At work we have a gate with a centsys centurion motor system (https://www.centsys.com/)
Up until recently it was open during working hours but the site operators now are keeping it closed. This is hugely annoying for our lab as we get frequent customers and deliveries so we're constantly having to get up and walk across the building to open the gate.
I believe the centsys system uses a 434mhz frequency. Attached is a picture of the remote internals.
I'm wondering about the best way to develop a system where we can press a button from a distance and get the gate to open.
My thoughts are to use a LoRa set up to transmit a signal to a microcontroller situated near the gate, which would then transmit the correct 434mhz signal to have it opened. I'm assuming I will need two different sets of transmitters as they won't be one size fits all.
I'm also assuming I'll need to try and sniff the correct frequencies from our existing key fobs.
