I have created a new router to get better WiFi. In the process I lost access to my habitat hub. I have done the following things that I’m sure are wrong and not sure where to go.
removed the hub. I couldn’t access it so I removed it.
Not sure what you mean with "remove" or how you're trying to access it in the first place, but in any case, the first thing I'd try is a network reset on the hub:
This should only be necessary if you set a static IP (and if you new router uses different ranges that could explain your problem), but it can't hurt regardless.
Also, if you haven't tried using http://findmyhub.hubitat.com to search for your hub on your network yet, I'd try that after (or even before) the above.
Thank you to everyone who replied. Somehow when I got home from work, the hub was able to be added back onto my log in easily and everything was still set. I don’t know if that was the recommended way, but unplugging it and putting the Ethernet into the new router then powering it on enabled it to all sync back together.
