Can I get a Sonoff to give me a contact if loss of wifi. ? I can reboot my modem. Then; if you can give me a loss of power contact; failsafe i guess as it sonoff module sees power it latches in a relay. Loose power; contact closes. OK; Then I know power is going or wifi; router needs a reboot ! Then if there was an app to include this features; switch; It can notify me !
