I’m not sure why this is the first thread that comes up when searching “Baseboard Thermostat” in the search function. Website limitations I guess…
I have replaced two baseboards that had the similar setup. So far I’ve been most happy with the Stelpro Ki line. In terms of ease of use, that thermostat is the most straightforward device I’ve seen yet. I used webCoRE to create a complex schedule, but it would be easy enough to create a basic schedule with the apps and device types discussed in the thread I linked.
I also have a Nest for my main living space, but that required some creative engineering to get it to work, and the brain in it likes to fight my automations a little too much…
