I have 4 HS200 switches in my garage with a router located inside the garage about 5 feet way. Two of them are V2 and two are V3, neither of the V2 switches are very reliable and it seems like one of them has recently started to only work for a few minutes after being reset. It is grayed out in the kasa app and Alexa tells me it is unavailable.
I also have an HS300 (6 plug outlet strip) that has to be reset every now and then, but much less frequently than the switches.
Is there anything I can do to make the V2 switches more reliable?
