Use a Raspberry Pi to turn your HDHomeRun into a wireless device
1 - follow these instructions to turn your Raspberry Pi into a WiFi bridge: https://willhaley.com/blog/raspberry-pi-wifi-ethernet-bridge/
2 - use udpBroadcastMsgForwarder.py to forward device discovery (multicast UDP) messages to the HDHR so that other computers running the Kodi HDHomeRun add-on or HDHomeRun software can find the HDHR. To run the script:
$ python3 udpBroadcastMsgForwarder.py
3 - enable the script to run automatically at boot:
$ sudo cp UDPmulticastForwarder.service /etc/systemd/system/UDPmulticastForwarder.service
$ sudo systemctl start UDPmulticastForwarder.service
$ sudo systemctl enable UDPmulticastForwarder.service
after reboot, check the output via:
$ journalctl -u UDPmulticastForwarder.service -b
