!!Work in progress!!

This is an alternative to https://github.com/CoMPaTech/esphome_c1101 which should handle most things within ESPhome instead of offloading controls to HA

This has no support for the timers and just one additional switch for the join command

ESPHome ITHO control

Trying to get ESPHome to mimic what is comprised in

How-to

Not tested from HA yet, just from CLI. Assumption: you have a machine ready with the ESP8266 and C1101 connected to it.

That machine is also ready to go as instructed per https://esphome.io/guides/getting_started_command_line.html (pip install)

• Copy itho.yaml and c1101h to a directory of choice
• Run esphome itho.yaml run and watch the magic happen
• Go into HA, choose integrations and add your ITHO
• If everything goes well, you'll see the fan within HA
• Enjoy!

Wiring schema used:
