Hi all, I'm new to the Jeenode world, and I have one question. Is it possible to use it as a garage remote control?! It uses 433Mhz, therefore, my guess is it will be just a software question right?! Thanks all. Keep up the good work.

It's more than software. Although the RFM12B can send @ 433 MHz - if you've got an 868 or 915 MHz unit, range will be severely limited. One meter / a few feet. It's probably not a good fit for what you may have in mind...

So, you're saying, the problem is distance?! that can be arranged for what I have in mind :|

In that case - sure, try it. There are fs20demo and kakudemo sketches to show how to do this. Should be fairly straightforward with the support built into the RF12 driver library.

Beware of those garage doors controlled @ 433 MHz; advertised as being secure with "rolling code" bla bla etc., but mine opened twice when it shouldn't. This was caused by receiving 433 MHz "noise" (maybe not that strange, with a dozen 433 MHz sensors here, transmitting all day long). This "noise" was recognized as coming from a "learned" remote control and so the garage door opened; I can assure you, this isn't funny at all!
After that, i cleared all remotes from the door's memory and now the garage door can only be controlled by X10. As remote controls i now use 868 MHz security keyfobs. Furthermore the garage door is now equipped with a sensor and as last countermeasure i shut down the complete garage door opener at night and when nobody's at home. The keyfobs can restore power and control the door. Automating the garage door is great, but not when it starts leading it's own life.

@Digit: Thanks for that point of view ;)

I took the coward's way out... I just bought an extra remote opener, and I have the JeeNode trigger the remote with a reed relay in parallel to the remote's pushbutton.
The JN also taps into a commercial door monitor, so I can tell what the door state is.
