I'm planning to implement the system using ESPHome so I can easily integrate the sensors into Home Assistant for other purposes, but I want to have a physical keypad and can't find a neat way of doing this with ESPHome. <br /><br />Your Honeywell Galaxy keypad implementation looks perfect for my case. There's an existing wired keypad that I could replace with a Honeywell one with the RS485 back to the central ESP32 to receive keypresses/send screen text. Whilst I am comfortable with the hardware stuff and ESPHome, I have no idea how to implement your keypad library in ESPHome to receive the keypresses and send text to the display. Is there anything you could point me towards to help me achieve this? <br /><br />Thank youAnonymousnoreply@blogger.com
