I have 7 to 8 HS200 units all over my house.   Two units keep disconnecting from the application.   In specific I have tried now to reset them multiple times.    After few attempts at reset I can get them to connect and also work, however next day they are both again disconnected.    Wifi signal was the first culprid.   I checked and signal near these units is strong.   I also put them on a net new wifi network with no other devices hence channel traffic as an issue was eliminated.   Still no change.

I updated the firmware as well to latest firmware from inside the application.   I am at wits end.   It seems these two units are the only ones w an issue.   I have two other smart switch units in the same gange and they work just fine.    

Is this a known issue?   Is there any suggestions or fixes?   

Quick edit:   I had these installed last year and they worked for some 10 to 11 months perfectly.   It seems at the time that they start to misbehave was somewhere around 3 weeks ago when I both updated the firmware on them, and then after changed my wifi password also
