I'm looking for a UPS device I can plug into my home router that has just enough power/smarts to send an email or SMS message before it dies and another one when power is restored. There are a few home alarm systems that will use cell service to send text but they seem to be add-on components to alarm systems and generally don't support Canadian cell providers (even presuming there wasn't a monthly fee).

Seems like something that could be built cheap.

Thanks

I had a similar wish, found records of a no longer made device, nothing currently commercially available.

You could do it with a smart UPS tied to a computer but that’s a big investment.

What about a small LED lamp before the UPS and a cheap webcam after the UPS? Light goes off, webcam sends message. If you have an old smart phone laying around there are apps that will do it also.

How does the webcam send a message w/o power for your router, monthly cell phone plan?

It seems like something that could be simply solved with an android or Pi box. Short term UPS for the modem/router and an android device (ie old phone w/o sim) on your home wifi plugged directly into the wall, when android detects it's been unplugged, send an email, send another one when it's back on power.

how about a traditional UPS and smart outlet or plug? plug the router into the UPS and the UPS into a smart outlet or plug. when you lose commercial power the router stays up via the UPS and the smart plug/outlet sends a text or email.

An example of something that will last long enough to send your message. One side for UPS and router the other side for a smart alert which is not UPS protected.

You could use an Arduino - and have it use either an external cell phone (an old one) or a GSM module that comes with it - so that when the AC power is lost, the UPS would hold while the arduino continues to run and sends out a text message (SMS) that the power is down.

There are UPS's that have USB connectors that close or send a message that power is lost - but you'd need to find one that has software already for the Arduino.

I just checked Craigslist.com, Dallas (were I live) and found 5 of them for sale. Priced $50 - $150. Check out your local craigslist.

I have had one in-line since the 90s. If/When the power goes out, mine will power the laptop for 2-3 hours and a string of LED lights (probably) for months.

APC has several Smart UPS with optional network management cards that will do what you want without an attached computer but it will cost you big $. The network management card connects directly to your router and has its own built in email client with a web interface for configuration.

Right but how does the laptop then remotely alert you that it's on battery power?
