Yesterday I learned about a nice product development from IKEA called TRADFRI (don’t ask me how it is spoken )
These bulbs are talking on zigbee and can be connected with philips hue or osram as I read here (sorry, unfortunately only in German …) https://www.heise.de/make/artikel/Ikea-Tradfri-Das-steckt-im-Smart-Home-aus-dem-Moebelhaus-3597295.html#mobile_detect_force_desktop
here’s a short summary in english http://hackaday.com/2017/02/06/reverse-engineering-ikeas-new-smart-bulbs/
so you can switch the ikea bulbs with hue or lightify - but the other way round you need a gateway which you have to build your own like in the announced link from the above article https://www.heise.de/make/artikel/Ikea-Tradfri-Anleitung-fuer-ein-ESP8266-Lampen-Gateway-3598411.html
Canot wait to get my handy on these
Just wanted to let you know. Maybe you are interested and share your findings if you get these too.
