I like simplification. Initially I planned on using a tablet, but I quite like 'physical'.
I've had one of these in use for 2 years maybe? Don't recall. Works awesome, I paid about a tenner. Use the dry contacts with either a fibaro or a nodemcu, can use either a "code entry" to disarm, or touch it with one of the massive bag of included rfid fobs.
Works a treat. I hate the idea of a tablet to achieve this.
