Turning on/of wall display panel with Home Assistant based on proximity/motion

Configuration
1

Hi all, I am looking at putting in a large format screen (likely 42" or similar) running Dakboard to display family calendar, to do lists, reminders etc. I have come to realise that Dakboard also now support home assistant which is great so can also show some of my entities like CCTV, door locks etc.

However my question for this clever community is how might I use a motion/proximity sensor to turn the screen on and off. The screen will be flush mounted in the kitchen but I don’t want a 42" panel powered on when there is no one in the room. Any bright ideas from the group?

thanks all.

I’m using LD2410C mmwave sensors to detect if someone is around my plain android tablets, and turn them on if they are.

Mine are hooked to ESP32’s, but they are actually standalone (through bluetooth) as long as you give them power.

Hey, did you get anywhere with this - I’m looking to do the exact same thing? Would love to see a pic of your dashboard too?

Depends what you are driving them with.
For example I have the official 7" Touch Screen for the Pi in my Livingroom, it displays data from my weatherflow weather station.

On the Pi I use NodeRed to listen for MQTT messages to turn the screen on and off, and control the brightness.

On Home Assistant I use an automation that sends an MQTT message to turn the screen on when the camera detects a person in the livingroom.

It’s also going to come down to what are using ro provide the video signal to the TV.

Not sure how deep you want me to be.
The LD2410C is a cheap mmWave sensor (aliexpress) that detects both moving and static people inside a 6M, 120° area

The nice thing is that it comes with bluetooth builtin, and is supported as such out of the bow by HA. The only “DIY” thing to is to connect a +5V power supply to VCC, ground to GND, and you’re game. There are multiple threads about it on this forum.
