I have roborock integration. And if you open that sensor you will find on the bottom drop down menu with attributes values.
From those attributes you can create sensor using helpers.
Is tank full or empty?
Try to trigger some error or empty water tank and try then.
Edit:
Also I test this with custom hacs integration for creating sensors from attributes and when i tested this my vacuum had that error.
And also make sure that this sensor exists in your setup.
I think it is not as I tested this in developer tools. He maybe doesn’t have that sensor, maybe he just copy paste mine.
With new roborock integration sensor name changed.
I don’t know if I explain right (not english native spotted).
The entity doesn’t exist in HA with the Xiaomi integration (but does exist with Roborock official). So I guess the sensor “exist” and I would like to use it .
Ok.
I would suggest to you to remove roborock from xiaomi app completely or xiaomi integration.
Add vacuum just to roborock app.
Remove roborock integration from ha and from xiaomi integration and restart.
When restart is finished add roborock integration to ha. There is new integration and you can use maps with it but you need to install maps separately using hacs.
And this is how this should look like if you have properly integrated vacuum to ha
I think the latest version of the integration has native maps support. Haven’t tried it myself yet, but there’s been a bunch of improvements to the integration in the April release.
I have latest version. And I installed maps from hacs. Look here.
It does need latest version of roborock integration.
It is very well done. Visually is basically the same as it was before it was moved to core integration.
And everything is working fine.
