Bell Fibre Internet is awesome however the HomeHub 3000 router they provide is rubbish. Recently we were away from home when there was an internet outage requiring a router reboot fix.
Our home is smart so losing Internet while we’re away caused a few problems;
- The front door camera was not accessible to we couldn’t check if packages had arrived
- The thermostat was not accessible so we couldn’t warm the house before our arrival
- The Plex (self hosted Netflix) server went down we I had to read a book
- We couldn’t run the vacuum cleaner prior to our arrival or drive it around the house to check for post storm damage
After a bit of research I decided on the Watchdog for Wi-Fi router approach with a few tweaks. I built a version of Tasmota with
USE_PING allows me to write Tasmota Rules based on the response of network pings.
SUPPORT_IF_STATEMENT were added in case more complex Rules were required later. For instance, adding the ability to ping multiple servers to check for network connection. I flashed a Sonoff switch with my build of Tasmota version 9.1.0 using Tasmotizer. Then connected the switch to my router’s wifi network and in line power supply.
In the console;
Set the PowerOnState to 1 so that the router would turn on after a power outage
Then added a rule which sends 8 pings to 18.104.22.168 every 120 minutes and if there are 0 successful responses, it powers off the router for 15 seconds, then powers it back on. I choose a 2 hour cadence because a 2 hour outage is fine for my use case and I didn’t want to risk a reboot loop if 22.214.171.124 stopped responding to my pings.
Rule1 ON Time#Minute|120 DO Ping8 126.96.36.199 ENDON ON Ping#188.8.131.52#Success==0 DO Backlog Power1 0; Delay 150; Power1 1; ENDON
Finally I enabled Rule 1.
I’ll try this approach out for a while and if reboots become too frequent I will use the
SUPPORT_IF_STATEMENT to check multiple sites before initiating a reboot.
