OJ Electronics Gem

This gems connects to the OJ Electronics cloud service for floor heating thermostats. It uses the long-poll notification based model to keep information up to date with minimal resource usage. Schluter DITRA-HEAT thermostats are also supported.

An MQTT bridge is provided to allow easy integration into other systems. You will need a separate MQTT server running (Mosquitto is a relatively easy and robust one). The MQTT topics follow the Homie convention, making them self-describing. If you're using a systemd Linux distribution, an example unit file is provided in contrib/oj_electronics_mqtt_bridge.service. So a full example would be (once you have Ruby installed):

sudo gem install ojelectronics
sudo curl https://github.com/ccutrer/ruby-ojelectronics/raw/main/contrib/oj_electronics_mqtt_bridge.service -L -o /etc/systemd/system/oj_electronics_mqtt_bridge.service
<modify the file to pass the authenticatin information>
<If you use MQTT authentication you can use the following format to provide login information mqtt://username:password@mqtt.domain.tld >
<Make sure to change the "User" parameters to fit your environnement>
sudo systemctl enable oj_electronics_mqtt_bridge
sudo systemctl start oj_electronics_mqtt_bridge
