[Xiaomi Miio] Vacuum: New Sensors report wrong values

[simonszu]

The problem

Since the new categorized entities introduced in 2021.11.0 some sensors for Xiaomi Miio Vacuum robots are reporting wrong values. In the releases prior to 2021.11 there were entity attributes which represented the percentage value which are also visible in the Xiaomi Home app, and said for example "The main brush has 5% of its lifespan left".

Since 2021.11 the new sensor entities report a time value which according to the documentation shows how much time is left from the lifespan of the main brush, or the vacuum's sensor cleanliness. I do not complain that this is not as comfortable as having these values as a percentage, since in that case you could just compare to the values in the app.

What i am complaining is that these values are simply wrong. For example, i recently changed the sidebrush of my Roborock S2. According to the app, the new side brush has a remaining lifespan of 192h (or 96%). According to the sensor values in Home Assistant, the side brush has only a remaining lifespan of 289 seconds, which is an offset error of around 191h.

Same for:

• Main brush. App shows 273h (91%) left, Home Assistant shows 32902 seconds (9.13h): Offset of 264h.
• Filter. App shows 58h (38%) left, Home Assistant shows 36749 seconds (10.2h): Offset of 48h.

I have had the robot for over 3 years and always respected the values in the app as quite accurate, so i'd consider them as the single source of truth. The old attribute way of showing the remaining lifespan had the same values as the app, so this was okay, too. Based on that, i am reporting a bug that the new sensors show the wrong value.

Hey!
Got vacuum.roborock_vacuum_m1s here. For some reason it's just vanished from the list! Only have V1 there, therefore I now don't have any attributes indicating sensors state, nor I have any separate sensors for that...

There's a sting in the logs:
"Unsupported device found! Please create an issue at https://github.com/syssi/xiaomi_airpurifier/issues and provide the following data: roborock.vacuum.m1s"
