Hey Glyn, Looking to replicate what you did with the Samsung Gen6 for the Gen7 units. Struggling to get any sensible data out of it. Cannot get flow rate or outside temp etc. Any ideas or help appreciated. Cheers

Do you have the modbus module installed? Samsung Modbus interface MIM-B19N Modbus interface to allow connection of Samsung heat pumps to modbus control systems and Homely thermostats, <i>code: MIM-B19N</i> If so, you should be able to use emonHub with an RS…

We have the modbus interface installed in the outdoor integrated unit. It is connected onto our network using a Waveshare RS485 to ETH (B) POE device. We use these for all monitoring and metering. Inverters, batteries, remote CT etc. All we can get out of it is LWT RWT and by accident FR. These are…

There’s a list of all the modbus registers in this repo: GitHub - glynhudson/samsung-modbus-mim-b19n: Example script to read data from a Samsung Heat Pump or HVAC unit using MIM-B19N Modbus module · GitHub If you want additional information, then you may need to talk directly to the heat pump bypas…

Thanks for adding the references, @glyn.hudson and @toadhall .

Hahaha, I forgot about that :rofl:

Thanks all for the replies. I have a Gen7 Integrated unit with the cabling from outside to in and into a Waveshare RS485 to ETH (B) POE device. The installer put a Modbus card in it and wired it. Not a 5 minute job to take the case apart and rewire it. I can talk the modbus card but it seems limited…

Have a look at Samsung HTQuiet 8KW Idle power consumption 60W? - #16 by toadhall . (I don’t speak Modbus but the GitHub link @toadhall provides appears to point you some relevant registers.)
