JTK – Notes and Ramblings Things we have found …


Update to LaCrosse weather

Filed under: General,Home Automation,RTL-SDR — taing @ 5:51 pm

While these updates were made a while ago they weren’t documented. In the original post on the LaCrosse Weather station, rtl_433 sends mqtt data to our openhab server. On github we found a simple means to get rtl_433 to run as a service.

The core is to update /etc/rtl_433/rtl_433.conf. There is a sample file at conf/rtl_433.example.conf. Most important is the output mqtt... line for example:

output mqtt://jtk-openhab,devices=rtl_433/garage[/model]

If the Pi has multiple dongles you will also need to confirm the device line. Then create /etc/systemd/system/rtl_433-mqtt.service:

Description=rtl_433 to MQTT publisher

Enable the service with systemctl enable rtl_433-mqtt.service.
