# 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](#mechanics)
- Manually placing some files inside of Home Assistants `/config/esphome` directory
## How-to using Home Assistant
Ensure you have the hardware ready ([Mechanics](#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?)
