For my new flat I wanted controllable RGB LED stripes. Problem is, most of the controllable cheap ones only have IR remotes, so the receiver must be in line of sight of the remote somehow. That has several drawbacks: you cannot install it behind some furniture without the receiver sticking out, and synchronizing across several rooms is hard.
My solution was to pick some of the RGB LED WiFi controllers (LW12). These come with a neat Smartphone-App to control them.
However, I wanted to control them with my own home-automation-system, or my own smartphone-app.
