This is my first home automation project (but not my first with Raspberry) and I had some catching up to do when it comes to the knowledge. From I had switched to a Busware-COC and so my intertechno IT1500 sockets. The COC but was too good for this greenhouse project and should be replaced by the above transmitter. The biggest problem was to send the correct InterTechno codes! The commissioning of this transmitter was really easy! I've been using for the software rcswitch-pi of domfi as they can be found at github.
