Successfully remotely upgraded the esp8266 lighting controllers in the camper from #Tasmota to #ESPHome. Managed to brick the two #WLED controllers so they'll need a physical connection to sort out. The single esp32 based relay board also needs a physical connection - Tasmota on that won't let me 'upgrade' to esphome firmware.
After they're all done, I've got to work out what I did with the #zigbee controller that means it's not on the network. Then I've got to program the switches...
