I would like to be able to control my light in the apartment depending on the daylight. What kind of sensor do you use for this? A daylight sensor that is suitable for outdoor use?
I find the Homematic IP (HmIP-SLO) interesting. However, I would like to clarify in advance if it works with my setup. Something with ZigBee would also be good. Really cool would be a free REST service on the Internet, which provides such data.
