I am regularly getting an email:
We haven’t heard from your Smart Weather station named “Davids House” in a while. The two most common reasons for this are (1) your WiFI is down or (2) your home network is offline. You can also try unplugging the WeatherFlow hub for 10 seconds - then plug it back in. For additional help, see troubleshooting tips.
And then anywhere from 1 to 45 minutes later, I’m getting another email saying I’m back online.
My Wi-Fi is never down, and my home network has redundancy with no loss of Internet connectivity.
