DS18B20 Temp sensor daten in weewx einbinden auf Raspberry ?

[Andreas Weber]

 Hi there

I have a weewx and Rasperry pi and would like to connect 3 temp sensors DS18B20 and display them on my homepage.

Installation of the 3 sensors on Raspberry is no problem, I have 3 folders for the 3 sensors and sensor data.

Who can show me the way how to go on?

There is a script in the weewx manual, but it cannot be used because there is no query from the DS18B20.

I am not programming and I have already experimented with different code snippets on the internet, unfortunately without success.

The sensor data must be written in a text file and weewx reads out the data.

But I have no idea how to do it.

I would like to be shown the way how it works.


Please help....


A heartfelt thank you

The attached python script will write a file named soiltemp.txt for two DS18B20 Sensors.  You will need to edit the sensor numbers and names to fit your needs.

Agreed, writing to a text file is a start. For Weewx you'll want a driver that brings it in. 

You didn't mention if you have a weather station or not. Weewx was designed to be used with a weather station.

Anyway, you can see how I solved a similar problem here: https://hackaday.io/project/101680-solar-powered-wifi-temperature-sensor-for-weewx
