Watchdog OUTPUT Pin

Hello,

I have a RUT241 and I would like to use the OUTPUT pin to restart a WLAN device if no feedback is possible by pinging via WLAN or UDP. The check of this external watchdog should happen in a certain interval. Is it possible to implement this via a script or settings in the router? I would be very grateful.

Greetings

Hello,

Our devices are unable to restart other devices connected via WLAN, especially if no feedback via ping is received. Could you please provide more detail about your desired solution? Currently, it’s difficult to understand what you want to achieve.

Kind regards,

I have an ESP32 which is connected to the RUT241 via WLAN. I would like to connect the OUTPUT pin of the RUT241 to the EN pin of the ESP32 so that the RUT241 can restart the ESP32. In my case via external access (e.g. SMS). However, I would like an automated solution so that if the WLAN connection between the RUT241 and ESP32 is lost (or does not respond in any way), the RUT241 sets its output to restart the ESP32.

It should be an external watchdog solution in case the ESP32 freezes and the internal watchdog does not initiate a restart.

Hello,

This explanation clarified things. Yes, it’s possible, and the cleanest way to do it would be through a script that adjusts the output value if a ping to a specific host fails to reach its destination.

Since you mentioned using SMS to trigger this event, there’s a slightly messy but quick workaround. You can set up a Ping/Wget reboot to send an SMS to the router itself if pings don’t reach the destination. This can be configured via the web interface and should be pretty straightforward.

This is an example of the configuration should look:
