statistics of the grid meter (in the Netherlands called the Slimme meter, which you can read through the P1-port using i.e. 0000011718 00000 n If your system is producing less energy than your installer estimated, youll see a message like this: Click Learn more for information on how to get help with the problem. While much of the rest of the world uses the metric system of centimeters, meters, and kilometers, US has continued to the English units. I need to understand how the Home Assistant configuration interface interacts with envoy_reader to configure it. If it continues to display Envoy Failure or if it never moves beyond the Envoy All API requests require your API key and a user_id. Envoy S Production data is not read / read incorrectly when meter_issue One or more meters on the system are reporting unusual period_start and period_end tell you when the minute (in this case) started and when it will end. Note that big power spike in the morning, that is our electric car (Ford C-Max Energi) pre-heating the cabin. EV owner since 2012. Gaps in reporting are not filled with 0-value intervals. 2 0 obj (Maybe you are mistaking with the cloud API's update frequency?). My envoy has values for those rather than all zero, because metering was turned on a while but wasn't giving the right values. 0000093917 00000 n metered_production wNow: 2.79 (gets truncated to 2) Enlighten declares a Meter Issue () system status when it detects a possible problem with the CT or storage measurements. You may filter on the following attributes: system_id, system_name, status, reference, installer, connection_type. This would allow access to finer grained energy production data for uses such as graphing 15 minute intervals. The code is currently returning values for those rather than your 'not available' message. I like the suggestion of using /api/v1/production by default and add the additional metered_* parameters for /production.json. Is that new Envoy firmware? The review process is greater. So I swapped the leads on the Envoy for the consumption CT's and have been monitoring all day and the data looks good. Envoy For /api/v1/production the timestamp can be read from production.json "inverters" section. So to make changes unfortunately we can't add a new sensor and display the new data. There are no gaps in the time series. By default envoy_reader should automatically determine whether CT's are enabled and act accordingly. Envoy You have your consumption meter set to "load with solar production" or "load only"? 0000007176 00000 n If you have subscribed to a plan marked Enphase attribution required, you must meet the following requirements as explained in the Enphase API License Agreement. Now to change how things are displayed in Home Assistant, or adding/removing sensors that means probably both an API side code change as well as the sensor code change on the Home Assistant side. Meter Web//= $_COOKIE['currency'] == 'USD' ? I suggest to add the following two output parameters for this (so they can be read as sensor values in Home Assistant also); Can you open a new issue (enhancement) to track adding new parameters? Well occasionally send you account related emails. CT Measurements" from a consumption CT on one of the phases. If the system doesnt have any microinverters installed, the response includes an empty intervals array. Envoy Are all three phases wired to your Envoy power connector_(most-left connector on the Envoy)_? I hope we can see it being updated in Home Assistant as well soon. If you are not sure how to meet these requirements, please contact api@enphase.com before you launch anything. 0000154881 00000 n @gtdiehl - I think the only cases where you'd want to use /api/v1/production are: I don't have code changes that are worth submitting. Note: my CTs are currently disabled. Enphase Envoy In 'case B' one may wonder why the 'power connector' on the left exists and allows to wire all 3 phases. Yes the original bug in envoy_reader has been fixed. /production.json: "type": "eim", "rmsVoltage": 245.583 Because envoy_reader appears to read them from /production.json where the names are present but their values are 0 and do not get updated. @jesserizzo What do you think about moving all of the production polling to /api/v1/production and only use /production.json for metered production and consumption data? Software Version: R4.10.35 (6ed292) Examples include asking for stats starting at a time that is later than the systems last reported interval, or asking for stats before a system has started production. You may pass a limit parameter to the request, which sets the page size for that request. If the input date range is more than 7 days, the following error will be thrown. All dates are in the timezone of the requested system. Enphase consumption CT measurement problem. - Solar Panels For example, midnight on 5 May, 2015, in Pacific Daylight Time is 1430809200. Unless I'm wrong about that, it would be useful to be able to get wNow (production) for both, so hopefully your naming would also include inverters_production. If the system doesnt have any consumption meters installed, the response includes an empty intervals array. Keeping in mind that consumption monitoring is an optional add on that doesnt interfere with the core functionality of the solar system. If some of your microinverters have stopped reporting to the Envoy, youll see a problem message like this: Click the link in the message to see which microinverters are not reporting and their location in your array: Learn what you can do if some of your microinverters have stopped reporting. Long explanation that I don't think I have any unique problems, just that the mppt curve does not track well below 28% of peak array power. WebEnvoy-S Metered and Envoy-S Metered Multiphase (IQ Envoy) are both black but the Envoy-S Metered Multiphase has the cover screw on the right side while the Envoy-S Here's my output. For a Net metering arrangement (load with solar), the Consumption CT must be positioned to measure the site loads AND all of the solar export. There was a reply in the Home Assistant Community forum where a person took this screenshot. 0000023653 00000 n Better ($) electric cars are using heat pumps more effectively to heat. 0000303640 00000 n Leave it in place for at least 15 minutes. /production.json "type": "inverters", "wNow": 2235 0000033020 00000 n /production.json: "type": "eim", "rmsCurrent": 0.534 And for the nice to have wishlist: Immediately to the left of or above the mark, you must display the words Powered by in a clear and conspicuous manner and in a minimum eight-point font. Enphase seems to have a bug where they sum the amperage values for each phase and then multiply that by 240 to get VA. That's wrong and results in a VA value for TOTAL CONSUMPTION that's upwards of twice what it should be. WebThe LEDs on the Envoy-S are solid green when a function is enabled or performing as expected, flashing when an operation is in progress, or solid amber when To enable correct operation of the Enphase Home Energy system components (including the Enphase AC Batteries), the Envoy must correctly measure the current flow across the electrical circuits via the CTs. For the best experience on our site, be sure to turn on Javascript in your browser. EDIT: I actually just found a setup like this. Key Points read_at is the time at which the reading was taken, and is always less than or equal to the requested end_at. @OllemGit In addition, the Envoy-S Metered provides revenue-grade production data and allows for the monitoring of a sites energy load, thus offering significant advantages over other PV system monitoring equipment. Users can access energy production and consumption data through Enphase Enlighten cloud based monitoring software. When I mean fully is that if something can be fixed on the Api side, such as the original bug of the Production values being zero than I can make a change here and request Home Assistant through a PR to update the version of the API being used. The time series includes one entry for each day from the start_date to the end_date. Here are captures of /api/v1/production, /production.json and /api/v1/production/inverters. There is an issue with your envoy meter measuremen Last one. When I investigate the raw numbers from interrogating the envoy direcly it actually shows me the low power factor. Note that big power spike in the morning, that is our electric car (Ford C-Max Energi) pre-heating the cabin. This is the output: The inverters and the CTs dont report the same values and Envoy reader can make an incorrect assumption about whether CT metering is being used. 0000078331 00000 n How NASA Lost a Spacecraft From a Metric Math Mistake When they can finally talk it tells the Envoy this and the system averages it I'm not sure on this one. See Andrew Mitchell's Enlighten Manager Mastery video for a visual walkthrough of CT troubleshooting using Enlighten Manager. In progress - Scheduled maintenance is currently in progress. I've tried switching polarity on the CTs, and moving them around, but I can't get it into a real range. Here is heavy overcast at the end of the day with sun low and far to the side of the array. When fixing wires and connections, aim for a 0000016703 00000 n The new version of API (v4) is available at: developer-v4.enphase.com. Thanks for your continuing efforts! But envoy_reader does not read it. I therefore did not install any CT's. trailer <]/Prev 1017858/XRefStm 2698>> startxref 0 %%EOF 907 0 obj <>stream ct_enabled with default value True (requires no changes in existing client code). If there is an issue with the Envoy meter measurements, youll see a message like this: If one or more of your AC Batteries hasnt charged or discharged for the last 72 hours, youll see a message like this: This may not indicate a problem, especially if there hasnt been enough sunshine to produce energy that exceeds your homes consumption, or if your homes energy use has gone down to the point that the batteries dont need to discharge. Like I said I haven't looked through all of the comments yet. The next screenshot shows the cumulative effect of the negative reading on the lifetime measurements; Screen Shot 2019-01-04 at 10.24.51 PM.png, Solar Panels for your Home, Grid Tied Solar PV, Screen Shot 2019-01-04 at 10.24.59 PM.png, Screen Shot 2019-01-04 at 10.22.19 PM.png, Screen Shot 2019-01-04 at 10.26.09 PM.png, Screen Shot 2019-01-04 at 11.25.06 PM.png, https://enphase.com/sites/default/finvoy-EN-US.pdf, https://thecomputerperson.wordpress.com/2018/08/18/what-is-inside-the-enphase-envoy-s-teardown/, https://www.solarpaneltalk.com/filed7&d=1546658760. meter types, electrical connections) can vary across Australia. I don't really understand how the system is configured. In 'case A' one may wonder why the phase voltages are reported separately for production, net-consumption and total-consumption. In general, a Meter Issue indicates a system where on-site maintenance may be required. 0000232378 00000 n WebThe use of any other type of CT will result in incorrect power measurements, and may permanently damage the WattNode meter. This is because envoy_reader assumes that when `envoy/production.json' exists that this is the location to read the Production data from. Interesting, /ivp/meters gives some configuration/status information such as phaseCount and phaseMode that I haven't seen elsewhere: http://envoy.local/ivp/meters/readings seems to be very useful. At first I seemed to get a 404 for but maybe I didn't get the plurals right though http://envoy.local/ivp/meters/readings. If you are upgrading with Enphase microinverters to an existing string inverter installation, follow one of these options: All solar AC cables must pass through the Production CT. 0000010160 00000 n When this parameter is provided, the returned JSON is wrapped in the callback. From this perspective it is not required to connect all 3 phases to the power connector. The time series includes one entry for each day from the start_date to the end_date. All measurements are in Watt hours. 0000016000 00000 n issue with envoy meter measurements Regarding bullet 2: No, not only those two values. "[}QXD/jD NCrncVa @L*23m It does show in the HTML output, but scraping should be avoided. I use Envoy S but without any CT's installed. Thank you for opening those issues. Clients of the API are expected to do the same: Be order-agnostic, and ignore unknown response values. Sign in My Envoy IQ is running D5.0.49 (77afa8) Build date Thu Mar 19, 2020 01:44 AM PDT. Enphase CT Consumption Measurements Error - Solar PV What does the "Envoy Failure" message mean? - Enphase Support 0000010645 00000 n rmU)dC!.d0oQmLL"xoCFDLLBJoFI%g%(1S0i/(yv65^S)^*By[(& arHB~*UA{Tjj!W6 $I(7dwA_ A}Tb|X_7)gk:}tD@}Xk/Vsm4'gJO~* EHRv91X Q8^@DagKqOfL`mSJ4U=TB\o/)u{xYK5_Kmx~.s !3hUtI WpeWJ`+qQ| i%YlbrC3 v.PWBUfMI3OfL I have read through everything yet but I want to point out that when polling uses the /api/v1/production page the envoy appears to only update it every 15mins. trouble with enphase envoy consumption measurements Enphase Handy Tips - Wiring your CTs for Gross vs Net Metering The Envoy backend should actually have both values, and the API retrieving the data You can sign up to be notified by email if your system experiences either type of production issue. Andrew Mitchell's Enlighten Manager Mastery video. Anyway, I tried reversing both the production CTs and swapping their phases. 0000339432 00000 n @rct the scraping blog was where I got that URL. WebAN_6612_032 Energy Measurement in Split Phase Systems Using 78M6612 Rev. All rights reserved. Note: If a system does not include a given device type, that key is left out of the returned hash. I know not a perfect solution but through small changes eventually we will get to a release that meets the needs of Envoy users across all firmwares . In general, a Meter Issue indicates a system where on rmsCurrent and rmsVoltage if only single instances reported for these instead of separately per phase? envoy_reader should handle all these (4) situations correctly. D`TR2 (P@$D j+C"qa7%A]4(uWP7T! 0000110513 00000 n See following comment in #46 for more information. This has to either be an issue with where the consumption ct clamp has been installed, its orientation (arrow direction) or with a software setting on the envoy or a combination of all 3 possible causes. )bJ60F-phEZ As a result the reported Production values are either 0 or some bogus value. 3 0 obj I would like some input from @jesserizzo and others before opening a PR to merge this change. The Enlighten Systems API There is an issue with the meter measurements. This status was for me while debugging. Learn what you can do if the systems meter has stopped reporting. I see where you are coming from but to keep the code simple I'm retrieving inverter production values from /api/v1/production rather than pulling a value from /production.json and the rest from /api/v1/production. If the consumption measurements received by Enlighten do not appear to include storage activity, there are two possible wiring issues that can cause this: The Meter Issue status will continue to display until Enlighten receives 24 hours of meter measurements that indicate the problem has been addressed. I believe there should be the option to get either or both production wNow values for the inverters and the eim (CT) structures. No Home Assistant will not get fully updated automatically. I'm thinking maybe another check of the attribute eim. Other than reducing http calls to the envoy device, is there another benefit to pull the production data from the two pages rather than one? I removed the inverter data and right now the values are zero due to no sunlight, but you should get an idea of what would be sent to Home Assistant once that sensor code is updated. Regarding measurements for each phase, he Envoy has a URL that deliveries a stream of measurements -. This is called the merged time series. In addition, the response includes the attribute meter_start_date, to indicate where in the time series the meter measurements begin to be used. 0000128068 00000 n Exactly: I have only CT's installed for measuring Consumption "CT's" is plural but consumption/eim/activeCount only shows 1. 0000014311 00000 n So I swapped the leads on the Envoy for the consumption CT's and have been monitoring all day and the data looks good. There isn't any identifying object info inside the two objects in the top-level list. WebMake sure to keep your meter lead wires away from engine moving parts during this test. m%=747:5e}b6K8W]WQqLLOm+..^l,b09#Sx"Urk`d/2Qo1)I:wsKakSfj+C h`JqYYYvXg/._nl(E,o@8;"9JXq51)j|*)1\.ipYR?g/_1k'J1jO. For example, a request for 08:01, 08:08, 08:11, or 08:14 is treated as a request for 08:00. Already on GitHub? Metering requirements (i.e. So I just display the values unless the device actually does not support metering. /api/v1/production, Here is my current http://envoy.local/api/v1/production. @gtdiehl Here is my current production.json from my IQ D5.0.49 (77afa8) with CT metering turned off. The PF of the. WebThe Envoy-S monitors the microinverters that are connected to the PV modules. Got your message a little before 11am my time so low production is just winding down. If the total duration requested is more than one day, returns one day of intervals. 0000032874 00000 n Perhaps for compatibility there should be three available entities for the wNow values in Home Assistant: Having these three elements would allow the user to override Envoy reader's choice if necessary as well as track both on systems with CTs if the user chooses that. My /api/v1/production/inverters inverter data is already properly read and output by envoy_reader (I can see the values in Home Assistant). Webmeter There is a communication problem between an Envoy and a revenue-grade meter on the system. Energy Measurement in Split-Phase Systems Using Returns consumption as measured by the consumption meter installed on the specified system. I've connected them using Enpase IQ7+ micro inverters and bought also a Envoy-S Metered with them to read out the production statistics. You signed in with another tab or window. I currently check the /api/v1/production data in a browser and refresh manually. Enphase Solar PV Installation Certification Training Flashcards All rights reserved. Currently I do not have TOU rate pricing. Not sure what the actual url for the page is though. I'm not sure what would be a good way to name production Watts data elements to allow referencing either or both of them in Home Assistant's configuration. Enphase consumption CT measurement problem. The CT direction arrow of each CT, in a Net metering (load with solar) configuration, will always face towards the load circuits of the site. It appears that this value is probably taken from the same L1 input, but its value differs few-thousand's of a volt. ^nBsEi. The epoch format returns all temporal values in Unix epoch time. It only reads envoy/production.json. 0000139340 00000 n The circuit passing through the consumption CT does not include AC Batteries. That may be a clue. Yes, I do want and think the values for both inverters and eim should be accessible if available. I was happy to see it working in 2020.12.0 now but then noticed values reported in HA don't match /api/v1/production. /api/v1/production does not contain "readingTime" but /production.json "type": "inverters" does. Also would need to check this behavior on newer firmware such as D5.0.49 (77afa8) to see what happens when metering is not setup and if the /production.json page returns valid data or not. Intervals are listed by their end dates; therefore, the first interval returned is 5 minutes after the requested start date.
