Question: Send command to Dreame D9 about xiaomirobotvacuumprotocol

[marcelrv]

the Dreame D9 accepts commands but they use the 'miot' protocol. So they use the same sort of communication/encryption but the commands are differently structured.

See
https://home.miot-spec.com/spec/dreame.vacuum.p2008

It uses service, action and property id's (siid,aiid,piid) to identify the commands & properties rather than the more readable ones you mention. In the above link you can find the right codes for your device.

Openhab has a mapping for your device which covers the majority of available commands.

Thanks, that helped me to find a post from you in the openhab community with an command:
action {"did":"Start-sweep","siid":3,"aiid":1,"in":[]}

I was able to adopt this for my D9:
action {"did":"Start-sweep","siid":2,"aiid":1,"in":[]}

Now I'm working on two questions:
Why do you put the action name in the device id (DID)?

When I want to clean a specific room, what is the syntax to add the rooms to the command? Is it the piid?
action {"did":"start-room-sweep","siid":2,"aiid":3,"piid":4,"in":[]}

The did field appears to be free text, in the sense that the devices don't check if the true did is in it

To ease the reading of the log I enter the intended (readable) command
