I built an ESPHome keypad for Alarmo, using a nodeMCU and a TM1638 display, both from Amazon at a cost of about $10. Here is a pic:
Buttons 1 and 2 arm the system; button 3 calls for a PIN to be entered to disarm. The code uses the api to communicate with Alarmo, and could be modified to use other modes. I don’t use arm/disarm codes on my system, so the PIN (here 1234) is used only on the keypad. It could be sent to Alarmo in the data template if you use codes. Here is the code:
