That’s incredible. I have an airtouch which I love but my parents have a Mitsubishi system that I’m fairly sure would be compatible, and a large floor space to manage. Apologies for the question, but for multi zone, you mention that the controller can pick up temperature. My understanding was that temperature is only captured at the intake, not in zones? (I’m familiar with airtouch where I have ?BTLE temperature sens…

Thanks! I just took a look at AirTouch. It seems they have a nice ecosystem. Their Mitsubishi Electric offerings [1] use the CN105 port (like the OP's device). I use the word zones on the Serin Multi Zone product page but it's interchangeable with indoor units. One indoor unit equals one zone. You can override the room (intake) temperature per indoor unit/zone using a controller plugged into the CN105 port (like the…

I appreciate you taking the time to reply - that helps a lot. So essentially I get this and plug it into the CN105 port, and then everything will be in home assistant and I can get room/zone temperature control via BLE as well.

Spot on. If you're using Home Assistant, you can push any temperature sensor available. Zigbee, Zwave, BLE, 433mhz rtl sdr, etc. At one point, I was using the proprietary temperature sensors that were paired with my ecobee thermostat (for my ancient natural gas fired hydronic boiler). For the BLE sensors, your HA server must have bluetooth capabilities. I use a bluetooth dongle attached to a short USB extension cord.
