TecnoAlarm is a house alarm system. The input devices are communicating with the main node of the system via an RS 485 bus. In order to be able to plug in such systems in a house automation system, its communication protocol needs to be reverse engineered.
Expected deliverables: an open source library implementing the protocol
Warning: this may take several hackweeks to get something useful

Count me interested, even if I'd prefer a reverse engineering of the TCP/IP protocol instead of the RS Bus since its OOTB functionalities are quite usable for simple home automations projects (currently using it to power on/off appliances, lights, home heating).

@psychowood, I planned on the RS Bus because my installation is rather old TP14 and doesn't have TCP/IP module

Hi all, someone know if there is some "legal constraint" on doing it at "educational purpose"? i own a tp4-20, my idea on hardware side is to connect rs485 port to arduino/esp8266 to bridge serial protocol over TCP/IP then try to log+reverse protocol and create an adapter for HomeAssistant. Ciao
