I have just installed Home Assistant Green, and know virtually nothing about this system. (I am not an IT professional!)
I am able to access Home Assistant via a browser on my Mac laptop (using the generic URL), and have installed the Home Assistant apps on my iPhone and Mac, but neither of the apps allow me to access my Home Assistant instance without specifying the ‘server URL’ for my individual HA. (I presume the server in this case is my Individual HA Green?!)
How do I find the server URL? I cannot find anything about this in the documentation or forum posts.
No worries, HAOS is an acronym for HA Operating System and that is what is pre-loaded on a Green.
However a Green is fundamentally a Raspberry Pi so you could also run it on Debian OS using Docker which is one way to easily distribute and run software.
