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. This status was for me while debugging. If the answer to the above question is true, then it would also be useful to have inverter_lifetime_production in addition to metered_lifetime_production. The code is on one of my branches. I have not done the math to calculate the cost savings for such a small battery (10 kWh) on the Ford. If Enphase has detected a possible hardware issue that may be affecting system production, youll see a message like this: Click the link in the message to see which microinverters are reporting a production issue and find out how to get help with the problem. Planning and installing consumption monitoring 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. WIRING EXAMPLE:Envoy S Wiring recommendation Subboard Typical 1Phase Net Metering, WIRING EXAMPLE:Envoy S Wiring NSW METERING recommendation 1Phase TWO METERS for Net Metering. 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 CT direction arrow of each CT, in a Net metering (load with solar) configuration, will always face towards the load circuits of the site. I would expect to see at least three different sets of values, one for each phase. Could there there be another (URL) location on the Envoy where differentiated data for each phase is available? In general, a Meter Issue indicates a system where on-site maintenance may be required. The production or consumption measurements received by the Enphase Cloud are negative. If the system has both production and consumption CTs installed, you can see which meter is affected by checking the meter status on the Devices screen. Contact us for sales, quantity discounts and expert reviews for the Enphase CT current transformer for Envoy. 0000003055 00000 n If so this may end up being the best solution, although it requires 2 requests. 0000001916 00000 n I believe there should be the option to get either or both production wNow values for the inverters and the eim (CT) structures. This means that we need separate 'CT Metering' parameters for production and for consumption. Clients of the API are expected to do the same: Be order-agnostic, and ignore unknown response values. 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. meter_issue One or more meters on the system are reporting unusual For /api/v1/production the timestamp can be read from production.json "inverters" section. @atTD+JNE\:R @rct If you have code changes could you post it to GitHub for a possible merge? I therefore did not install any CT's. 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. (I have observed bogus values for 'production' and 'consumption' in range between 0 and 2). Enphase Handy Tips - Wiring your CTs for Gross vs Net Metering @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. Enphase consumption CT measurement problem. It collects energy and performance data from the microinverters over on-site AC power lines, and it forwards that data to Enlighten, via the Internet, for statistical reporting. I would have to look into how to send specific data from the envoy_reader API to Home Assistant. /production.json "type": "inverters", "wNow": 2235 EV owner since 2012. Copyright 2014 SolarReviews All rights reserved. Or maybe the Envoy combines the data of all three phases and the differentiation gets lost? The circuit passing through the consumption CT does not include AC Batteries. The production or consumption measurements received by Enlighten are negative. 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. @lnlp Thank you for running the code!

Envoy 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 WebTo enable correct operation of the Enphase Home Energy system components (including the Enphase AC Batteries), the Envoy must correctly measure the current flow across I have it set on load with solar production. I hope we can see it being updated in Home Assistant as well soon. I would like some input from @jesserizzo and others. Prefix multipliers based on powers of 10 are used to convert meters to other SI units. Solar Production CT MUST measure all solar circuits on site. So I've had my envoy setup for 5 years now no issues. The circuit passing through the production CT includes AC Batteries. 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. I agree a better solution would be to have additional parameters.

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? The rationale is so that the Home Assistant sensor monitored_conditions does not have to change which ultimately does not create a breaking change or force users to change their environment. Some may view this as a draw back. IF you require further technical clarification for your installationplease contact Enphase Technical Support. I 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. I just wanted to let you know the logic might not be working as intended. Intervals are listed by their end dates; therefore, the first interval returned is 5 minutes after the requested start date. Observation: metered values get truncated instead of rounded. => 4 wires enter the most-left connector of the Envoy + 3x2 wires for the CT's All rights reserved. For more details, visit 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?

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? (*) Note: I don't know that production[0].type is always inverters and production[1].type is always eim. 1.0 5 Additional Features Additional features include wrong wiring detection, such as inversion My /api/v1/production/inverters inverter data is already properly read and output by envoy_reader (I can see the values in Home Assistant). period_start and period_end tell you when the minute (in this case) started and when it will end. WebThe split-core consumption CTs open and clamp around an existing conductor or busbar without rewiring. Are all three phases wired to your Envoy power connector_(most-left connector on the Envoy)_? Like I said I'm still thinking about it and weighing the pros and cons. The darkish overcast looked like possible little snow storm coming. Do not nofollow your links to Enphase. Returns the energy production of the system for the month starting on the given date. Sign in Currently to minimize api calls between the envoy and home assistant one function is called to gather up all the data (even if the device does not support the parameter) and send it across. All were taken at the same time. 0000023514 00000 n But that is an incorrect assumption because it is only valid when current transformers (CT) are enabled/installed. tvd`x]6d=WY fj0A2!

In 'case A' one may wonder why the phase voltages are reported separately for production, net-consumption and total-consumption. Have you tried flipping the CTs 180 degrees? While much of the rest of the world uses the metric system of centimeters, meters, and kilometers, US has continued to the English units. Your message explains this. 0000232417 00000 n To troubleshoot this, check CT orientation and leads, compared with voltage measurements using your regional CT Maybe this is only of interest to me. 2 0 obj WebThe use of any other type of CT will result in incorrect power measurements, and may permanently damage the WattNode meter. This is just low sun with overcast far to the side of the array. Maybe I should have been a little clearer but Home Assistant is not letting existing integrations to change their monitored_conditions. It appears that this value is probably taken from the same L1 input, but its value differs few-thousand's of a volt. Do you expect to get the fix into the next (bug-fix) release (presumably 2020.12.1)? Good catch! All times are GMT-5. 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. 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. I discovered that /production.json can also provide per-phase values. Do not violate the other restrictions described in the Enphase, Copyright 2023 Enphase Energy, Inc. All rights reserved. Intervals are 5 minutes in length and start at the top of the hour. 2002 Envoy Electrical Issues Related to Liftgate When the Envoy and the microinverters cannot talk for extended periods of time the microinverters try to hold a basic record of I produced x much power from x date to x date. If you dont have permission to view consumption data, the response code is 401. The installers could have put it on the wrong leg. My Envoy IQ is running D5.0.49 (77afa8) Build date Thu Mar 19, 2020 01:44 AM PDT. Meter Connecting only a single phase to the 'power input' connector (instead of all 3) already makes the system work (but will cause some values to be reported incorrectly). Attributes that are dates are named accordingly (e.g., summary_date, start_date, end_date). 0000196625 00000 n Correct me if I'm wrong, without CT metering, Also, If state was kept and easily accessible in either envoy_reader (or Home Assistant), today's WH production and the last seven days of WH production could be determined from tracking the, If CT metering isn't turned on, and the user wants to see the Envoy's inverter totals for today and the last seven days, then. Professional installation is required, please contact your installer for an estimate before purchase. Observation: metered values get truncated instead of rounded. 0000078062 00000 n 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. That's why I'm asking to track the above as separate issues. Attributes that are times are named accordingly (e.g., operational_at, last_report_at, start_at, end_at). The heating system is just resistance heaters on that car so it's like a giant toaster oven. Or maybe the Envoy combines the data of all three phases and the differentiation gets lost? 0000452724 00000 n For example, if your API key is 123ABC and you are making a request for user_id 4d6a51330a, your requests would look like the following: To learn more about user_ids, see the Quick Start page. Hopefully that data can be read from elsewhere on the Envoy, without requiring installer permissions. According to the IQ Envoy manual this is possible if the user wants revenue-grade production metering. metered_production_readingtime Envoy I've got the old (non-IQ) version of the envoy. And possibly add another parameter called activeCTCount to tell the user if the Metering feature is enabled on their Envoy? My blue bars show production and yours appear to show consumption. This is because envoy_reader assumes that when `envoy/production.json' exists that this is the location to read the Production data from. Sometimes a request cannot be processed because the requested dates are invalid for the the system in question. Any link back to Enphase should be follow-able. Learn what you can do if the systems meter has stopped reporting. I use Envoy S but without any CT's installed. I know this may seem like a back step but I'm thinking of changing back to the original output of the envoy_reader api, and have the code get the production values based on the activeCount attribute. Can you confirm that you can get this without any authentication? 0000010645 00000 n This is a bit more than one yard. It appears to work fine. Test a Crankshaft Position Sensor Using a Or atleast get reporting working for all attributes for each hardware platform. 0000093917 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. I have a 3 phase power system, so I also have 3 CT's which each measure 1 fase, but in the Ephase app the value is shown as a single Power consumption parameter. I am just grasping at straws here. |JU\"K2b Where's the Leak? Servicing Today's Cooling Systems | MOTOR Enlighten declares a Meter Issue () system status when it detects a possible problem with the CT or storage measurements. Note: I've got production and consumption metering turned off (activeCount == 0). 0000007176 00000 n If a meter or meters are installed on the system, measurements come from the meter; otherwise, measurements come from the microinverters. And for the nice to have wishlist: A device is considered active if it has not been retired in Enlighten. I'm sorry about this! Imagine that the initial ammeter reading, captured on the 10A scale, was .365A (365mA).
