I've 3 LYWSD03MMC that report a lot of noise on temperature value, it's a sensor problem or firmware/settings problem?

This is a settings problem. image For some types of sensors it is advisable to disable this option. You did not write what version of LYWSD03MMC and what firmware is used...

@pvvx thanks for the answer, I have disabled the Low power mode and the issue is solved anyway the Hardware Version is LYWSD03MMC B1.5 and the Software Version is 4.7

3 out of 7 devices have started reporting noisy readings after working perfectly for around a year or so.

Temperature jumps by a random amount between 0.3 to 0.5 degC, every 10 secs.

Its suspicious that they were all flashed at the same time, and all started having issues at the approx same time.

I'll take a look at the settings mentioned above.
