Tyre pressure same across all tyres #251

Closed MelchMwoan closed 1 month ago

MelchMwoan commented 1 month ago

Good afternoon, I have integrated the python mqtt gateway in Home Assistant for my Marvel R. But it looks like all 4 tyres are reporting the same pressure which I highly doubt is true. And the pressure is changing quite often between 2.2 and 2.6 bar.

Is this expected behaviour?

That depends on what the API reports back to us. For an MG4, during driving, the values change quite realistically

It may be the Marvel R TBox supplies an average value across 4 tyres instead of individual readings (I also see you are lacking one decimal digit of precision)

That's normal, sensors are not battery powered but they are motion activated/powered. When the car is stationary the tbox reports the last reading
