Thanks to everyone who responded. Although I found the problem (A/H circuit breaker was turned off), it was still useful to know that a clogged drain line could cause a similar problem. I had flushed the drain line a few months ago, but was not aware that it could also be a reason for shutdown.

Update: Problem solved. In our home (Cottage Villa in Gilson Loop, Village of St. Catherine), the Ecobee thermostat is wired into the same circuit breaker that controls heating. On my circuit breaker panel, that circuit breaker is labelled "A/H", which I assume means "Air handler - heating". A couple days ago, the Empty Nest service did a house check and one of the things they did was to turn off that circuit breaker - assuming (I guess) that a house in Florida during the summer does Not Ever need to have heat turned on. I had my neighbor flip that breaker back on, and the thermostat powered up and is working fine now! Thanks Neighbor!!!


I'm away from Florida right now, and my Ecobee thermostat is telling me that it's 'offline'. My Ecobee cameras are working fine, so I know it's not a problem with my wireless router or internet. I was just wondering if anyone has identified which circuit breaker is used to provide power to the thermostat. A few months ago, I went through the entire house and figured out which circuit breakers controlled every appliance, outlet, lights, etc. But one thing I forgot to check was the thermostat! I'm assuming that the thermostat is wired into a circuit that provides power to several other 'items' (since it doesn't draw much power). Maybe someone has checked this out already and can give me a hint? I realize that just giving me a breaker number would be meaningless, but it might help if you could tell me how they labelled the breaker on the panel (i.e. "Kitchen outlets", etc.), that might get me closer to a solution. Worst case, I can just have someone flip off each breaker until the thermostat loses power, but that is a little much to ask a neighbor to do for me!
