MySensors Controller, OpenHAB, RaspberryPi & MQTT

Smart Home Our Smart Home primarily consists of scratch built, MySensors components. “MySensors is an open source hardware and software community focusing on do-it-yourself home automation and Internet of Things” I started off using a single Z-Wave binary component and USB stick, but realised it would be expensive to scale and still not do everything I wanted. MySensors components are build using cheap Arduino computers and standard electronic components. Time & effort is all that is required to piece things together. MySensors Controller While the MySensors MQTT Gateway acts as…

MQTT Gateway

I choose an MQTT gateway over an Ethernet one so it could be connected to the network anywhere in the house and not be tethered to a specific device. Built using instructions at MySensors. Parts include: Arduino Nano NRF24L01+PA+LNA wireless module W5100 LAN Ethernet Shield When I originally wanted to add MY_SIGNING_SOFT, there wasn’t enough memory available on the Nano for that and the MQTT code. Answer: trick the Nano into thinking it’s an Uno and it frees up more memory. My experiences and more information available in the MySensors…
