Hello Every Body I search a project with use invisible light beam as detector sensor like this
https://www.amazon.com/Invisible-Barrier-Detection-Infrared-Waterproof/dp/B07P65M7Y9
Some one try somethink like that or use it on Home assitant
It requires 12 to 18V DC to power it and has voltage free relay output contacts. So you can connect it to anything. Also available cheaper here: https://www.aliexpress.com/item/32226426387.html
What sort of sensors do you have now?
Zigbee, zwave, rf, wifi?
Wire the output contacts across the reed switch of any door/window sensor and you’re done.
Hello Tom_i Thanks for your reply
I have Zigbee zwave and wifi
Then you are spoiled for choice. Pick a binary type sensor you are familiar with.
