NAME

Device::Osram::Lightify::API - API Documentation

API Overview

The starting point for using this module is that you have a hub with an IP address upon your local LAN, which is able to communicate successfully with any installed bulbs you have.

The module itself is responsible for talking to your hub, and sending commands to it to initiate actions, or perform introspection, so you'll need the IP address of your hub available.

Overview

The communication to/from the hub is carried out via short binary communication with the hub over TCP/IP on port 4000.

Light Discovery

To discover the lights which are available to your hub we connect and send the following binary string to it:

0x0B 0x00 0x00 0x13 0x00 0x00 0x00 0x00 0x01 0x00 0x00 0x00 0x00

Once sent we then read back a header. The header contains 11 bytes of reply. From this header we read the 10th byte which will tell us the number of bulbs which are available.

Once we know the number of bulbs we can then read 50 bytes for each bulb, and this block of data can be parsed to show the current state of that specific bulb.

01 - ID byte 1
02 - ID byte 2
03 - MAC Address 1
04 - MAC Address 2
05 - MAC Address 3
05 - MAC Address 4
06 - MAC Address 5
07 - MAC Address 6
08 - MAC Address 7
09 - MAC Address 8
10 - Bulb Type
11 - Firmware Version 1
12 - Firmware Version 2
13 - Firmware Version 3
14 - Firmware Version 4
15 - Online/Offline
16 - Group ID 1
17 - Group ID 2
18 - Status 0 == off, 1 == on
19 - Brightness (0-100)
20 - Temperature 1
21 - Temperature 2
22 - R
23 - G
24 - B
25 - W
26 - Name 1
27 - Name 2
28 - Name 3
29 - Name 4
30 - Name 5
31 - Name 6
.. - Name 15

NOTE The returned 50 bytes are NULL-terminated/padded.

You'll almost certainly want to make sure you can parse this stuff, because users will want to operate upon bulbs by name - and the API only allows you to operate on specific devices by MAC-address, so at the very least you must be able to lookup `NAME -> MAC`.

Broadcast

There are two simple commands which will turn all lights on, or off, these are simple to get started with because you don't need to set the MAC address of the bulb inside the command.

To turn all bulbs on send this:

0x0f 0x00 0x00 0x32 0x01 0x00 0x00 0x00 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0x01

To turn all bulbs off send this:

0x0f 0x00 0x00 0x32 0x01 0x00 0x00 0x00 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0x00

Once sent read back 20 bytes to get your result.

Light-Specific Commands

The rest of the commands are going to be bulb-specific, and involve sending a command with the MAC address of the destination device inside their bodies.

On/Off

To set a specific bulb ON or OFF you need to send the following magic string:

0F 00 00 32 00 00 00 00 NN NN NN NN NN NN NN NN ON

Here `NN` should be replaced with the MAC address of the device you wish to control, backwards, and the last byte ON should be replaced by 0x00 to turn the device off, and 0x01 to turn it on.

Once set read back 20 bytes to get your result.

Brightness

To set a specific brightness for a bulb you need to send the following magic string:

11 00 00 31 00 00 00 00 NN NN NN NN NN NN NN NN XX 00 00

Here `NN` should be replaced with the MAC address of the device you wish to control, backwards, and the byte XX should be replaced with the brighness level you wish to set, in the range 0-100.

Once sent read back 20 bytes to get your result.

Colour

To set specific RGBW values for a bulb you need to send the following magic string:

14 00 00 36 00 00 00 00 NN NN NN NN NN NN NN NN RR GG BB WW 00 00

Here `NN` should be replaced with the MAC address of the device you wish to control, backwards, and the bytes RR,GG,BB,WW should be updated with the appropriate values.

Once sent read back 20 bytes to get your result.
