This reminds me of the kind of hack I came up with, almost 20 years back. I used to work in Bangalore, and now and then, we would have a power outage in the evening that lasts for a few hours. I was single and used to live alone. I did not want to go home from the office and find myself without power. So how do I find out there is power at home? During those days, there were no IOT devices so checking them is that's out of the question. But I did have a landline phone that was powered by electricity and had a replaceable battery as a backup. I used the phone only to connect to the internet. So I just removed the batteries and when the power goes out, my phone wouldn't 't work. So before leaving work, all I had to do was call my landline. If it rings, it means there is power.

Here in Argentina people sometimes leave inside the freezer an ice cube with a coin on top of it, so they can check if the power went off for a long while - because the coin would be lower in the cube even if it froze back.

I used the same trick recently where a long power outage had me staying at my relatives until power was restored. My answering machine doesn't work without power but the phone does so if it doesn't pick up I know the power is out.

Since the central office switch is usually powered by generators I was used to the phone always working even during outages. But I found that the landline phone only stays functional for only a day now. I believe the deployment of fiber to the node means there are battery backups at the nodes that only last that long.

Good one, Living in a place like that, I can understand how important it is. :)

How long was the commute from office to home? Depending on this you still had risks of phone working while at the office, power out when back home, no?
