Candle - signal Hub - A universal 433Mhz signal detector and cloner
-
The touch screen code is now also available.

Something I had hoped actually works: it can also copy IR (infrared) signals!
Settings need to be slightly different, as IR signals are 'slower' than RF signals. Changes I made to the settings are:
#define MAXEDGES 100 // instead of 400 #define GRANULARITY 100 // the default settings of '50' also work, but IR signals need less precision. #define MAXIMUMDURATION 66000 #define MINIMUMSILENCE 66000It doesn't recognise things perfectly, as IR signals don't seem to repeat themselves in the same way. You may have to press the button a few times before the signal can be copied.
I also haven't tested if transmitting the signals actually switches IR devices on and off.
An example:
00000000 > 0 11110111 > 239 00010000 > 8 11101111 > 247 -
- It can now handle even more 433 signals.
- Slight code simplification

@Homer yes
Thanks, and thanks for your private messages!
I managed to build a rf433 sender which is connected to wifi and is outside of the Mysensors environment, and it works, but I can't get my controller (Vera) to communicate with it. This looks like it should work perfectly for what I want it to do!
Thanks for sharing!

I am having issues with the device I made myself which doesn't use this code, so I have decided to give this project a go. One problem though... I copied the sketch from you link, and even without any changes or alterations, the sketch doesn't compile. It gets to line 468 and says "detectedMessage" was not declared in this scope.

@alowhum I've finished building this. I have also bought a couple cheap window/door sensors to try, but I've hit a snag.
When I joined this to my controller (Vera) it said that it found 2 devices, but when I check my devices I only find one device, and all it says is that it's a node; I have very little in the way of interacting with it. I'm not sure what's going on.... It's weird that it found two devices and only displays one! Seeing that I'm not using any screen, I can't do anything because I thought I could interact with the hub from within my controller. Have I done something wrong?
-
I haven't tested it without a screen myself. I'll look into it for you and see if I can make the code work optimally without it. I'll get back to you with the updated code.

Here is the new version which should work just fine without a touchscreen attached.

I also added a new playlist feature. If multiple replay requests are received in quick succession (perhaps from a home automation rule that wants to trigger multiple sockets), it can remember these requests and replay them one after the other.
-
I've finally finished building this, but sadly it doesn't want to work with my controller (Vera). When I start the inclusion process I'm says that it has found 2 devices, but when the controller finishes setting it up it only ends up showing one device, and all it says is that it is a node.
Has anyone built this and have had success with Vera? If you are using this, which controller do you use?
-
It should not show a temperature sensor, since it doesn't have one. Are you sure it has actually connected? Try listening to the serial output of the node (using the Arduino IDE's option to do this), and check if it says that it has connected ok, and that is is showing you the decoded signals then you play the RF signal. You can even try enabling the debug option to get even more details about the node's state.

Thanks for the reply!
It doesn't show a temp sensor. I circled the device that it shows, but of course I only circled one because the second device doesn't show.
@homer Look at your device list on a computer web browser. It appears that you are viewing it with the Vera app on your phone or tablet. I have seen where some devices don't show correctly on the Vera app. I don't know what type of device it will identify as, but you should see "<some device type> (12)" with the key being the (12) as that identifies the node that presented it. Also, do you have any 433Mhz devices that it may be detecting? Looking at the code a bit, it looks like it will present any 433Mhz devices that it sees to your Vera controller.

@dbemowsk thanks for your reply. Yes the screenshot was taken Vera using my phone, but I only did that as I was using the phone at the time. I went out to have a smoke lol after I tried on my laptop.
From what I understand, it should have created devices that then allow for the inclusion of rf433 devices, but if that isn't the case, I'm happy to be corrected!
