I am experiencing this too. I have four Blue Series installed on Hubitat. Three of the four ended up “bound” together and the behavior is inconsistent in that occasionally all three of those operate in unison and at other times the three will respond correctly to specific commands. So far I cannot replicate the issue when using local (button press) control but my sample size is short as of yet. I am installing v2.05 right now. That’s the most recent firmware available to Hubitat as of 7 Nov.
Anyone else find another way to overcome this issue? I’m dead in my tracks installing for fear of the inadvertently turning on the kitchen lights in the middle of the night and waking up the rest of the house 
…wouldn’t be the first time…
