Request: pereodical status update for Home Assistant
Hello!
It's more feature request: could HASS sketch be modified to send pereodical status update to MQTT? Cause you will loose control from "alarm control panel" if HASS will be restarted after power failure (so no arm/disarm buttons).

P.S. 1:
Confirming work on PC1565

P.S. 2:
Also for Wemos D1 R1 (!) actual pins are:
D3 (5), D4 (4), D10 (15)
and board can be powered directly from AUX via Vin

P.S. 3:
what is meaning of 1kOhm resistor in connection scheme to transistor? It's also working without it (accidentally forgotten to add it when was rewiring)
