Darn humidity

What do you use for logging your temperature?

I use a one wire temp sensor, they are addressable individually so you can poll them using a bit of python code on a raspberry pi, I then shove the data into an influxdb time series database and display it with Grafana.

You can read about one wire sensors and daughter boards for raspberry pi here https://www.sheepwalkelectronics.co.uk/1wire_basics.php

I must do a "howto" on the rest of it one day.

Warmer air rises, so removing the leak(s) at the eves will doubtless much improve the situation. Warm air going out must be replaced by colder, damp air (lower down)?

It usually gets blown in on the windward side using the same gap, this pressurises the barn and it seeps out the leeward side. I used a wooden spill to generate a bit of smoke to investigate the airflow.
