Automation of gate with ESPhome and sensor

ESPHome
1

Hello,

I am new to this and apologize in advance if there is a topic on this( if there is please guide me to it)

I have a situation, where i live we have at the entrance of the road a gate, that is operated with normal RF remote.
What i want to create is some king of sensor with EspHome as a reciver and the other sensor to glue on the windshield of the car, so when you are close the EspHome board witg sensor to register the transmitter from the car and send an inpuls signal, that will trigger the gate to open.

Is what i wrote possible, i need some guidance where to start with this?

Thank you.

Bluetooth can be used. I’ve thought it may be possible to use the cars Bluetooth from radio

ESP has ble monitor that may be used to watch for Bluetooth devices

License plate reader is possible. You can connect camera to esp

Another alternative: Assuming your RF receiver on the gate isn’t rolling code (most aren’t unless they’re pretty new), maybe you don’t do anything there. Instead, build something to keep in the car, powered by the car, which has a GPS module and an RF transmitter that you can geofence to the area near the gate.

I drive a Tesla and they have geolocated Homelink. I use that for my gate, which effectively does just this when I approach it. The hardest part for you would be programming the signal to match the receiver, at least that’s how I view it.
