Hey everyone, I’m diving into the world of home automation and have been exploring the BME280 sensor integration in Home Assistant. It’s been a fascinating journey, but I’ve encountered an interesting challenge that I’d love to get some feedback on.
I successfully added a BME280 sensor to my setup, which measures temperature, humidity, and pressure. However, I noticed that the temperature readings were consistently higher than expected. Following the guide in the Home Assistant documentation, I added a delta_temperature adjustment to my configuration. This brought the temperature readings into line with other thermometers in my home, but I was surprised to see that it also affected my pressure readings.
The pressure readings stepped down when I applied a more negative delta temperature adjustment and jumped back up when I reverted to a less negative value. This behavior is quite unexpected, and I’m curious if others have experienced similar issues or have insights into why this might be happening.
I’ve tried adjusting the delta temperature multiple times to see how it impacts the pressure readings, and the changes are consistent. It seems like the pressure sensor is being influenced by the temperature calibration adjustments. I’m wondering if this is a limitation of the BME280 board itself or if there’s a way to isolate the temperature correction to avoid affecting the pressure readings.
Has anyone else encountered this behavior? I’d love to hear if there’s a workaround or if this is a known limitation. It’s been a great learning experience, and I’m excited to see how others have tackled similar challenges in their setups. Thanks in advance for any insights you can share!
