what is the use case for this?

Probably around 80w, maybe 90. But lets say 80. 802430=57kilowats a month… Rpi with hdd wont draw more then 15w, maybe 10-12w. So thats about 8-10kilwats a month. So basicaly about 6 times more electricity.

Well its homelab, setup homeasistant or openhab and add some air sensors and temp sensors near “problematic” devices and parts and make it send mesages to phone if anything goes out of normal values. Even shut everything down automaticaly. The beauty of home automation 😀
