Help choose fail safe relay wifi/zigbee/zwave

hi All,

I have a humidifier which I am currently controlling with a WIFI 120V switch from sonoff. knocking on wood nothing bad happened, but I can foresee that if the wifi goes south, of home assistant, the switch may be left in an ON position, where this means my house humidity may go ‘through the roof’

Are there any switches / relays which have some sort of hartbeat to prevent a runaway scenario?
Or any suggestion how to tackle such critical application with HA?

Thanks in advance.
