Now i want to do the same to a friends house and i’m thinking of Neuron M103
I gave up this idea…
I used the new rpi 3+ with a wd120gb ssd and a z-wave usb stick. For light control ikea tradfri with pimatic-tradfri and z-wave with some Door/Window sensors from Devolo. This device has a contact sensor, temperature sensor and lightness sensor included. The final setup will include Fibaro Universal Binary Sensor to add some 1wire sensors and relays for hot water temperature control and maybe a zwave thermostat for heating.
Much cheaper from neuron and almost no wires with zwave and tradfri. Working great so far but time will tell.
