I just set this up for my home, and thought I’d share my config for anyone else who comes across it.
I have the ITHO CVE ECO RFT SE, which supports 3 modes - low, medium, and high. It also has the timer function.
I followed the guide in Dutch to install using ESPEASY on my ESP32, and connect it to homeassistant via mqtt.
Unfortunately I struggled a lot with the code that in the google doc, I think there might be some errors there. It also seems somewhat outdated.
In the end I settled on the following:

This is how it looks in HA:
There’s a few changes there, but the most significant ones are:
- my fan can’t be turned off (State 0), only set to “low” so I changed the state payload to reflect this
- I updated the presets to match my possible states
- I fixed the preset mode value template, which seemed to be wrong and caused errors
- I added buttons for pairing and unpairing
- I added
deviceconfig so that everything is grouped together under a single device
Hope this is helpful for someone!
