A tad cozy for the garage (plus it'll never get there if its low teens outside, so will just run 24/7); in winter only really concerned about pipes freezing - this isn't my living room. I'm also good with turning the heat on manually if I'm going out there...

Interfaced to the mini-split via a CoolPlug/CoolLinkHub unit from CoolAutomation. Had to add the Daikin add-in board (cheap enough on Flea Bay).

Result: I could control the mini-split directly from a web/phone app (CoolRemote). Which had the same stupidly high minimum settings (corresponding to the built-ins for the mini-split, I suspect).

The last piece was to integrate to a Nest (provides all kinds of smarts and/or scheduling I don't actually use/need). And then run that in ECO mode.

So now the mini-split sits idle when not needed - and "wakes up" when temps drop below 40F or rise above 85F inside the garage. Or exceed specified "emergency" temperatures, regardless of schedule/user settings on the Nest (eg override "OFF" setting if temps drop below 35F).

The integration stuff was not cheap. However, the end result is not running heat 24/7 when it's above freezing outside, "warm enough" inside - or neglecting to turn it on when there's a cold snap. So pretty much feels like a win. Also nice to check remote Nest sensors from your phone when it gets into the low teens outside...
