Internet of Things


I really enjoyed the idea of having a single light per room, and having it constantly adjust automatically, to never bother, but always fulfill the needs. Small improvements that could save some bucks -lamps are expensive-, and a small flat much more cozy.


Basically starting from a Raspberry Pi, and drawing based on the pros and cons, and needs fulfilled by these gadgets. A good deal for some Hue and here you either buy a proprietary hub and end up using 10 different applications based on the compatibility... Instead, OpenHab acts as a local control server, orchestrated by NodeRed, to organize the logic of multiple scenarii.

To replace all kind of ZigBee hub, DeconZ provide hardware with good compatibility with this deployment, so the setup includes a Phoscon 2 from them.

MQTT v1 is handled using Mosquitto, and MQTT v2 uses the internal OpenHab broker. A few NodeMCU as programmable ESP, easy setup using Tasmota and scalable deployment using templates. Flashed SOnOff relays make good training, cheap and accessible to beginners.

MotionEye is a try, cameras don't always have a good point, moving sensors mostly do the job. A refurbished laptop webcam hooked on a Raspberry Pi Zero W is at try!
