!!Work in progress!!

NOTE - this repo uses custom-HomeAssistant scripting

If you like native ESPhome scripting and 'just having a fan' in HA, use the alternative repo

As per request by @jodur there is also is https://github.com/CoMPaTech/esphome_c1101_alt which is a quick (but working!) demo of (ab)using the ESPhome fan & output

ESPHome ITHO control

Trying to get ESPHome to mimic what is comprised in

• https://github.com/adri/IthoEcoFanRFT / https://github.com/supersjimmie/IthoEcoFanRFT

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 sensor.fanspeed, sensor.fantimer and a couple of switch.fansend*** popping up.
• Now include the contents of HA_configuration.yaml in your Home-Assitant configuration and reload HA
• 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?)

Current issues:

• How to have 'multiple' switches like we have multiple sensors -> for now comprised using template fan in HA

Fixed issue

• Adding join command switch as requested by @danieldotnl and as well by @tomduijf
• Adding 'fan' control in HA
