Roborock S7 - Command to auto-empty in Dock

[serotonie]

Hi,

I have the S7+ (with auto-empty dock) and i'm looking for the command to start the emptying.

Could you guide me in the process of reverse engineering it (if the command is not allready known) ?

Thanks for the great work !

Don't think all commands are all documented yet, but the known (to me) commands for the S7 are

I would start with testing e.g. set_dust_collection_mode

The simplest way to reverse engineer is to install a hacked mihome app, (e.g. vevs version) that can log the commands send to the device. Then e.g. start your emptying in the app, and then check what commands were used. You can than replay those commands with other apps (e.g. openhab/python-miio etc)

I'm trying to figure this feature out too. Looks like I'm now gonna look into this hacked app route.

[exeljb]

After some more googling, i found it... app_start_collect_dust starts the auto-empty and app_stop_collect_dust stops it. Found the info from this page here > https://giters.com/rytilahti/python-miio/issues/1107

edit: also wanted to note that the dock turns off after about 20 seconds after it receives the start command

[rytilahti]

The feature has also some configurable parameters, see the set_ methods in this PR: rytilahti/python-miio#1188 - to summarize:

• set_dust_collection_switch_status with {"status": 1/0} can be used to enable/disable the feature
• set_dust_collection_mode with {"mode": 0-4} can be used to control the behavior. 0: Smart, 1: Quick, 2: Daily, 3: Strong, and 4: Max (whatever those descriptions mean :-)

[marcelrv]

yes, seems indeed i did not include the app cmds... but I think you got it now incl the parameters
"app_sdp",
"app_ice",
"app_start_collect_dust",
"app_stop_collect_dust",
"app_url",
"app_vesion_info",
"app_start",
"app_pause",
"app_stop",
"app_spot",
"app_charge",
"app_rc_move",
"app_rc_start",
"app_rc_end",
"app_zoned_clean",
"app_goto_target",
"app_wakeup_robot",
"app_get_locale",
"app_segment_clean",
"app_get_init_status",
"app_stat",
"app_get_status",
"app_rc_stop"

[serotonie]

It's working flawlessly with app_start_collect_dust and app_stop_collect_dust.
I also could test set_dust_collection_switch_status with succes.

Now I still have to find why the robot is disconnecting/reconnecting itself when its internet acces is blocked, but it's another subject.

Thanks a lot :)
