hass_dsame

Docker container to listen to S.A.M.E weather radio signals via an RTL-SDR adapter and generate a corresponding event in Home Assistant. Relies on the dsame library for generating events presently. Eventually this will be replaced with my own Python code that handles interpreting the data multimon-ng spits out from processing the EAS tones it's fed via rtl_fm.

Must use privileged for execution of the container and pass /dev/bus/usb into container.

Additionally, you must specifiy the following environment variables:

• ACCESS_TOKEN: This is a long-lived access token for your Home Assistant user
• HASS_HOST: This is the URL prefix for your HA instance, for example, http://192.168.1.5:8123 or https://homeassistant.mydomain.com (leave off the trailing slash)
• SAME_CODES: Specify one or more SAME codes for your location. You can look up your SAME code at the NWR website. Separate multiple codes with a space.
• FREQ: Defaults to 162.525 MHz. You should set this to your local radio transmitter frequency, formatted like so: 162.525M. Use the above SAME code link to find the corresponding radio frequency as well.
• EVENT_TYPES: (optional) Defaults to TOR for Tornado. You can also check the NWR website for three-letter codes, space-separated.

You may also specify PPM and GAIN, defaulting to 0 and 10 respectively.

See the example docker-compose.yaml for more.

Many thanks to Mathias for all his help and patience while I tooled and fiddled.

The test version of the source can be mapped to /opt/source.sh inside the container with some options changed to support wideband FM instead of narrow-band. This allows you to test your entire setup using a Raspberry Pi with PiFM to generate the radio signal and ensure your automations will trigger correctly.
