Hi All!
I've just finished this tutorial about making a remote controlled plug temperature controller;
Unfortunately it's not working and I can't seem to find a solution online 
The remote I'm using is slightly different to the one in the tutorial, so I'm guessing that may be where the problem lies. The one I'm using uses a 433mHz ev1527 - 3000 chip (at least that's what it appears to say on the tiny smd chip).
The RCswitch library appears to support ev1527 chips, so I was hoping it wouldn't be a big deal to use; the code is triggering the LED on the remote, but it's not switching the plug 
I'm using pin 4 TXD / DOut on the ev1527 but poking around with the scope pin6 is also sending a pulse when the on/off is manually pressed (maybe the code overwrites this?).
Has anybody got an idea what I should try? Thanks very much in advance

That should be a big clue! You do have more than one, don't you?

Hi Paul, thanks for the reply!
Well, I'd assumed inside the wireless plug socket would be a similar receiver, but possibly I'm wrong about this? It 'just worked' in the tutorial without having to open up the plug (& I'm slightly hesitant to open up something that will be connected into mains).
I was thinking my next step would be ordering an arduino wireless receiver module and figuring out exactly what was being sent by the controller, but maybe I should just bite the bullet and open up the plug and see what's happening there.
Is this what you'd do?
Thanks again for your help!

I would have started there.

Thanks again for the reply - I really appreciate any help!
So now I've opened up the plug and found it contains an RX480 wireless receiver containing an IC 480R 1708 (I think)... This then leads to a relay.
I'm a bit confused as to why it doesn't work, as the wireless controller could remotely talk to the receiver before it was connected to the Arduino... I'd assumed the Arduino was just sending a trigger to the switch, which would already be set to the correct frequency? Because it's not working, I'm now thinking the frequency is set in the code? Is that correct?
So now I should either buy another wireless receiver module, or desolder the one I have & figure out what is being sent? And then after that, figure out how to implement that into the code?
Is this the best way of going about it?
