Having a bit of spare time this days I wanted to order a Heat pump monitor Mbus based Rasp Pi hat from Open energy shop for my Ground source open loop heat pump monitoring project.
I do have a MID approved heat meter installed some time ago but just realised it is not the MBUS protocol.
Instead there is a label rs485 Modbus on the 4 wires cable.
I also have a electric meter with the same Modbus protocol.
I have tried to get more info around here but I couldn’t find to much info on Modbus heatmeters.
Has someone successfully read this kind of heat meters?
Or, is there any Modbus interface that can be used on the Raspberry pi hat, so it can read the heatmeter and the electric meter the same way it reads data from MBUS hardware?
