I would like to inform you briefly that there are currently great deals for a Smart Light System called “tint” at Aldi (a german discounter). Tint (from Müller Licht) is compatible with Philips Hue, Osram Lightify and probably also with Ikea Tradfri (and maybe other ZigBee 3.0 ZLL gateways). I have already successfully connected a light bulb (404005) and a remote control (404011) to Hue Bridge.
Attention! The offer is from 28.01.19 and there are still remaining items available.
