Adding a buffer node after the temperature sensor to remember the value might also resolve the issue (and be much less cryptic than add/subtract series of nodes). This would also allow other lines of the display to be updated later without loosing temp display.
i test it with clock (0.5ival) and buffer.
Test runs for about 4 days and no errors on readings.
I see it can be problems, when you use a bigger code with debug mode (too much WATCH Nodes)
then it can be problematic.
your explanation is very helpfull…thank you so much…
