I’m using a new PR49-24L environmental sensor and generally it’s working well, but the pressure readings are abnormally low. I have it outside near my weather station, reporting values to MQTT via a gateway. The MQTT messages show a “pressure” value of “898” (hPa according to the docs) / 26.51inHg. When I started the sensor up 12+ hours ago, it was reporting 896.
898 / 26.51inHg is way low - my weather station currently reports 30.40, much more reasonable.
Is there something I need to do to calibrate the pressure sensor on the unit?
