4 smart plugs all blinking blue
I have four of the same plugs that I've been using for over 6 months with no issues. I have them turn on in the morning and off at night with Alexa commands. Yesterday they all started blinking blue in the middle of the night. The Kasa app is having problems seeing the four plugs, they keep fading in and out as "local only" or disconnected. I've updated the firmware, tried reinstalling and factory resetting one, and they are all still blinking. I haven't changed anything, and my wifi is very fast with no problems on any other devices. What's going on?
