About 80% of the time, my Echo Dot responds with "Sorry, TP-Link Isn't Responding" when I ask it to turn on/off the Wi-Fi plug. The plug otherwise works fine with the Kasa app on my phone, but very sporadically with the Echo Dot. I also have an Ecobee, and I have never encountered an issue with its interface with the Echo Dot.
Does anyone know what the issue is with TP-Link?
