This project provides to be a guide for the control of the RST01BL bluetooth light bulb and its integration with Home Assistant

Prerequisites

We need to follow the next steps before use the bluetooth bulb.

• Identify the bulb address (XX:XX:XX:XX:XX:XX). You can use NRF Connect o similar.
• Install the pexpect library, ‘sudo pip install pexpect’.
• Install gatttool

How to use

Turn On

From python script:

1
> sudo python start-light.py XX:XX:XX:XX:XX:XX

From console:

1

> gatttool -I
> connect XX:XX:XX:XX:XX:XX
> char-write-cmd 0x0043 CC2333
> quit

Turn Off

1
> sudo python stop-light.py XX:XX:XX:XX:XX:XX

From console:

1
2
3
4
> gatttool -I
> connect XX:XX:XX:XX:XX:XX
> char-write-cmd 0x0043 CC2433
> quit

RGB Color

We’ll use 14 hex digits to change the color following the next pattern:

1
56 XX XX XX 00 YY AA

• The XX XX XX indicates the values of R(Red) G(Green) B(Blue) in HEX. So if we want a red color we should indicate the value FF0000

• The YY indicates if we want color (F0) or white ligth (0F). If we choose the white ligth value (F0) the XX XX XX value will be ignored.

Examples

• Turn on

  char_write_cmd 0x0043 CC2333
