Hello everyone,
First post here, I hope it’s the right place/category.
I’d like to jump into heat pump monitoring but don’t really where to start. I’ve tried to understand which solutions Open Energy Monitor has to offer but I’m not familiar with MBUS, RS485 and all…
I live in Belgium, I currently monitor my electricity consumption and production through different brands (myenergi for EVSE, SolarEdge for PV inverter, smart meter, Shelly and Meross for home appliances…) and Home Assistant to gather them all.
I’ve just got an air source heat pump for my pool (BluePlus Full inverter 11kW) and would like to get more info from its COP.
I already have an Shelly 4PM connected to it which gives me its electrical consumption… It’s a start but I’d like to know how efficient it is on the long term and how to make the best use of it.
I know the inverter has an RS485 connection available but it seems to be for control and not monitor the appliance:
(sorry, it’s in French, I can translate it if it’s relevant)
I can control the temperature and modes through Smartlife app (and so HA), though.
On the poolhouse, there’s WiFi and Ethernet RJ45 plugs available.
So my questions are:
What should I buy ?
What price range should I expect? I’ve seen some device like the Diehl Sharky 775 but I’m not sure if I’m ready to spend 900€ “just” for COP monitoring.
Thanks in advance for taking the time read and answer, any help is appreciated.

P.S.: I’m planning on buying an air-air heat pump for the house later this year or yearly next year… But that’s maybe a story for another time
