The gpsd component is using the GPS information collected by gpsd and a GPS receiver.

A requirement is that gpsd is installed ($ sudo apt-get install gpsd or $ sudo dnf -y install gpsd). gpsd uses the socket activation feature of systemd on recent Linux distributions for USB receivers. This means that if you plug your GPS receiver in, gpsd is started. Other GPS device may work too, but this was not tested.

To check if your setup is working, connect to port 2947 on the host where gpsd is running with telnet. This may need adjustments to your firewall.

$ telnet localhost 2947
Connected to localhost.
Escape character is '^]'.

To setup a GPSD sensor in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
  - platform: gpsd

Configuration variables:

  • host (Optional): The host where GPSD is running. Defaults to localhost.
  • port (Optional): The port which GPSD is using. Defaults to 2947.
  • name (Optional): Friendly name to use for the frontend. Default to GPS.
