Plugs work great and the response is quick. No complaints. 2.4 Ghz network is what you have to connect to. I think some people aren’t saavy with their internet wifi connection which is why they’re having trouble connecting. Sometimes you have to try a second time to connect initially, but that’s not really an issue. Love the govee water sensors as well. They’ve alerted me from several occasions of leaks that saved me from having major water flooding.
