Depends on how HA is installed. As long as you can get access to your server (and not only the HA installation on that server), you should be able to run MagicMirror on a display connected to it.
If I’d do that, is another question. It largely depends on what system you are running and how familiar you are with diving deep into your system, eg. control your (Linux-) installation by CLI.
EDIT: Don’t confuse this addOn here in this thread with MagicMirror itself. These are two different things, and what you need would be an installation of MagicMirror itself.
I used the HA OS image. You would definitely need to install X server, but the question is wouldn’t it be better on some other Linux to install HA in docker?
It depends how deep I would have to dive . The CLI isn’t scary for me, but Linux is not a system I use every day.
I would like to ask if it’s possible to install a button on Magic Mirror to show fullscreen HA after and maybe back to MagicMirror after some time? Have you tried something like that?
Same for me too: how can I use that on HA Supervision?
The command ‘/bin/ash -o pipefail -c apk add --no-cache git nodejs nodejs-npm curl wget unzip && npm set unsafe-perm true && npm i npm@latest -g’ returned a non-zero code: 1
In logs:
Failed to to call /addons/394ad856_magic_mirror/install - The command ‘/bin/ash -o pipefail -c apk add --no-cache git nodejs nodejs-npm curl wget unzip && npm set unsafe-perm true && npm i npm@latest -g’ returned a non-zero code: 1
When I try to install magic mirror add on, the process starts but soon ends with:
"Failed to install add-on
The command ‘/bin/ash -o pipefail -c apk add --no-cache git nodejs nodejs-npm curl wget unzip && npm set unsafe-perm true && npm i npm@latest -g’ returned a non-zero code: 1"
Don’t know if someone can quickly try the above steps and confirm there is a fault somewhere during the installation and its not something I’m missing?
Also is it possible to manually install the files to my HA instance from GitHub without the add on installer?
