Modbus Proxy help needed

Hi all,

does anybody have mmodbus proxy runniig and give me heis/hers/theirs sample configuration?

I have a SMA Inverter, a Solis Inverter, a Felicity Battery, an Eastron counter, a Zehnder Comfoconnect a Nibe Heatpump and a Besen clone wallbox (Telestar, as soon as it arrives replaced by a Warp 4). All speak Modbus. I also tried the EVCC modbus plugin without success..

I just do not manage to have my inverter(s) and the heatpump talk to each other to use the surplus PV production for hot water heating.

Anybody had a similar problem and solved it already?

Would one of these help?

Thankls, but I guess not really.

This is an external device. I need all modbus devices to talk to each other via a Modbus proxy (modbus and Modbus proxy are available as iontegrations for HA. I just need a sample configuration of somebody running a modbus proxy on HA to logically understand the structure of the yaml and then adapt it to my situation. I searched the few forum threads about that but I still do not get how to configure it.

My thought was it might give you third party access to the bus so you can tell what's happening and later maybe automate some stuff as well.
