Hi, we have approximately 20 Kasa Smart Switches in our house.  We love them but I've noticed some weird things recently. 

About three weeks ago, I noticed that all the lights would randomly turn on for about five seconds and then turn off.  Last week they did it again during the middle of the day.  This morning around 4 AM every light in our house turned on and turned off while everybody was sleeping.  The weird thing is that it's only limited to the light switches and it only turns on/off devices that are off at the time.  This morning our ceiling fan was on when everything turned on and it stayed on when the other switches turned off after a couple of seconds. 

The switches are scattered around our house and not at the same locations.  We do have everything integrated into the Google Home app.  We did switch internet providers around three months ago and switched from cable to fiber.  Our electricity isn't going out as nothing else in the house changes, just the smart switches. 

Here are the switches that we have:

Several HS200 H/W Version 3.0 Firmware 1.1.4

Three or four HS220 H/w Version 1.0 Firmware 1.5.11

Several HS210 H/W Version 2.0 Firmware 1.1.4

Any ideas what might be going on?
