KH10 options for connecting Home Assistant via RS485
Posted: Sun Aug 23, 2026 11:32 am
Hi
I have a recently install KH10 with 15 Aiko panels, an EP12 battery and a WLAN_WW datalogger in the USB port (G in the manual). I also have a CT clamp plugged into the RS485 port (N in the manual). It doesn't appear that the datalogger (firmware 2.05) offers RS485 over the network, the only live port appears to be 443, for the web UI. This version of the KH doesn't have built in wifi and it doesn't appear there are any spare ports underneath to plug in a third party modbus/serial to ethernet dongle.
What are my options for getting a local RS485 stream, as well as keeping access to the Fox cloud, as well as keeping the input data from the CT clamp? Do I need to replace the datalogger with another (Fox) model? Or can I insert something between either the CT clamp or the datalogger in order to tap into the RS485 data?
My goal is to access the high resolution data (5 second interval) to more accurately manage car charging current. I've been able to get some of this through Home Assistant using the websocket approach, but it seems a little fragile and could be pulled at any time if Fox modify their app.
Thanks!
