Hello,

after implementing and testing successfully the schedule.wpi script, I found today, that the Raspberry Pi didn't executed a script after booting this morning...in the lab it worked fine, in the field not. The only difference between lab and field I can see so far is the temperature. I didn't set any temperature actions on the Witty Pi, but maybe there is a default temperature range for its operation? I think the Raspberry Pi can also boot at low temperatures in this range, but I will verify this in a climatic chamber or freezer.

Did anyone else see possible temperature issues with the Wiity Pi on a Raspberry Pi?

Many thanks in advance for any hint!

Oliver

-5°C is not very low temperature, and Witty Pi should work just fine.

Can't guess what happened without more information though.

The wittyPi.log file should be the first thing to check.

many thanks already for this information, then I can exclude the temperature and will check the log file as soon as I bring the device back from field.

Greetings and have a good day!
