Somfy Pulsar 2ch RTS (wisniowski doors)

[borissov]

I have the mentioned remote control, and it's used to open the garage door of the building, and then with the second button, it opens the garage door of my individual parking space. The remote control codes are rolling and encrypted, which leads me to the idea of taking out the control PCB board and connecting it to a NodeMCU using 2 optocouplers. What do you think about this idea? What would be the suitable JSON to send a pulse for a fraction of a second to the optocoupler?
