FoxESS Community - Owners & Installers Forum

Apologies if this has been asked endlessly - I have searched but I'm not 100% clear.

the above table is helpful but its not clear how to use the supported features to me.
My desire is to use Home assistant to change the mode of my KH8 Inverter - mostly just between force charge, force discharge and self use and adjust MinSoC values where appropriate.

My KH8 has a wireless dongle plugged into its USB port. It has an ethernet port on the bottom. Currently it's connected to FoxEss cloud.

My questions:
Is there a way of making changes to the charge/discharge settings without getting an RS485/Wifi/Ethernet converter?
Can I use the ethernet port to do this? Or is the ethernet port exactly the same as the wireless apart from using a different connection?

Thanks!

On the home assistant with modbus, yes you change the workmode and many other of the inverter features such as minsoc’s, maxsoc, battery charge / discharge power.

If you only have the Fox datalogger connection the Fox app (and Energy Stats) allow you to create schedules which do the same thing, but they are fairly rigid in that you set and forget whereas with home assistant you can make decisions on the fly depending on solar forecasts etc..

Some control is possible via the OpenAPI but it is very limited, will likely mean you need some programming skills to create and modify schedules on the fly.

In short the best answer is (by far) going with home assistant over modbus which does require an RS485 modbus adaptor and 2 wires to be connected to the inverters meter/ct connector which is probably the fiddliest bit to do - but once you have modbus you will have full local control of your inverter.
