This works well although you have to keep in mind that turning on the screen via CEC takes around 10-15 seconds. The small Zigbee motion sensors I am using I can just use the same events to turn on or off the mirror itself. The doorway that houses the Magic Mirror already has a motion sensor for the lights.
Instead I opted to go for a bit more precise solution and reuse the motion sensors from my smart lights. If you are interested in buying Zigbee devices for your smart home consider doing it via my affiliate links above. Sonoff S26 as a hardware alternative (with Tasmota) or Aqara plug via Zigbee The new schedule helper might be a good tool for this.
The simple idea is to use a time based trigger and simply shut down the screen during the night or maybe when I am not at home. I came up with two different ways of automating the Magic Mirror. # 0 is the TV, 1 is the pi itself - check via echo 'scan' | cec-client -s -d 1Įcho 'standby 0.0.0.0' | cec-client -s -d 1Įcho 'pow 0.0.0.0' | cec-client -s -d 1 The motion sensor As described before the Pi supports this protocol and can send on or off commands like this: # needed
#Best panel for magic mirror raspberry pi tv#
The Pi is connected to the TV via a HDMI cable and HDMI can not only transport image data but also simple commands via a protocol called CEC.
#Best panel for magic mirror raspberry pi software#
Instead I am relying on software and HDMI right now. TVs are not made to quickly turn on or off (takes some time and shows a logo first) so the hardware option only means more hardware that is drawing power but no huge advantage. I see two options here: using a smart relay like the Sonoff S20 I use in my smart light system or software control. To fix this I need a way of controlling the screen itself. I already disconnected all components that are not needed anymore, like speakers, but the panel is still running 24/7.
The Raspberry Pi itself that is running the software part does not draw too much power but a TV can be different. This makes the text appear to be floating in the mirror. Basically it is an old TV screen mounted behind a semi transparent mirror that is showing relevant data like a weather forecast in white on black. I have described how I built my magic mirror before in this article.
