Nokeval temperature sensor reader

This is a utility which reads the measurements of a wireless thermometer Measurinator.com service. This works with Nokeval FTR970B and compatible devices.

It can be run as a daemon and an example launchd configuration file is included.

How to use

Easy install for Debian/Raspbian 9 (Stretch)

Open apt-get file in editor:

vim /etc/apt/sources.list.d/measurinator.list

Add:

deb [trusted=yes] http://koti.kapsi.fi/hkroger/debs/stretch ./

Save & run:

apt update
apt-get install nokeval-reader

Edit configs:

cd /opt/nokeval_reader
cp config.yaml.example config.yaml
vim config.yaml

Add key where it says <key here> and client id where it says <client id here>.

And start the service

systemctl start nokeval_reader
