Hi, what I've done in short:

I start a python script via crontab every 10 minutes which reads I2C data
from a BME280 sensor. This script calculates the temperature, relative
humidity and relative air pressure and sends it to a webserver.

This works perfectly.

To be on the safe side I make / made a reboot every night. From this the
questioned machine didn't return, now. I see in the log that the last
transmission was ok, then the reboot was started and the connection was
lost. So, I doubt that the machine completely broke down. Most likely the
SDCard gave up.

So, I also have to re-think if it is a good idea to make daily reboots
even though the resources are not locked or eaten up. Maybe one reboot
per week will also do?

P.S. I'd rather prefer to use "Raspberry Zero / WLAN" only for
installation, since it has only Wifi and the network there is cable based.

Best regards,

Markus
