Meter2 for H3 / or integrtion T-series

[Kyterion]

Is there a possibility for the H3 series to read out a generic inverter or, for example, a T series that is connected to the Meter2 interface to read out the power. In the modbus protocol I saw that the adress 31051 exists as Meter2, but I don't find it as an entity. I'm an amateur and a beginner :-)

Yes if meter2 is connected you should find it as sensor.ct2_meter but it will probably be disabled by default (to reduce unnecessary polling)

If you got to Settings, Devices & Services, Foxess - Modbus and click on the ‘1 Device’ at the bottom of the sensor list it will say ‘+xx entities not shown’ - click on the CT2 meter entity, click the cog in top right corner and slide ‘Enabled’ to on - click update.

After a short while you should now see the CT2 meter entity

Thank you for the information. However, I've checked the sensor list, and there's no "+xx entities not shown" option at the bottom. Hence, I'm unable to locate the CT2 meter entity to enable it. Is there an alternative method to activate it?

[FozzieUK]

I have checked the various protocol documents and for the H3 the registers for meter2 do not appear to be exposed over modbus - where did you see address 31051 listed ?

Found it here, but I'm not sure if this also applies to the H3:
KH_KA.Modbus.V1.01.00.2023070801.for.EMS.pdf

The KH is quite different to the H3 I'm afraid

This isn’t the perfect solution, but in the absence of registers for the 2nd meter - you can install the Fox openapi cloud integration which does expose meter2power as one of the entities.

It’s only sampled every 5 minutes (the dataloggers update interval) but at least you will be able to track it and sum it reasonably accurately.

Thank you very much, that will help for now until something happens
