DIY Home Automation (Arduino RF Remote Control)

[huotianqi]

Hi, I have a similar remote and I want to do the same thing. But it doesn't really work well. Could you please send me an email at heavengate@hotmail.com and I will let you know what i did, then maybe you could point it out where i did wrong. Thanks in advance.

What voltage does the remote work at? I have one similar and the small little battery is 12v, wouldnt i need a transistor in between the wires from the arduino to the remote so the 5v signal can control 12v remote button signals?

Hi, I have a question(Or for anyone that can answer it). When you say you modded the remote to simulate the button press through the arduino's digital outs; how do you accomplish that?

I guess you just remove the physical button and solder in some wires to one of the microcontroller's pin right? But like how long does the HIGH signal have to stay high to simulate a button press? Also, is there a term for this type of mod or method so I can google it and learn more??

Awesome setup btw!

Could you do an update of how it worked out. would be awesome!

He Stekkkkk,

Ik heb een vraagje....hoe heb je de draden op de print plaat van de zender gesoldeerd.

Nice setup! :)

I made a program that communicated thru the printerport to a PLC (one that controls the light thru impulses). From there I could dim, turn on/off the light + open the door :)

Made a program on my phone (Win mobile) and program on my computer that communicated thru TCP/IP with the server control app

Thx!

At the moment I'm reverse-engineering the remote protocol so I can use a bare 433mhz transmitter instead of routing the whole remote. That would make endless available receiver support. The receiver is just a remote controlled relais, so it can be used to switch anything you can imagine.

[n2thee]

wow, good luck on that :-)

Are you using a 433 MHz reciever to fetch what it's sending?

[Stekkkkkk]

Thx!

No; I looked up the parts used in the transmitter.

I'm currently experimenting with it. If I can't get it to work this way, I'll hook it up to the IC that's on the transmitter board. That's guaranteed succes;)

But I prefer to use a bare transmitter as then I can use it for other protocols too (X10 for example) so I can also control thermostats / dimmers / etc.

The kit I use here contains 1 433MHz transmitter / 3 433MHz receivers.

Buying these kits also is cheaper then buying loose parts;)

[n2thee]

That's really smart :) Good luck!

Hey,

You could use a bluetooth / ethernet shield?

I think that's the most suitable solution.

I've been wondering how to set that sort of thing up for a while, but I want to interface from the pc to the arduino wirelessly. I want to use the RF pieces from sparkfun or something ,but can't decide if I should just make a processing sketch that is always running or if I should make a python program or something like that. Basically, I want to be able to download the code to the arduino, then attach a 9V battery and put it somewhere hidden, but give commands over RF. Any ideas?
