Klik aan klik uit has released a new transmitter. You can use this transmitter to turn an existing switch into a remote. That means that an existing switch can now transmit a signal that turn on/off (multiple) existing KAKU lights/devices.
Another KAKU product that has been on the market for a while does something different. This is a switch that transmits a signal instead of ‘the-device-behind-a-switch’ that transmits a signal.
UPDATE: Apparently this is not a completely new module. It looks slightly different from the old version. For some reason everybody seems to think this is a completely new product. Maybe they have hidden the old version for a long time or it might not have been very good. Who can tell..
