I have a smartthings environment already. It has a V2 hub. I recently bought some new First Alert smoke detectors (SMCO410) and could not get them to add. I read that they don’t play well with V2 hubs but work OK with V3 hubs. I have a V3 hub that was used at a different location. I’ve been trying to get it to add to my system. I’ve done the hard reset (hold reset the power on, wait for solid yellow and release reset). The hub shows up in the web console without a firmware version. My app sits at downloading updates. I pulled the power during the download phase and plugged it back in and the screen changed to a status bar. That got to 99% and eventually (several minutes) failed.
Is there a better process to get a new hub added to my smartthings environment?
