Building and Modifying Valetudo

These are instructions for quickly setting up an environment where you can build and modify Valetudo according to your needs.

Please note that working with Valetudo requires at least NPM v7 and Nodejs v15.

1. Clone the repository

cd ~
git clone

2. Install dependencies

cd Valetudo
npm install

3. Create default configuration by running valetudo

npm run start:dev --workspace=backend

On first launch, Valetudo will generate a default config file at the location set in the VALETUDO_CONFIG_PATH environment variable and automatically shut down, because it won’t be able to autodetect the robot it is running on.

The start:dev script chooses ./local/valetudo_config.json, relative to the root of the project, as the config location.

You need to edit the newly created file in order to be able to talk with your robot from your dev host:

  "embedded": false,
  "robot": {
    "implementation": "RoborockS5ValetudoRobot",
    "implementationSpecificConfig": {
      "ip": "",
      "deviceId": 12345678,
      "cloudSecret": "aBcdEfgh",
      "localSecret": "123456788989074560w34aaffasf"

Setting embedded to false disables all functionality that assumes that Valetudo runs on the robot such as some file-system related things.

For a list of possible values for implementation consult the robot implementations in Valetudo is also capable of running without a real robot. The MockRobot implementation provides a virtual robot that has a few basic capabilities. It requires no further implementation specific configuration.

The config key robot specifies the ValetudoRobot implementation Valetudo should use as well as some implementation-specific configuration parameters. When running on the robot itself, these are usually detected automatically.

Vendor Config Key Robot Location Robot Key
Roborock valetudo.conf /mnt/data/valetudo/valetudo_config.json  
  deviceId /mnt/default/device.conf did
  cloudSecret /mnt/default/device.conf key
  localSecret /mnt/data/miio/device.token  
Dreame valetudo.conf /data/valetudo_config.json  
  deviceId /data/config/miio/device.conf did
  cloudSecret /data/config/miio/device.conf key
  localSecret /data/config/miio/device.token  

Since deviceId and cloudSecret are static, you’ll only need to do that once. Note that localSecret might change when you’re switching wireless networks etc.

It’s possible to specify both secrets as either hex or a regular string.

Please note that Valetudo will replace the configuration with a default one if it fails to parse it correctly.

The logfile is also configured via an environment variable: VALETUDO_LOG_PATH and defaults to os.tmpdir() if unset.
To just use stdout in your dev setup, you’ll need

VALETUDO_LOG_PATH=/dev/null for linux/osx and

VALETUDO_LOG_PATH=\\\\.\\NUL for windows hosts.
That’s four backslash dot two backslash NUL if it’s not displayed correctly due to escaping issues.

4. Verify configuration and run

npm run start:dev --workspace=backend

If your configuration is correct, Valetudo should now be working on your development host.

5. Code!

Modify the source code according to your needs, and restart the server as needed – you can always run it as:

npm run start:dev --workspace=backend

7. Build and install on the device

When you’re done with your modifications, here’s how to build the executable for the robot:

npm run build

The output file valetudo is a binary file that you can copy to the device:

scp ./build/armv7/valetudo root@vacuum:/usr/local/bin/

Once you’re that far, you hopefully don’t need any further advice.
