Today I saw this post at Hackaday refering to a RFToy, a cool gadget from Rayshobby.net that might be useful when working with different RF modules out there. There is a cool demo showing how to record signals from the remote control of a typical wireless power socket and playback to simulate the remote. It’s the same guy that has written about using Arduino to interface with off-the-shelf wireless temperature, humidity, rain, and soil moisture sensors. I think this gadget can be very useful for me while experimenting with remote sensors for my weather station. I’ve ordered one.
