I have a backup internet connection (using LTE modem and a mobile carrier) for when the main ISP goes down for whatever reason. And respectively I have a fallback URL accessing my HA instance.
Would be great if there is a fallback server option in the Companion App. Basically probing the main server address and if it responds, great. If it doesn’t however, automatically switch to the fallback one. All this ideally should be hidden and automatic.
