Noise on lywsd03mmc temperature all 42 minutes

[trunneml]

One of my lywsd03mmc thermometers shows random noise all 42 minutes. Is this firmware related or is it just a defect one?

I use BTHome and M5Stack Atom with esphome as BLE receiver.
HW should be 1.7. but I'm not sure (I have about 10 LYWS in different versions). I will check that when I'm back home on Friday.

ESPHome is not particularly friendly with the only open standard for BLE - BTHome.

I also activated the onboard Bluetooth receiver on the x86 motherboard. All other 5 active Thermostats are working correctly.

It is a HW1.7. Low Power Mode was activated. Display showed the correct value. BLE transimited the 1.6 baseline.
