Is there possibility to get data from modbus device connected not directly to openhab device but for example to different rpi? I have energy meter that cant be connected directly to the oh server. I would like to use second rpi to send data by ethernet

One approach would be - “Make your own Modbus gateway” You would need a rpi script that talks serial Modbus to your meter, as a Master. And talks Modbus-TCP over ethernet, as a Slave, which can be polled by openHAB. Ready made gateways are relatively cheap if you do not have the skills. Alterna…

I can confirm that the “over engineered solution” works very well for me in a similar setup. On a Pi3 the overhead is not an issue. A Pi0 won’t work in my experience.

Same topic [image] Modbus rtu master reading via modbus tcp from modbus rtu slaves I am looking for a solution for remote reading of a Modbus-RTU-Master from a MODBUS RTU Smart meter like Carlo Gavazzi EM340 on long distances not having a direct 2-wire connec…

Thanks for ideas! I will try with remote binding.
