My lastman project worked, got a bunch of SMS messages when the UPS for my stack of switches died.
I looked at when I purchased this UPS, July 2021, so yeah 4 years, need to be replaced.
I got quality batteries, this is a very important stack.
Another thing I got done was listing devices and entities via python. Yesterday I got it working with curl/bash. Here is my code for python
