@Wayne-TP no one other than me has access. I've reconnected the hub to wifi and connected back all the valves. Was working great then this morning I notice the hub is blinking orange and blue again!

@Wayne-TP Light on hub is blinking blue and orange. I considered getting a new hub, but can't find anywhere that just sells the kh100 hub.

I have 5 radiator valves connected to my hub. All working fine till I noticed last week the hub was offline. The only way to reconnect was to reset hub and reconnect the valves. The hub went offline...
