I also use this sensor. There are two very similar models: the older Aqara WSDCGQ12LM and the newer T1 th-s02d.
I have four T1 version sensors. I’m also experiencing a problem with randomly displaying atmospheric pressure. I don’t understand where the problem lies. Does the DDF correspond to this model?
I applied an offset of 23 to the four sensors, which is the problem I noticed with a Netatmo weather station. So, I no longer display 10 when the error appears, but 33.
Below are my recent readings: all the sensors are affected by the problem; 22 out of 55 readings are incorrect. I don’t see any threads online indicating that this pressure sensor is defective.

If I look at the requests on lumi3, the pressure is 33. On RealVNC it is 1005
The DDF for T1 th-s02d is xiaomi_th-s02d_t1_temp_hum_sensor.json
Isn’t the error here:
for pressure:
Item.val = Attr.val + R.item('config/offset').val
for pressure_bis:
R.item('state/pressure').val = Math.round(Attr.val / 100) + R.item('config/offset').val
I changed pressure_bis from Math.round(Attr.val / 100) to Attr.val
Edit : Test running since 5 hours without error…
