FYI: Fixing the Hostname Format for Dreame L10s Ultra (Valetudo)

Third party integrations

Hey folks,

Just sharing a quick tip (mostly for my future self after the next update breaks things again :sweat_smile:), but hopefully useful to others too.

I had a cryptic hostname showing up for my Dreame L10s Ultra running Valetudo, which was making things messy in my Unifi UDM-Pro.

Here’s how I fixed it:

Steps:

  1. SSH into the robot
    (Assuming you’ve already done this when flashing Valetudo — there are plenty of guides out there.)

  2. Check which config file is being used:
    Run:

    cat /data/config/ava/iot.flag
    • If it contains dmiot, then it uses:
      /etc/dmio/device.conf
    • Otherwise, it uses:
      /etc/miio/device.conf

  3. Edit the config file:
    Open the correct file with:

    vi /etc/dmio/device.conf

    or

    vi /etc/miio/device.conf

  4. Find the line starting with model= and change it to something readable.
    Important: Dots (.) will be replaced by underscores (_) in the hostname generated by your network equipment.

Example from my L10s Ultra:

  • Original line:

    model=dreame.vacuum.r2228o

    → Resulted in a hostname like:
    dreame_vacuum_r2228o_MAC:Address

  • New line:

    model=Valetudo.L10sUltra.DreameVac

    → Hostname becomes:
    Valetudo_L10sUltra_DreameVac

Much cleaner and easier to recognize on the network!

I know this involves Valetudo (which is technically outside the HA ecosystem), but since many of us use it with Home Assistant, I figured it was worth sharing here.

Cheers! :wave:

BTW, if some one happens to know how to change the auto generated System ID, I’d appreciate some hints.

You can change the system ID by adding an environment variable.

I won’t call out the variable name or how to set it because of the disclaimer in the code:
