Investigate wifi robustness

[jonahshader]

We have not tested what happens when the wifi cuts out yet. The esp32 might auto-reconnect or we might need to reconnect manually. wifi.keep_connected() should be called periodically, but only when the wifi is properly configured since it is blocking and would make the system unresponsive as it tries to connect.

Maybe add a function _is_valid to indicate that the wifi config is believed to be valid. "valid" here means that the wifi has been connected to before. only run keep_connected when _is_valid is True.

If the wifi is confined to 2.4GHz after connection, the cutout seems to confuse the panel. It stops controlling zones but becomes happy again if rebooted while the 5GHz is still off. BTW. Sonoff has major issues with customer education around their devices inability to set up on 5GHz and we may have inherited their continual need to warn users to switch to 2.4GHz during setups.

Thanks for letting us know Rick! It looks like we will need to do some testing on how a wifi connection is established when a 2.4 GHz network and 5GHz network with the same name (SSID). @klay2000 reminded me that for some IOT devices you need to disable the 5GHz network momentarily to establish a connection on the 2.4 GHz network.
