Mitsubishi mini-splits: which WiFi smart controller can see or “know” when units are on or off? Cielo doesn’t seem to, and the on-off toggle fails. (alien.top)

As best as I can tell, Sensibo and Cielo do not know the current state of your mini-splits.

If you have a schedule to set the units on/off and someone in your house inadvertently uses the remote to toggle the on/off state, all your subsequent schedule triggers will be off — for instance an “off” action you create in the Cielo app will turn ON a mini-split that’s already off, because it’s only a basic, binary toggle.

Obviously this is annoying, so I’ve been researching for controls that are smarter. I have no experience with Kumo but I think I’d switch if I knew it had this functionality. Does anyone have any recommendations?

On Mitsubishi, some of their units have a PAC725 cable attachment and the Or/Y off that bundle will have 12v when the unit is on. We used this on dumb 14k units and on VRF. The cable attaches at the FCU. We use this to close a relay and turn on supply fans. You can use that signal for a lot.
