:alert: This repository was updated after too many years of being stale :alert:

I've removed everything that wasn't working any more and provided a more clear way how to add this.

For previous notes, please dive into the older commits :)

• An ESP8266 (or compatible)
• A C1101 board (including coil)
• Some tinkering see Mechanics
• Manually placing some files inside of Home Assistants /config/esphome directory

Ensure you have the hardware ready (Mechanics) and the esphome add-on installed

• Copy the directory structure of config into HA's /config (or manually ensure you have the dir ITHO and it contents present in /config/esphome and start configuring from the UI
• See the sample contents in /config/esphome/itho.yaml for some idea of what is neccesary (obviously needs keys and secrets changed)
• Build and install on the ESP of you choice from Home Assistant
• Go into HA, choose integrations and add your ITHO (it should auto-discover it).
• If everything goes well, you'll see switch.fansend... and quiet a few others popping up.
• Enjoy!

• Sending High/Medium/Low and the Timers work
• Reading state and indicative time (not counting down (yet) - should HA or ESPhome do that?)

Trying to get ESPHome to mimic what is comprised in
