I thought I already posted this problem, but...I can't find the post, maybe I was sleeping when I did!

I have about 20 temperature sensors (all MQTT and I see that the SubType is LaCrosse TX3.
Sometimes it happens that a sensor go crazy and display a completely wrong temperature and never restore to the correct one.
For example a sensor is displaying since 38° while the MQTT message is sending a correct value of 19°!
This happened before, I had to delete the sensor and create a new one, but since the IDX of the sensor is nested into Node Red, it's not so easy to do it every time and...well, I would like to know why this happens!
Any idea?
