Roborock (xiaomi vacuum robot) move away from charger when reaching 80% charge

[red_gooogle]

Hi everyone,

I am trying to preserve the battery of my new robot. It should move away from the charger when the charge has reached 80% and return to the charger when the battery drops below 30%.

The topic: valetudo/rockrobo/state

returns: {"state":"idle","battery_level":93,"fan_speed":"mop"}

I subscribed to this topic on mqtt dash.

The topic: valetudo/rockrobo/custom_command

{ "command": "go_to", "spot_id": "Somewhere" }

Sends the device to the specified pre-saved spot location

The topic: valetudo/robot/command
payload: return_to_base
Makes the device returning to charging station.

I set up the script like this. on receive:

if (event.payload < 31) {
app.publish('valetudo/robot/custom_command',{"command": "go_to",
"spot_id": "No charging"}, false, 0);
} else if (event.payload > 80) {
    app.publish('valetudo/robot/command', 'return_to_base', false, 0);
} else {
    app.publish('messages/alert', 'NORMAL', false, 0);
} 

The else could maybe completely left out?

The script does not seem to work. The payload returns more than the number as I showed above. Maybe that is the problem here? I am very new to this kind of scripting so any help would be appreciated.

Looks like you need to send JSON string instead of plain JS object:
app.publish('valetudo/robot/custom_command',JSON.stringify({"command": "go_to", "spot_id": "No charging"}), false, 0);

Also, why you are sending to "messages/alert" here? I suppose this was copied from examples?

app.publish('messages/alert', 'NORMAL', false, 0);

Seems like a bit of mess in your JS code... It's hard to say without knowing what commands to which topics can be accepted by your device.

Thanks for the quick reply.
Well, here is the list of the possible commands.

I did not know if the else line containing

app.publish('messages/alert', 'NORMAL', false, 0);

was needed for the script to work, so I left it in for the time being as it does not hurt to publish anything, does it?

Also, the received payload from the robot is this line: {"state":"idle","battery_level":90,"fan_speed":"mop"}

Will it work to use this line of script:

if (event.payload < 30 {  

to read out the number?

[Routix.net]

Received payload is JSON string. You can't treat it as number.

Do something like this:
var data = JSON.parse(event.payload);

if (data.battery_level < 30) {

    ...

Cheers, it seems to work. I just need to integrate a cooldown timer so that the robot does not move around every couple of minutes. 

This is my code so far:

var data = JSON.parse(event.payload);

if (data.battery_level > 80) {

app.publish('valetudo/robot/custom_command',JSON.stringify({"command": "go_to", "spot_id": "No charging"}), false, 0);

} else if (data.battery_level < 31) {

    app.publish('valetudo/robot/command', 'return_to_base', false, 0);

} else {

    app.publish('valetudo/robot/state', 'all_systems_nominal', false, 0);

}

I introduced new conditions so the robot does not try to go back to the charger when it's already docked. I think the code is complete for now. Many thanks again, for helping me out @
Routix.net!

var data = JSON.parse(event.payload);

if ((data.battery_level > 80) && (data.state == "docked")) {

app.publish('valetudo/robot/custom_command',JSON.stringify({"command": "go_to", "spot_id": "No charging"}), false, 0);

} else if ((data.battery_level < 31) && (data.state == "idle")) {

    app.publish('valetudo/robot/command', 'return_to_base', false, 0);

} else {

    app.publish('valetudo/robot/mate', 'all_systems_nominal', false, 0);

}

hi, i want to use this code too, but i really don't know from which application 

I should run it. I would be grateful if you could give some tips on how to do it.
