But i think one of core causes is slowness of bridge http API. Testing from Chrome dev console info endpoint lasts sometimes 5s sometimes 8s (measured inside LAN)…
I had the same issue. Unplugged the bridge and replugged worked for me. Since I had two bridges I really could see the slow bridge. Both bridges are running with 2.60
Bridge API is slow - see graph from Nagios below (units = seconds)
Bridge API is unreliable - returns random 503’s - see graph from Home assistent connected to bridge API. Grey bars on graph are “unavailable” states during last 24h.
So bridge API is really broken! I think someone from Nuki should fix this ASAP. I am not only one with this bad behavior of bridge (info taken from HA forum).
