Controlling ITHO Mechanical Ventilation

: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 :)

Requirements

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

How-to using Home Assistant

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!

Current status:

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