Vacuum robot without cloud – Viomi SE with Valetudo

For some time I thought about integrating an vacuum robot into our smarthome. But as the rest of the smarthome the robot should work offline. So I came across Valetudo Firmware an the list of supported robots: Supported Robots | Valetudo

Next step was, to find a supported robot for a reasonable price. I came across a Viomi SE at an Amazo Warehouse deal in “Good” confition for 150€ so i decided to give it a try.

I followed the detailed description how to root the robot:

Hypfer/valetudo-crl200s-root: Tooling to root CRL-200S-based vacuum robots (github.com)

with one exception regarding enabling the adb access:

To enable adb access it was necessary to press and hold Home Button, press the power button ten times, release both then start the enable-adb.sh script and follow the instructions.

The first few tries did not seem to work as expected:

I switched the USB port on the RasPi and it works as described on GitHub:

Running the shell script:

Extract the firmware:

Run the Install script

And after a reboot of the robot the webinterface is accessible and I was able to controll the robot locally and integrate it via mqtt into home assistant.

Glück Auf!
