Support for vacuums that use new API

[raress96]

Hello,
Any chance of getting support for STYJ02YM vacuum? (Xiaomi Vaccum Mop Pro/some Viomi models)

I currently use this custom integration to integrate the vacuum in HA and it works getting the state, starting etc, but would love to have the map in HA and also to use the map card so I ca do room cleaning:
https://github.com/nqkdev/home-assistant-vacuum-styj02ym

From what I have read, Python Miio already supports commands to this vacuum but the HA guys don't want to have two different implementations for Xiaomi Vacuums in core. Not sure how the map comes from the cloud for this tho...

I tried using this with the same settings as the custom integration but I just get:
Got exception while fetching the state: No response from the device.
Got error when receiving: timed out

Hi, right now it's not possible, as there is no known way to extract a map from this vacuum

[nordeep]

Seems we can get map name and id by raw_command get_map: miiocli -d vacuum --ip ip --token token raw_command get_map
Response: [{'name': 'Map1', 'id': 1605349421, 'cur': True}]
As far as I can see map name is not at the same format as supported devices have.
By the way. If I try to get map by post {'data': '{"obj_name":"Map1"}'} to https://api.io.mi.com/app/home/getmapfileurl recieved error: {'code': -8, 'message': 'objectname invalid', 'result': None} The same if I try use id as obj_name

UPDATE:
According to https://github.com/marcelrv/XiaomiRobotVacuumProtocol/blob/master/map_v1.md - get_map_v1 return map name as "roboroommap%2255512245%2F1" where 255512245 is deviceID.
Trying with my deviceID, unfortunately, doesn't work:
{'code': -1, 'message': 'no premit', 'result': None}

Any ideas?

I have the same vacuum and would love support for it. If you root it and put valetudo on it. Would it then have support?

[PiotrMachowski]

@nordeep I haven't found any way to get a map from this vacuum. It probably uses a different API to get maps (getmapfileurl requires map name in the same format as get_map_v1).

@X1pheR with valetudo you probably don't need this component :) personally I don't use it, so I don't know how it would work. Maybe someday I will try to do install it.

@PiotrMachowski Trying to sniff traffic between MIHome and Xiaomi API. You are right. As I can see new API - v2 in action.
When I open Vaccum page at MiHome app I can see next traffic:

1. POST to https://api.io.mi.com/app/v2/plugin/get_protocol (3 times)
2. POST to https://api.io.mi.com/app/v2/home/get_interim_file_url
3. GET https://cnbj2.fds.api.xiaomi.com/viomi-device/XXXXUserIDXXXX/XXXdeviceIDXXX/0?Expires=1605553436000&GalaxyAccessKeyId=5811787359989&Signature=Z7bNl7NNPDuh6WUAcIW5fhvHrJc=&t=1605551636378

XXXXUserIDXXXX - My userID
XXXdeviceIDXXX - My deviceID
0 - think my map ID - I have only one map
Expires=1605553436000 - timestamp
t=1605551636378 - timestamp

GET Request has size 13233 bytes. Unfortunately I can't see POST body.
Modified get_map.py script for testing. After trying to GET https://cnbj2.fds.api.xiaomi.com/viomi-device/XXXXUserIDXXXX/XXXdeviceIDXXX/0 getting <Response [403]>

UPDATE:
Successful get map_data.gz - 13233 bytes using modified get_map.py by add sniffed url part"?Expires=1605553436000&GalaxyAccessKeyId=5811787359989&Signature=Z7bNl7NNPDuh6WUAcIW5fhvHrJc=&t=1605551636378" to request.
Unfortunately can't open with roboMapViewer2.5.9-1 - Not in GZIP format error. Have no idea what type of data is it. Can send you if interesting.

UPDATE2:

file map_data.gz
map_data.gz: zlib compressed data

Passed file through zlib-flate -uncompress < map_data.gz > out
out file has 663755 bytes
Now I can see names of my rooms inside out file. Still can't open with roboMapViewer2.5.9-1 even if try gzip "out" file

Nice analysis 👍

You can send this file to my email: piotr.machowski.dev(at)gmail.com

@PiotrMachowski Done!

[nordeep]

Post 'obj_name': 'XXXXUserIDXXXX/XXXdeviceIDXXX/mapID' to https://api.io.mi.com/app/v2/home/get_interim_file_url gives a full url as answer - https://cnbj2.fds.api.xiaomi.com/viomi-device/XXXXUserIDXXXX/XXXdeviceIDXXX/mapID?Expires=1605553436000&GalaxyAccessKeyId=5811787359989&Signature=Z7bNl7NNPDuh6WUAcIW5fhvHrJc=&t=1605551636378

Just need to realize output data format (map_data.gz) and glue all together! 🕺

[PiotrMachowski]

@nordeep "just" 😄

by the way, you can recognize supported map format by first two characters: rr

[nordeep]

@PiotrMachowski I thought you were halfway to solve this problem(this is a joke) 😀
