For anyone installing HG on Raspbian Buster via the gdebi package using this method
sudo gdebi homegenie_1.3-stable.4_all.deb
You will find errors with the install and the process halts. It appears that the installed version of Lirc is causing the problem.
To overcome this execute the following in the terminal
sudo apt remove lirc
Once you’ve done this execute this again
sudo gdebi homegenie_1.3-stable.4_all.deb
This should resolve your issue and HG should be available on port 80.
