The PHP and Arduino code is now available within googlecode github and can be found here:

I’ve had limited time to update this lately, and currently as it stands it fills my needs. I might come back to this at a future point, but for now, if anyone would like write access to the repository to help move this forward, please let me know!
I’ve been working hard on updating the Lightwave RF Control development to take it out of beta.
I’ve resolved a number of issues/bugs, added multiple device queuing to the arduino code and therefore the ability to power off/on an entire room as shown in the screen shot below. This required introduction of another serial message format to pass to the transmitting device from the web application, and an separation of some of the serial code/transmission to help with this. It also required rethinking the UI a little to group controls on the screen better, and introduce (and differentiate) the whole room option where there is more than one device in the room. This transmits a queue of devices to power on/off each device in the room sequentially.
I’m still ironing out the last few bugs, but this should be released soon for anyone interested once I’ve put the ‘sequence’ code together to allow you to create your own sequences!
Due to a few requests, here’s the initial release of Lightwave RF Control!
This release contains two parts
To get this working, you might want to take a look at the write up of the implementation, which details the arduino circuit to put together, and the setup of the php application itself.
The PHP web application needs MySQL, and should create the database on startup, though you’ll need to ensure after unzipping that the ‘config.php’ has necessary write permissions for the web user (chmod 777 the config.php file if you’re lazy like me 🙂 )
The following describes the process and setup of how I made my Lightwave RF device controller, from an arduino, a few components, and a Raspberry Pi.
This post will grow out with more information as I add it, but this in the position now where it’s ready to be put out there.

The following diagram shows a simplified assembly. Note the LCD Serial module is one whole module, just shown as two separate components on the diagram. The transmitter is a 433.92Mhz (called 433 or 434MHz transmitters from various places)
Wired into a breadboard (in a messy way unlike the diagram above) here’s what my prototype looked like:
3 areas of interest are highlighted in the photo
Note – the transmitting LED was not connected here. For prototype, I just relied on the one inbuilt into the Arduino on pin 13
Prototype was tested using the serial monitor within the Arduino IDE by placing a lightwave RF device in pairing mode, and supplied the following command over serial:
#111235190237183123100Lounge*
The format of the message is as follows
| Description | Length | Values | Example | Notes |
|---|---|---|---|---|
| Start | 1 | # | # | Start with a # |
| Transmitted ID | 18 | [0-9](18) | 111235190237183123 | Has to be 18 chars |
| On/Off | 1 | [0/1] | 1 | 1=on 0=off |
| Dim Level | 2 | [00-31] | 31 | 31 = Max 01 = Min00 = Ignore |
| Description | 15 | [aA-zZ] | Lounge | Up to 15 characters – if more will wrap around |
| End | 1 | * | * | End with a * |
Once installation has been completed successfully, you’ll be taken to the setup wizard to add any Lightwave devices you may have:
Step through the wizard to
a) Select or create a room – devices are grouped by room in the user interface
b) Add the receiver (The actual lightwave RF device). Here you add give it a description and select the type of receiver, e.g. dimmer, socket, relay, etc.
c) Following addition of the receiver is to create a transmitter identifier. This uniquely allows the transmitter to be associated with a single receiver, or multiple receivers. For example, you can reuse the same transmitter for a room to turn on more than one device from the same command. You’ll notice in the following screenshot that the final transmitter covers 2 receivers. If you want the control to be unique, just pick new transmitter and enter a description.
d) That’s enough configuration and your room, receiver and transmitter are all recorded and linked. The final stage is to actually pair the transmitter and receiver together. To do this, you need to put your receiver into pairing mode (e.g for a dimmer, hold both buttons. For a socket hold the single button. For relay, push in and hold the pairing button with a pen).
Once the device shows it’s in pairing mode (usually by flashing the lights) you need to transmit a code for the transmitter. The wizard allows you to do this, and then once the receiver confirms a pairing, you can test this with the off/on buttons.
Once paired, finally press the finish button.
You’ll then be presented with the device control screen where you can control your Lightwave RF devices
From here you can select the room, and chose to power on/off the devices, and where the device is a dimmer, you can choose to adjust the dim by clicking or touching the dim ‘gradient’ bar.
If you want to change the setup or reinstall, you can use the menu in the top left corner.
On transmission, it should looks like this!
