I have an Ecobee 3 lite thermostat at two different locations…one at a primary location where my HA green is and one at my secondary location that is on a different network. Is it possible to have these both added to my HA?
I have the first Ecobee added via HomeKit integration at my primary location where the HA physically is. Am I able to bring my HA to my secondary location to add the other Ecobee via HomeKit, and then bring my HA back to my primary location and still have both connected?
I won’t need to control the second Ecobee in real-time as I’m planning to setup some automations for it. Ideally, my idea above works but if not, would it work via Home Assistant Cloud? Or any other ideas?
That won’t work. Homekit is a local only connection. If you add the one at your alternate location and bring the HA unit back, it won’t be able to talk to the alternate location unit.
Unless you have a complete second HA setup at your secondary location, Home Assistant Cloud isn’t going to help with this either. That is meant to let you connect to a Home Assistant setup at some location when you aren’t there. It won’t bridge random devices between your locations.
There is an ecobee cloud integration, but according to the information there, Ecobee isn’t letting people create the needed API keys anymore, so that’s not an option either.
Someone might come tell you it’s possible and that “all you have to do” is a site-to-site VPN between the two locations with the right settings. Unless you are a seasoned network engineer, that way leads to madness.
I hate to say it, but I don’t think there’s a solution for what you are trying to do, although I’d be happy to be proven wrong.
