hi @oatspie , I’m interested in your idea of future Pi-based controller for the Midea HP. I’m planning to integrate the PI-based OEM Heat Pump Monitor with a Midea ASHP next month and while this would only be used for monitoring not control, I’m wondering to what extent to could be extended to handle some additional control tasks if necessary.
I believe the Midea is controlled over modbus so not native to the OEM monitor currently (i believe) but could be enhanced I imagine as its using MBus.
Not to go off-topic but slightly concerned by the issues you’re getting with the Nest (my set-up will also have Nest-controlled zones, illustrated). Are you using the Learning controls or as a simple time programmer and remote control? I might PM you on this if I may…
