Anyone using Xiaomi/Honeywell Natural Gas Sensors?

Is anyone using Xiaomi/Honeywell Natural Gas sensors? I think I am getting false positives from mine. It went off (which was very concerning) and I then purchased two different gas sensors which both say that there is no gas detected. I’m wondering if they are malfunctioning or if there is some sort of calibration that is needed or some other step I may be missing.

I’m (trying) to use one now. Which integration are you using for it? I think mine is bluetooth one.
