Correlation between Temp warning and TP Connection?

[baggins]

Hi,

I have a LM4 (firmware 20160714) where there is a strange issue.

Very frequently there is an error message in the Error Log : KNX/TP: Temperature Warning. The actual temperature is around 85 °C.
At the same time there is a message in the Alerts: KNX/TP: Connected. There are no Disconnected messages.

What is the relation between the temperature and the TP connection?
I have another LM4 where the temperature is quite similar to this one where I don't get these messages.

Hi
There is no one secret answer but in short this info comes directly from the TP UART chip. In most cases this will happen when there will be lots of telegrams at the same time.  Good practice is to check your scripts and make sure they write to TP only when necessary.  Use grp.update when TP is not needed and grp.checkwrite when writing to TP to not write the same value all over again.  Apply filter if you use more then one IP router.
