RTLAMR to MQTT Bridge hass.io addon

A hass.io addon for a software defined radio tuned to listen for 433MHz RF transmissions and republish the data via MQTT

This hassio addon is based on biochemguy's (non-docker) setup: https://community.home-assistant.io/t/get-your-smart-electric-water-and-gas-meter-scm-readings-into-home-assistant-with-a-rtl-sdr This addon is based on the addon from jdeath here: https://github.com/jdeath/RTLAMR2MQQT which in tturn is based on James Fry' project here: https://github.com/james-fry/hassio-addons/tree/master/rtl4332mqtt which was based on Chris Kacerguis' project here: https://github.com/chriskacerguis/honeywell2mqtt, which is in turn based on Marco Verleun's rtl2mqtt image here: https://github.com/roflmao/rtl2mqtt

Usage

Install the addon. Do this by downloading this repository and adding in a folder under /addons/ (eg. /addons/rtlamr2mqtt)
Use addon configuration to configure:

mqtt_host
mqtt_user
mqtt_password
msgType
ids

Copy rtl2mqtt.sh to your hass.io config dir in a subdir called rtlamr2mqtt. i.e. .../config/rtlamr2mqtt/rtl2mqtt.sh This allows you to edit the start script if you need to make any changes

NOTE that some people have reported issues using samba to copy the script. For some reason it does not get copied to the container on start up of the addon. If you see this issue, please scp the script to your hassio config folder, or ssh in and edit the file locally with vi/nano.

Start the addon

MQTT Data

NooElec NESDR Nano 2+ Tiny Black RTL-SDR USB
RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio

Troubleshooting

If you see this error:

Kernel driver is active, or device is claimed by second instance of librtlsdr. In the first case, please either detach or blacklist the kernel module (dvb_usb_rtl28xxu), or enable automatic detaching at compile time.

Then run the following command on the host

sudo rmmod dvb_usb_rtl28xxu rtl2832
