Ikea Light control

Submission by David Webster

"The Koppla system comprises three components, a handheld transmitter,
a
plug in lamp dimmer module and a plug in switch module.

The handset includes a realtime clock displayed via an LCD display and can
control up to 10 modules. The handset can be programmed for specific timer
actions or at random to simulate occupancy. Modules can be operated
individually or in user defined groups.

Communication to the modules is via RF operating on 433MHz so there are no
line of sight issues, but the claimed maximum range is just 25m. So, this
may not sound too exciting, as there are plenty of similar plug in remote
control systems already out there - most without the timer capabilities
though, but the prices are very attractive and cheaper than equivalent X10
devices..."
