H3-Smart - unknown entity for Total PV
Hi all,
Thanks to the support of the community, I was able to setup my new H3-10.0-Smart inverter in Homeassistant. Connection is made via Elfin EW11a RS485Modbus.

I had to use a pre-release version of the FoxESS modbus integration because the current release version was not populating any entity with data at all.

All entities / registers seem to work except the one for „PV Power“ - which presumably should be the entity for combined solar power of all MPPTS.
Is there any fix for this?

HA: 2025.10.1
inverter Manager version: 1.09
FOxESS Modbus Version: 14.0b3

Thanks and Cheers!

Do a full restart on your home assistant, PV Power is a combined integral sensor but occasionally it hangs when first created, once there is a couple of hours of data it should be populated after a restart.

Hi Dave,

Many thanks. That’s great. Full Restart solved this issue - now I have all relevant entities populated.
