I decided against the use of a reflective surface
Includes
MMM-PIR-Sensor
MMM-Nest
MMM-Remote-Control
MMM-Teslalogger
worldclock
MM-DarkSkyForecast
iFrame
3 iFrame modules to display Roon, the car location Map and the house power display
These 3 use homemade Javascript modules to grab data from the Roon API, Teslamate and EmonCMS respectively
Not sure which subsection to put this in, but this seemed the right place. It may be of some use to people with a MM and a video doorbell
I wanted to have the video from my doorbells (I have 2 on different doors) temporarily show on my MM when someone rung the doorbell.
First attempt was to use MMM-Remote-Control, MMM-Pages, go2rtc and MMM-EmbedURL to show the RTSP video (via go2rtc coverting to WebRTC) using Unifi’s Alarm Webhook feature calling for a page change - The 2 video streams on a hidden page, only shown on the page change call.
This worked in principal, but because the modules on the hidden page kept streaming the video even when not being displayed, the RPi5 got quite hot and the network overhead of the constant 24hr streaming was unneccesary.
The solution was to use a script to do the following:
Unifi alarm webhook calls http://pi_ip:9500/motion
go2rtc starts
Wait 3 seconds for go2rtc to connect to cameras
MagicMirror electron refreshes (/api/refresh) so iframes reconnect to go2rtc
Wait 3 seconds for refresh to complete
Switch to camera page (/api/notification/PAGE_CHANGED/1)
Camera feeds display for 60 seconds via WebRTC
Switch back to main page (/api/notification/PAGE_CHANGED/0)
Wait 2 seconds for page to switch
go2rtc stops
Works perfectly now. RPi stays cool and no constant streaming from camera to MM. There is a few seconds delay before it starts, but that actually works for me because of the location of the MM, the doors and where we usually are in the house.
Hope this helps someone who wants to do something similar.
Happy to answer questions.

Instead of using pages to hide the module, I guess I could use MMM-Remote-Control to enable/disable the EmbedURL module? That would stop the streaming?
The EmbendURL modules only display on demand on a seperate page
what do you mean by separate page?
MagicMirror does not have pages, it has logical groupings of content, some shown together, others hidden (this is MMM-pages, MMM-Carousel, MMM-ModulesGroupsRotation, MMM-ProfileSwitcher, etc)
so even if not shown, some content could still be generated (Embed/iFrame) , they don’t know they are hiddenif you run ps -ef you can see the commandline used to launch each process.
you say you have a 1 gig pi5, but mem reports as 2gig.
but you are over physical, and swapping. which takes cycles.
I would suggest, disabling module at a time
adddisabled:true,after the module:name… line
and rerun to see what the effect is. what are the embed modules showing? active content, graphs, images??
The EmbedURL module shows a WebRTC video. The page is hiddent and called on demand (not regular rotation).
I thought that the module would not continue to stream the video when hidden. I guess this is the problem, since it does continue
@mvrlogins if you stop MagicMirror what is the temp?
It drops to 50C in a few min
I have ordered a fan/cooler
But anyone have any insight into whethere the processes I listed are over running?

I have a new 1GB RPi5 running the latest version of MM, installed using @sdetweil 's scripts
It is running very hot at 84C
I don’t have any cooling hardware and it is not installed in a case, but airflow around is not restricted at all.
The only additional program I have running is go2rtc to stream an RTSP camera feed to an iFrame, but that is on a seperate page (using MMM-pages) that is only called on demand
I have ordered a cooler, but wanted to see if there was something amiss.
