Hi guys,
I have been thinking for quite some time to kick-off a project and before (hopefully) placing the final order I very much would like a sanity check on the project:
My current situation:
I have a remote-controlled gate to my yard. It uses a coded signal on the 868 MHz frequency to receive the control signals for 1) opening 2) stoping and 3) closing.
Due to the coding of the signal I am most certainly unable to simply record the signal generated by the hand-held remote control unit via a RTL-SDR and use a simple 868 MHz board to broadcast the corresponding signals (e.g. like record and replay Radio Frequency (RF) remote signal)
Intended solution:
Buy an additional hand-held remote controller, program it so that it mirrors my first remote controller, dismantle it and use the board itself.
As it has four physical buttons on it (I am currently using only two of them) I want to activate the buttons via a RPi or Arduino.
The RPi or the Arduino itself is then to be integrated into Home-Assistant using the [RPi GPIO] (Raspberry Pi GPIO - Home Assistant) or the Firmata as a switch that I can then use in any downstream automation.
Does this make sense and sounds doable?
Thank you
