Currently have 18 Kasa smart switches in use in my house (HS200/210/220).   Recently installed an HS200 for my bathroom fan, replacing a standard 110V toggle switch.  I also have two HS220 dimmers in this same electrical box for bathroom lights.

The HS200 switch will occasionally reset itself and show the blinking green/orange wifi light (total of 4 times over 1 month so far).  The most recent occured after I manually turned the switch on.  A few minutes later it was in setup mode again (blinking green/orange).  I believe the three prior disconnects/resets all occured while the switch was off..  Each time I have had to remove the missing switch in the Kasa app, and then I add this switch back in with no issues.  This most recent disconnect/reset occured after two weeks of proper use.

Connection strength is shown as -38 dBm for the HS200 with the issue.  The other two HS220's in the same box show -59 dBM and -63 dBM.  Note router is literally 10 feet away.

Thoughts?   Out of 18 switches, this is the only one that has given me any issues.  I've been using the switches for 6 months.
