Any updates on this?
I have two Daikin mini-split head units that I'm currently controlling via handheld remote control, and I'm searching for a better option. The Puck hardware looks great, but I'm not interested in the cloud automation features for security and reliability reasons.
It sounds like after initial setup, I could just disconnect the Pucks from my network and use them to manually control the temperature. Is that right? This alone seems like it'd be a solid improvement over the handheld remotes as I could see the current temperature from across the room and make quick adjustments without having to find the remote.
It'd be better, though, if I could control the Pucks via a local API as @null suggested. Ideally, they'd accept a 7-day custom program, perhaps as a JSON object. This would allow me to create preset profiles like "Summer", "Winter", and "Vacation" and quickly switch between them by POSTing JSON from a PC.
If that's asking too much (and I suspect it probably is), the Puck could just accept commands to switch the unit on/off, change between heating & cooling, and set the temperature via the API. (Get current temperature & settings would also be nice to have.) I'd use local home automation software, probably Home Assistant, to change the Puck settings following the 7-day programs. This isn't quite as good as the above option because it will break if my network or automation controller crash, but I think it'd be good enough.
I don't know a lot about Apple's HomeKit, but I think it'd be a fine substitute for the custom API described above and it looks like this is also under consideration: https://forum.flair.co/t/homekit-support/130
