One for Stratum 0 NTP server (using GSP module with PPS)
One for Home Assistant
One for monitoring the solar power at my cabin, using a 4G USB device to send data home.
The Home Assistant runs on a 4B, the others are using 3B's and a clone (NanoPi Zero).
Got some Pi 4's that I use for various Linux experimentation and such. Sometimes I find it easier to get a Pi 4 up and running than a VM, and other times I need the GPIOs.
