Multiple "Mirrors" from a single device

@BKeyport
isn’t this to run two MM’s on a single display and have the second MM displayed from the 1920th pixel on the x axis?

I’m wanting to run two MM’s, each instance on isolated displays - one on the display connected to the host in the traditional method and the other on a remote display like another computer, or TV with an in-built browser.

@DarrenO-0 and what does the status say?

pm2 status
pm2 logs 1 (or whatever the number is of the line for the second ) --lines=xxxx
where xxxx is the number of the most recent lines in the log for that app

I have lots of apps on my desktop pm2
pm2 status output

the count under the circle coloum is restarts of that app

@DarrenO-0 the server side still provides access regardless of where the local display output is configured

AND if you run server mode, then the config for the local electron isn’t used

@DarrenO-0 said in Multiple "Mirrors" from a single device:

or TV with an in-built browser.

just heads up…

we use the latest Javascript language options
most/many/all TV’s do NOT have this browser version available and cannot be upgraded.
so the MM screen will be black (browser crashed)

when I got here in 2017, I could run MM on my Samsung TV browser
not anymore

@sdetweil
after running the mm2.sh script (runs as “npm run server”) and then I initiate a new SSH to the MM, I still only see a single instance (the original instance from mm.sh) of MM running when I issue a pm2 status command.
Although I can physically see the second MM displayed as desired in my browser, I’m not seeing the second instance via the pm2 status command.

@sdetweil
Fair enough.
So i’ll have to have a physical computer like a Pi, NUC or MiniPC attached to the TV via HDMI to display the MM via that computer’s browser.
Not a big deal as the TV would be used for viewing TV channels and online streaming content anyway.

@DarrenO-0 how did you add it to pm2 . just doing mm2.sh doesn’t

pm2 start xxxx
xxx is the mm2.sh
or the MagicMirror2.json
it should run and you should see with status

then pm2 save so that it will be saved to the bootup start list

@sdetweil
yeah, I started it via the mm2.sh script that had the “npm run server” command
I’ve now started the second instance as “pm2 start pm2_MagicMirror2_new.json” and “pm2 status” does show both instances running.
Ran “pm2 save”, rebooted the host and both instances are showing as expected - MM#1 on the display connected to the host device, with MM#1 and MM#2 via a browser on a remote device/devices.

@DarrenO-0 Ahh, gotcha. Yes, this is for two on the same system, which linux treats as one huge monitor.
