I wonder if there any devices that send Zigbee message when circuit is closed. I have wired doorbell hooked up to transmitter which triggers doorbell receiver.

I wonder if there any devices that send Zigbee message when circuit is closed. I have wired doorbell hooked up to transmitter which triggers doorbell receiver.
I would like to get phone notification but don’t want to mess with doorbell or ringer. I thought about receiving the transmission with SDR. But splicing in another transmitter might work. I wonder if there are Zigbee alarms.
- btreecat 3y agoYeah, the door/window sensors work this way. Just desolder or clip the reed switch and replace with button or switch or pressure pad.
