This little gadget allows you to connect a 300 MHz, 10 dip-switch remote gate opener to a Raspberry Pi so that you can open a gate with just a few lines of code.
It connects directly to an off-the-shelf gate opener remote (sold separately) and uses a 5V relay for triggering the gate opener and a voltage conversion circuit for powering the gate opener (replacing the gate opener's battery). It requires only 5V power, ground, and a single GPIO pin from your Raspberry Pi.
All the documentation can be found on hackster.io.
Yes! You can buy this kit at different levels of assembly from me on Tindie.
Great! Just follow the instructions in my tutorial to finish assembly of your controller circuit.
- build — Scripts and files for generating the
configurescript. End users shouldn't need to worry about this. - images — Pictures of the finished product
- pcb — Extended Gerber (RS-274X) files for PCB fabrication (at, e.g., OSH Park)
- src — Source code for controlling the gate opener over MQTT (and Home Assistant). For more information, see the instructions on hackster.io.
- src/gate-opener-docker — Files for a docker image you can use to control the gate opener from anywhere.
- Gate_Opener_Controller_Circuit.fzz — Fritzing file containing schematic and PCB layout
- configure — Run this script to generate the
Makefileto install the code.
