New temperature sensors in the shed / 2017-12-29

Since the powerfailure that caused problems for the weatherstation computer ritchie and the conclusion that even after the bios upgrade the serial ports kept failing there was no 'inside the shed' temperature.

But this week I needed a better view of the temperature inside the shed as we're using it to keep some meat cool. So I heated up the soldering iron and the heatshrink gun and made a cable with two DS18B20 sensors in it. I decided that if I started on measuring temperatures inside the shed I also wanted the temperature near the roof.

The interesting bit was adding the two sensors to the w1retap configuration. It seems the whole 1820 family of temperature sensors needs to be set up as a 'DS1820' and w1retap will find out how to read it. Resulting configuration:

28F24C5602000054:DS1820:Tempinside:TEMP0:⁰C::
286B545602000031:DS1820:Temproof:TEMP0:⁰C::

and now I have logging of the temperatures:

2017-12-29T16:28:00+0100 Tempinside 2.812500 ⁰C
2017-12-29T16:28:00+0100 Temproof 2.687500 ⁰C

And it helps us to determine when we need to make space in our fridge and move some other things to the shed to keep them somewhat cool.
