It's definitely not a good thing that invertors require a small amount of energy from the grid. Here in Germany, we buy energy at 30 cents and sell it at a fixed price of 8.6 cents.

Seems it is issue between HA<----->ESPHome communication. Raw data in ESPHome is correct for Total too. Example: [09:22:03][D][modbus_controller.sensor:025]: Sensor new state: 5137.00 [09:22:03][D][sensor:093]: 'Battery Charge total': Sending state 513.70001 kWh with 1 decimals of accuracy [09:22:03 ...

If anyone's had the same problem. Since yesterday the daily and total values are not displayed correctly in HA. Momentary values are correct. As example : h3web Battery Discharge daily 5,435.5 kWh h3web Feed-in daily 6,534.3 kWh Raw data from ESPHome are correct. Example: [09:22:03][D][modbus ...

Hi !
I have very simple integration based on ESP8266 :
https://github.com/mypi-home/HA-ESPHome ... ter-Modbus
I have to change just script from H1 to H3. It is working fine. The device is placed in a DIN rail case. After debugging I will install it to the Electrical Control Panel.

Seems you are right and I have mistake in decoding of Load figures.
I will double check again.

Hi All ! can anyone explain the physical meaning of the raw data ? Meter powerR 31026 Meter powerS 31027 Meter powerT 31028 Load powerR 31029 Load powerS 31030 Load powerT 31031 I think I understand how Meter shows this. Positive figures are Feed-In, negative figures are grid consumption, but I can ...

Hi All ! Modbus error function code: 0x83 exception: 2 It seems that I have a communication via UART, but the response is wrong. What can be the reason for this? I have made the issue here and attached log and config. https://github.com/mypi-home/HA-ESPHome-FOXESS-Inverter-Modbus/issues/1 P.S. Issue ...

Hi Dave! Thank you very much for your answer. The inverter is running without any errors in the log. The battery is attached, and the state of charge is at 13-14% (the settings specify a minimum of 15% on the grid and 10% without the grid). There are no limits for export, and during this time, the ...

Hi All ! As everyone has known since school : PVPower = PVVolt x PVCurrent Now let's take a look at the chart. I have 20 panels, but the strings connections were not made identically. Why at high enough voltage from solar panels, the current is still 0, and therefore the power is also 0 ? Is the ...

Hi All ! I am going to connect adapter with twisted pair cable. Before I started to disassemble H3 connector, would be good to understand how to fix the wire in the socket ? How should the end of the wire be prepared ? Thanks in advance for the help. P.S. If anyone is interested, I'm going to ...

Thank you very much for the explanation. I also took the measurements directly from the inverter. See the attached picture.
Of course the amount is very small, but it is there.

HI all !
I find strange behavior of my installation. The installation does a short power export several times a day, with the battery only 15-20% charged. See attached pic. Can anyone explain this behavior ? Thanks in advance.

yes this is a very interesting question, how does this comply with GDPR.

But in this case, you are giving access and have to fully trust this app that it doesn't have a back door to your data.

Hi ! Finally cloud APP shows only 0 for me, but devices are working correctly.

HI All ! I faced the same situation after this morning's update. My inverter is now consistently drawing 150W from the grid at night with the battery at minimum ( 10% ). Update was from 1.56 to 1.71. I have found solution: Factory Reset, after you need just set up safety standard / country code and ...
