Day 36 of #100DaysOfHomelab was spent fixing some issues with ESPHome devices which had fallen out of Home Assistant with the dreaded
unavailable erorr. They were all still online and could be talked to through the ESPHome editor applicaiton, but were not reporting status back. Simply removing them from the HA configuration and then restarting the device allowed them to be re-added again and all was well.
After that, I upgraded Home Assistant again as a few patch versions had come out, and ESPHome had a few more bug fixes so I patched all of the devices on the network again.
