Qingping Air Monitor	Partly works		PM2.5/PM10 ignored due to μg/m³ unit encoding; local patch exists Saved copy I had the same issue with my Qingping Air Monitor and fixed it locally like this for now: Fix for PM2.5/PM10 sensors being ignored due to "μg/m³" encoding Summary of Bug: The `iaquk` integration currently fails to recognize PM sensors that use the Greek Small Letter Mu (μ, `\u03bc`) in their unit of measurement string. It is hardcoded to only accept the Micro Sign (µ, `\u00b5`). This causes sensors from devices like the Qingping Air Monitor Lite to be "Ignored" in the debug logs despite being correctly configured.

Sensirion SGP41 NOx sensor	Requested		Wants NOx index usable as a source Saved copy … not a duplicate feature request of previous feature requests. ### Is your feature request related to a problem? Please describe. I would like to use my NOx Sensor with this component. ### Describe the solution you'd like Sensors like the SGP41 not only give a VOC Index value but also an NOx Index Value. Maybe this could also be implemented as a Source? It could be treated similarly to NO2. ### Describe alternatives you've considered none ### Additional context This is the documentation of the Index: https://sensirion.com/media/documents/9F289B95/6294DFFC/Info_Note_NOx_Index.pdf Excerpt saved from GitHub on 2026-10-23.
