It’s great to have a WiFi thermostat—you can change the temp in the middle of the night from your iPhone which is always by the bed! Or on you way home from a out of trip. Turn it back on so the temp is just right when you walk in the door.
We could get my wife's Apple X10 to work, but the T6 will not work with Samsung 8 or with Samsung A71. We had an engineer come around to try and they could not do it either...
At my previous home I had an EcoBee thermostat, but upon moving to my new home was provided (3) Honeywell units in a zoned configuration. I found the Honeywell as robust as the Ecobee and much easier to configure and use overall!!!
