Airthings BLE pressure differs significantly from other pressure sensors, including itself

[jakllsch]

The problem

The airthings_ble integration displays a significantly different pressure reading than the airthings cloud integration does for data coming from the same Airthings Wave Plus device. The airthings integration reading matches what the Airthings Android app shows, as well as what the Home Assistant Companion reading from my Android phone (generally in the same general vicinity) shows.

It's also annoying that both hPa and mbar are being used as units when they are identical, yet are being graphed separately. Is mbar supposed to be Mean Sea Level Pressure and hPa supposed to be locally-apparent pressure? If so, the airthings integration should be switched to hPa or should convert to MSLP; if not, everything should be in hPa and airthings_ble shouldn't try to convert to MSLP in mbar.

My altitude is about 1000ft/300m, which seems to match the difference shown in these graphs.

Hi, thanks for reporting this. This will be fixed here:

https://github.com/Airthings/airthings-ble/pull/32

This gets fixed in two days while the bogus battery level reporting has been ongoing for months!!? My AirThings Plus has been running fine for a week with 0% battery remaining!

My AirThings Plus has been running fine for a week with 0% battery remaining!

The battery issue was fixed a while ago, but not released yet. This issue was fixed before it was reported here, but also not released yet. There will be a bigger release soon with all the fixes, cleanup etc. We need more testing before we can release since it changes a lot code.

@def1149 please stop bringing up your issue everywhere. This is not relevant to this issue.

Some issues are difficult, some are unsolvable and that's something we have to deal with. All that we ask from you now is a bit of patience. Thanks.
