I have designed a system to arm/disarm my Bosch 3000 series alarm system and also let me know when the system is armed/disarmed. The information is required on my PC which is running an MQTT broker.

I have used a ESP8266 / NodeMCU chip to relay the info and an optocoupler to isolate the alarm panel from the ESP8266 (and vice versur).

I have attached my schematic in the link below and hoping to get any feedback anyone has on it before I commit to building it.


These are the components I plan on using:

OPTO Coupler:
NodeMCU ESP8266:
