I’m using a Raspberry Pi to communicate with the power equipment in my homelab rack; the UPS, ATS and PDU. For the UPS, I’m using NUT (Network UPS Tools), and for the ATS and PDU; my own PowerWalker Python library.
In this post I’ll be going through how I’ve set up the NUT server to communicate with my PowerWalker VI 1500 RT HID UPS, and NUT clients running on all other physical machines in the rack.
