My Smartttings hub went off line last Wednesday - the reason for the crashing is still not known but their is a conflict with my Hue hub and the fact that I have 50 hue bulbs - turn off the hue and smartthings works, turn hue hub on and about 12 mins later it freezes and goes off line - Support are aware of the conflict and are working on a solution wanted to see if I was the only one -
