meteohub.de

This will give me an DC voltage relating to the power consumption. The exact amount is not that critical. I am more or less interested in the on/off times. Another setup would be using a differential pressure sensor to monitor an air filter or a PT100 for temperature measurement.

now i set up a new meteohub with a new sd-card and tried to upload the data and home folder - but the folders are not writeable due to missing authorization.
