The first C-7 hub -- software updates using the phone worked okay a couple of times. After that the phone app showed "in progress" for several hours. Generally, I was able to use Hubitat web UI the next day on the computer browser. However, even that failed. From start to death, the C-7 lasted a few months. Hubitat support sold me a replacement for $60 + shipping.
Setup the replacement, registered the hub and upgraded to the latest firmware using the web browser. I was able to attach the phone app. Couple of days later I could not get the UI on the web browser or the phone app. Ping shows 30 to 60% loss. Hubitat support sent an automated ticket number but has not responded.
I like the concept and would like to use the Hubitat. Why Hubitat? Can you (the community) help?
