Suggestion: Watchdog function in 2DS

Post by Bill D »

Every 2DS is uniquely situated to serve as a "reboot watchdog" for routers & modems.

My Linksys WRT54G router w/Tomato 1.25 firmware normally runs for many months without needing a reboot, but it seems to have just stopped running and I won't be home for a couple weeks. This dilemma is the source of my suggestion.

It seems like you could offer an in-line AC switch (reed relay, Triac, opto-isolated?) controlled from a signal from the header on the 2DS. Whenever the 2DS loses connection with your server, it would power-cycle the router/modem plugged into the in-line AC switch. You may be able to find an existing in-line AC switch product that only needs a cable to connect to your 2DS header.

Your 2DS has served me well and I may sign up for your monitoring service, but my problem today has reminded me that my current POTS monitoring service doesn't need my router running.

I'd done some searching and may have found a $99 product that will auto-reboot my modem and router if pings don't respond. It's the "Remote Power Switch" at http://www.3gstore.com

If anyone has any other suggestions for this "unattended site auto-reboot" problem, please let me know.

Enough memory in the 2DS to program a function to trigger a PGM on loss of communications? I wouldn't use it but that would be an awesome feature. Could also wire that PGM to a zone and have it function similar to "sound siren on TLM trouble while armed" feature already built in.

Joako's suggestion doesn't sound that hard to do. I'll forward this on to envisacor's firmware guys.
