I just wonder is there a configuration of the Envoy where a production CT is installed without a consumption CT? My /api/v1/production/inverters inverter data is already properly read and output by envoy_reader (I can see the values in Home Assistant). 0000017430 00000 n 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. Do not violate the other restrictions described in the Enphase, Copyright 2023 Enphase Energy, Inc. All rights reserved. production_readingtime (source: production.json production inverters readingTime) Specifically it has to do with the power factor. By default, systems are returned in batches of 100. This "readingTime" is probably accurate enough to be used as timestamp for data in /api/v1/production. I wonder if they can tweek low light efficiency for me? Hopefully that data can be read from elsewhere on the Envoy, without requiring installer permissions. 0000154881 00000 n But have to think about current users. This endpoint can return a response of Data Temporarily Unavailable. On the MyEnlighten desktop application, the icon to the left of your system name tells you how your system is doing. In my comments above, I was arguing for the case to still be able to get the inverter numbers even if metering is enabled. 9 kW solar, 42kWh LFP storage. I have tested your latest envoy_reader.py. A difference of 1 Watt, which may be caused by a rounding error, or by a small difference in moments of measurement. Enphase CT Consumption Measurements Error - Solar PV If there is a problem, MyEnlighten and the Enlighten mobile app show a message to help you know what to do next. You can retrieve the complete time series from the meter and from the microinverters by adding the parameter production=all to the request. So I swapped the leads on the Envoy for the consumption CT's and have been monitoring all day and the data looks good. The installers could have put it on the wrong leg. If there's voltage over 0.2 volts in any wire or connection, check for corroded, damaged or loose wires. The Envoy can accept 2 x CTs paralleled into the same CT terminal. All rights reserved. Here are the possible messages that may be displayed: Some microinverters have stopped reporting. If you do not want to accept all content types, specify JSON only: Endpoints that receive dates expect the format YYYY-mm-dd. There are no gaps in the time series. Data coming from /api/v1/* is updated every 5 minutes. Sign in It only reads envoy/production.json. @atTD+JNE\:R When current transformers (CTs) are wrapped around a live 0000020597 00000 n Highly configurable 127v VRef, 60hz profile intended as a source for custom profile derivation, including Advanced Grid Functions. 0000452724 00000 n In metric, 1 meter is 100 centimeters and a kilometer is 1000 meters.

Requests for times that do not fall on the 15-minute marks are rounded down. If these are zero than poll data from the other production page. When using Envoy S without having CT's enabled then production data in envoy/production.json is NOT updated. In general, a Meter Issue indicates a system where on-site maintenance may be required. Envoy-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 Metered has the cover screw on the left side (like Envoy-S Standard). I hope we can see it being updated in Home Assistant as well soon. Current Transformers (CTs) are installed to measure Solar (production) and Home Loads (consumption). Too bad, but no need to feel sorry. Note that the parameter name must include [] after it in order to indicate that it is a multi-valued query parameter. WebThe use of any other type of CT will result in incorrect power measurements, and may permanently damage the WattNode meter. Active does not imply that the device is currently reporting, producing, or measuring energy. Commonly, the reading will be within 30 minutes of the requested end_at; however, larger deltas can occur and do not necessarily mean there is a problem with the meter or the system it is on. 0000012600 00000 n Though this time I had someone add my PR to the list of PRs that should be included in 2020.12.1. When I modify envoy_reader.phy to explicitly set endpoint_type to "P" then the production values are read from /api/v1/production and are displayed properly. Returns the summary along with the energy produced on the system over its lifetime. 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. I'm producing 1-5 kWh/day and I see almost the exact daily amount reducing my consistent 7 kwh daily usage. How do I troubleshoot a Meter Issue system status? | Enphase So far, I haven't seen a flag from the Envoy API that indicates whether it is using the inverter measurements or the CTs, but maybe I haven't looked deeply enough. 0000339432 00000 n For /api/v1/production the timestamp can be read from production.json "inverters" section. The start date must be at least one month ago. The rmsVoltage may actually be measured by the Envoy, but without any CT's installed, the rmsCurrent value apparently is a bogus value(?). Envoy Refer to the Release notes page for any recent changes to the Enlighten API. This requires an alternative arrangement of the CTs for correct measurement. Like I said I'm still thinking about it and weighing the pros and cons. Yes the original bug in envoy_reader has been fixed. In other words, if you explicitly want to access that data for the inverters whether or not metering is on, production[0] is the place to get it. If you dont have permission to view consumption data, the response code is 401. Sometimes, but not I did not check (yet) where the come from and/or lead to, I did not check (yet) where the come from and/or lead to. 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. Have a question about this project? 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. The new version of API (v4) is available at: developer-v4.enphase.com. So to make changes unfortunately we can't add a new sensor and display the new data. This is useful where you need to capture the production data of another PV installation where this is wired to a different location in a property. (latter number is lower but 'R' looks higher/newer than 'D'), Can you please add the following parameters for reading timestamps? Do you expect to get the fix into the next (bug-fix) release (presumably 2020.12.1)? A. Note that big power spike in the morning, that is our electric car (Ford C-Max Energi) pre-heating the cabin. 0000026874 00000 n Remote problem-solving The Envoy lets you pinpoint performance issues instantly and resolve them remotely, before they get in the way of system performance. 3 0 obj My envoy has been updated twice (or more) as far as I remember. If the meters milliamp scale goes up to 500mA, then Do not nofollow your links to Enphase. The code is on one of my branches. Sometimes a request cannot be processed because the requested dates are invalid for the the system in question. So this voltage is apparently read from L1 on the 'power input' connector.

Envoy reader makes an assumption depending on the type of Envoy whether CT metering is being used. I assume a much larger EV is in our near-ish (2-3 year) future and getting TOU will absolutely make sense then. 0000012231 00000 n 0000161348 00000 n Metering requirements (i.e. In the "inverters" section? No Home Assistant will not get fully updated automatically. 0000023514 00000 n What about 3-phase systems? metered_consumption_readingtime, How about simplifying I tried to take a screenshot but it did not come through very well. In that case, the response code is 500 and the response body is. @rct I get what you're saying. I haven't reached out to Enphase yet. The response includes intervals that have been reported for the requested period. 0000196664 00000 n 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. CT metering can be turned off even on newer Envoys if the CTs aren't installed or are installed incorrectly. Key Points Will there be / shouldn't there be 3 separate "eim" sections, each for one phase? You may pass a limit parameter to the request, which sets the page size for that request. Or maybe the Envoy combines the data of all three phases and the differentiation gets lost? Have you tried flipping the CTs 180 degrees? 0000048727 00000 n Some batteries havent charged or discharged recently.
