I have an HS210 3-way switch that is behaving oddly.  It was setup in the Kasa app but controlled using an Alexa device.  Occasionally (maybe 1 out of 10 times) when I give a command to turn it on, it will turn on and immediately turn off.  Alexa plays a different sound for turning on than it does for turning off, and when it does this, the sound is the "turn off" sound.  I have 5 HS210 switches installed in my house, and this one is the only one that ever does it.  I've confirmed the switch has the latest firmware.  Any thoughts as to what's going on with this?
