Pinging across Wan help (alien.top)

Hi all,

I had a new idea for a homelab project, but I'm having trouble coming up with the best course of action/ technologies to use to make it happen.

I want to be able to tell when the power goes out at a building that my dad owns. When he had a telephone service there he could call the phone to see if the power was out, but the phone line is long gone. We just had internet installed in the building and I had the idea of using that to probe if the power was on remotely.

My idea is to simply put a raspberry pi on the building network and have it update a duckdns reservation with the router's wan ip, then I can run a script on my home network that pings the remote router every few minutes and updates a webpage that I'll host with the status, etc., etc.

Does this idea sound like it would work, or is there a better way to do this? I'm trying to keep it as simple as possible.

Thanks for any help, love this community!

If you have a pi there, why not just just zero tier to that pi and monitor it's zero tier IP? You can do a very basic keep alive check with any monitoring system that can ping and then alert trough whatever script that monitoring system can call.

Or just have an old android phone running macrodoid and keeping that connected to usb power all the time.

If phone is no longer connected to power, send a text, call a number, write an email etc. You will need a sim card though. But one with very limited data can be had for very little money.
