homebridge-valetudo-xiaomi-vacuum is a Homebridge plugin which you can use to control your Xiaomi Roborock vacuum that has Valetudo installed.

npm -g install homebridge-valetudo-xiaomi-vacuum

An entry in config.json is needed.

Example:

{
    "accessory": "ValetudoXiaomiVacuum",
    "name": "<Accessory name, e.g. Vacuum>",
    "ip": "<Vacuum's ip address>"
}

Optionally, you can enable switches for controlling speed modes of the device by adding the power-control dictionary with default-speed and high-speed keys (both mandatory in that case), where the speed preset may be one of: quiet, balanced, turbo, and max.

For a mopping-capable vacuum (i.e. Gen 2 - S50/S55), a mop mode button can be also enabled using the mop-enabled option that is a true/false value. You can skip that option altogether - false will be the default.

Example:

{
    "accessory": "ValetudoXiaomiVacuum",
    "name": "Mo",
    "ip": "192.00.486.259",
    "power-control": {
        "default-speed": "quiet",
        "high-speed": "turbo",
        "mop-enabled": true
    }
}

If running your vacuum using Valetudo RE, legacy-mode needs to be set to true.

Example:

{
    "accessory": "ValetudoXiaomiVacuum",
    "name": "<Accessory name, e.g. Vacuum>",
    "ip": "<Vacuum's ip address>",
    "legacy-mode": true
}

If your vacuum access is restricted with login and password, you need to add a authentication option with the value of <username>:<password> to device's config.

Example for when username and password are "admin" (not recommended!):

{
    "accessory": "ValetudoXiaomiVacuum",
    "name": "<Accessory name, e.g. Vacuum>",
    "ip": "<Vacuum's ip address>",
    "authentication": "admin:admin"
}

Tested on Roborock S50 with firmware v001748 and Valetudo 0.6.1.

I played a little with an idea of setting up a HomeKit camera that grabs the generated Vacuum image and streams it as a video.

Here's how to achieve it:

1. An mqtt broker running on a home server. hmq in my case.
2. Vacuum set up to connect to said mqtt broker.
3. I can't believe it's valetudo running on the camera server, with webserver enabled, running on port 3030.
4. homebridge-camera-ffmpeg installed on the camera server's homebridge, properly configured.
5. Camera added to Home.

homebridge-camera-ffmpeg config:

{
      "name": "Vacuum",
      "videoConfig": {
        "source": "-loop 1 -i http://localhost:3030/api/map/image",
        "videoFilter": "pad='ih*16/9:ih:(ow-iw)/2:(oh-ih)/2',scale=1920:1080",
        "maxFPS": 5
      }
}

• -loop 1 sets up ffmpeg so it's constantly loading the generated png for each frame
• pad filter is set up so it expands the generated png to an 16:9 aspect ratio image so it looks right in Home app, then it's scaled using scale down to 1920x1080
• maxFPS set to a reasonable value; at 1 it was having hard time to start live streaming in Home app; at 5 it's instantaneous

Looks cool!
