Eufy Robovac 35C ESPHome for Home Assistant

README.md

Robobvac 35C Config

Since ESPHome doesn't actually support the vacuum entity type, much less creating one in Home Assistant, we have to make due with the TuyaMCU features offered.

We create a few buttons, a switch, and sensors, as well as selects for setting mode and speed. Then there's a vacuum template file for Home Assistant to take advantage of this.

In the end, you'll have a vacuum entity in Home Assistant that's fully local, fully ESPHome, but not perfectly-so.

Of note: ESPHome team, 115200 is a valid baudrate for (some) TuyaMCUs. The one in the vacuum does not support 9600 baud. Please stop alerting me to this. Tasmota has figured this out already.
