Hello everyone, I have the H1 3.7 inverter with the EP5, and I have too, old panels with microinverters that appear in the fox mobile app as GEN LOAD. My quaestion is how I can sum the power generator by GEN LOAD with the normal PV to obtain the real solar generation. The app only give me the stats of PV. Thank you

Sadly you can’t with the app, it only provides statistics for what the hybrid inverter generates and only shows your second inverter in the graph traces (it needs to know what the other inverter is generating or the load calculation will be wrong).

If you set up a home assistant (you don’t need a modbus adaptor, you can connect to the Fox cloud via openapi), with this it is possible to generate statistics for entire household power generation,

Thank you for the replay. I like to have it on app too but ok... and yes I have home assistant, but I don´t know yet how to have an entity with KWh I only have a CT2 that give me Watts, Ican´t trasform it in KWh by day.... week etc

In HA click on Settings, Devices & Services, Helpers, Create Helper, choose ‘Integral Sensor’,

Give it a name ‘My CT2’, metric prefix ‘k’, time unit ‘Hours’, in the entity box enter the name of your CT/meter2 power sensor, choose ‘Left Riemann sum’, Precision ‘2’ and leave max sub interval alone and click Submit.

That will create a new sensor that is the riemann sum of your CT2 power sensor, which converts it from ‘kW’ to ‘kWh’ and it will be a running total for all power through that sensor.

It will take an hour or so to collect data before it shows properly, but once it is ready you can then add it to your Energy Dashboard as is, or if you want daily, weekly totals you can repeat the process but instead of ‘Integral Sensor’ choose ‘Utility Meter’ , give it a name ‘My CT2 Daily’ select the entity you have just created, Meter Reset Cycle ‘Daily’, then click Submit. - that will give you a daily CT2 energy total.

I create the myct2 but the value returns "0", when I click on the new sensor in helpers menu. In the energy dashboard settings I can´t add the new sensor because it doesn´t appear in the "add". Can you help me? thank you

Can you click on the new sensor and screen shot that page, or alternatively in the dialogue that shows the entity value of 0.00, what is the unit reported as is it ‘kwh’ or something else ?

Ahh I just tried on my system and see where it would have gone wrong, I shouldn’t have specified ‘k’ in the metric prefix as the sensor is already in ‘kw’, that would have created a ‘kkwh’ sensor - no wonder it stayed at zero.

Can you click on the sensor your created and delete it.

Then repeat what I said above i.e. click on Settings, Devices & Services, Helpers, Create Helper, choose ‘Integral Sensor’,

Give it a name ‘My CT2’, leave metric prefix blank, time unit ‘Hours’, in the entity box enter the name of your CT/meter2 power sensor, choose ‘Left Riemann sum’, Precision ‘2’ and leave max sub interval alone and click Submit.

That should now work and after receiving a few data samples should become a statistic that you can add to your energy dashboard.

BINGO!! Thank you!!! yes it was the "kkwh" I correct it like you said and already pass one day and it´s counting. After 10 months of many chatGPT with many code in yaml, you with 2 posts resolve my issue . Now I will try the daily, month and year values to put in a graph. Thank´s!!
