Reverse engineering vacumm robot commands (Abir X9 and others)

[wangwillian0]

The DP15 of the Abir X9 allows sending custom commands in base64 that allows using specific features that aren't available in other DPs, from cleaning specific rooms to setting forbidden zones.

Searching for another attempts, I found https://github.com/bennesp/robottino-rs/blob/main/xplorer-rs/src/protocol.rs, from @bennesp. It may be useful for others to build their automations.

Right now I have only confirmed that the payload format and the command to clean a specific room (0x14) is the same . I would guess a lot of other Tuya devices will use the same or a very similar protocol.
