Set up DHT22 sensor

First, I had to find out exactly how to wire the sensor to the Raspberry Pi 5 – but then the problems really started, as I received the error message “Python modules not installed” in the indi-allsky software. Here I’ll show you how to wire the DHT22 and get rid of the error message in indi-allsky!

Hardware info: Raspberry HQ camera and DHT 22 sensor

For my Allsky project, I rely on a powerful camera unit—originally the Raspberry Pi High Quality Camera with M12 mount, but now replaced by the significantly more sensitive ZWO ASI678MC—combined with a DHT22 sensor for reliable temperature and humidity measurement. This combination provides robust sky images and, at the same time, precise climate data, which is essential for stable operation under changing weather conditions.

Installation of indi-allsky on the Raspberry Pi 5

Since I have only found a few complete instructions, I will describe here step by step the installation of the indi-allsky software as I have done it. These instructions are aimed specifically at users of a Raspberry Pi and are based on the indi-allsky documentation. This is available on github in the corresponding repository. The instructions refer to the largely automatic process, how exactly the manual installation is carried out can be found in the indi-allsky wiki on github. For the Raspberry Pi 5, the automatic installation went smoothly.

Why I chose indi-allsky as the software for my Allsky camera

There are many software solutions that offer different functions – essentially…

Howto: Securing the Raspberry Pi 5

However, as with any internet-enabled device, protection against potential attacks is crucial. Here are what I consider to be the most important measures to ensure the security of a Raspberry Pi 5:
