OK so bare with me. The 'Wireless' version of these that you get from JB Hifi includes an unsightly cable that runs from a wall wart to the 'wireless' unit.
The 'wired' version is integrated into the wall, like a light switch. Which then became 'wireless' from an aesthetic point of view.
This version includes the Tado smart internet bridge.
The interface of the Tado is, in my opinion, the best on the market. HomeKit integration is seamless.
Until Meross make an AC split system model, this is the go to.
Hope it's useful!
Note: UK power supply.
I use a $25 Aliexpress smart IR blaster with my Fujitsu split system. It plugs into any old USB port and has its own temperature sensor.
It gets the job done, obviously wouldn't work with a ducted system but it's a cheaper option for splits.
