Characteristics
| Characteristic | Optional/Required | AcceptedValues | Description |
|---|---|---|---|
| On | Required | true, false |
Active status. Default: false |
| OutletInUse | Required | true, false |
In use status. Default: false |
Using an outlet as an Internet Down detector and reset your modem automatically when internet access is lost.
For this use case, I have an outlet module ( in my case a WION Outlet ) that has my router plugged in to it and flashed with TASMOTA.
In TASMOTA I have this config
PowerOnState 1
SetOption55 1
WifiConfig 4
rule1 on wifi#disconnected do backlog power 0;delay 150;power 1; delay 1800 endon
rule2 on system#boot do ruletimer1 600 endon on Rules#Timer=1 do backlog power 1; ruletimer1 600 endon
rule3 on Mqtt#Disconnected do MqttHost 0 endon
rule1 1
rule2 1
rule3 1
rule1 : upon disconnect, switch router off, wait 15 seconds (think it's enough for 'cold boot'), power router on, and wait 180 seconds for router to boot (if no waiting - sonoff will reboot router in loop, because router cannot start WIFI immediately upon powering on).
rule 2: just power router ON every 10 minutes. That's in case someone (or you) incidentally switch off router remotely - you cannot issue the command for powering it on back. So even if you powered off your router, it will be back ON for less than 10 minutes.. YOU CAN OBEY THIS RULE - router will be powered ON back due to rule1 in case you power it off.
rule 3: If Mqtt is disconnected, reset and use mDNS to discover MQTT host again.
SetOption55 1 - Enable mDNS
Wificonfig 5 - that issued command to don't try to access other AP, but just wait and connect to AP in interest... Otherwise Sonoff can connect to other AP and thinkink WIFI is OK even if router is not working...
And my node-red / HomeKit-bridged flow to monitor the internet connect and restart as needed. Besides the HomeKit-bridged node, it also uses the ping node.

Once you import this flow you need to change these nodes for you environment.
1 - MQTT -> Internet Down - Update server and topic for your MQTT server and topic of your outlet.
2 - HOMEKIT -> Internet Down - Update bridge for you HomeKit bridge and topic for your outlet.
3 - EMAIL -> Internet Down - Update the email address to your email address.
4 - FUNCTION -> If down - Edit function to use your outlets topic.
5 - INJECT -> Status - Update topic to your outlet
