mg6250_mqtt: decoding Paradox MG6250 serial events

mg6250_mqtt reconstructs part of the Paradox MG6250 alarm console's serial event protocol. It documents frame lengths, event fields and CRC-16/MODBUS checksums, and provides a Python test client plus an ESP8266 sketch that forwards decoded events to MQTT.
