I bought a so called Lampster a couple of years ago in a Kickstarter campaign and it finally arrived. The Lampster is a small scultpture with a lamp as its head.
The lamp itself if great, but the app to control the lampster is really bad in terms of usability.
I reverse engineered the protocol so I can control the lampster using a Raspberry Pi and probably write my own smart home integration later.
To use these commands you need a linux computer with bluetooth and bluez (linux bluetooth stack) installed. If you use a raspberry pi 3 or raspberry pi 4 this should work out of the box.
bluetoothctl
scan on
exitgatttool -I -b XX:XX:XX:XX:XX:XX
connect
Once connected use the following commands.
| command | mode description |
|---|---|
| char-write-req 0x0021 c0 | turn it on |
| char-write-req 0x0021 40 | turn it off |
| char-write-req 0x0021 a8 | activate RGB mode |
| char-write-req 0x0021 c8 | activate WHITE mode |
| char-write-req 0x0021 28 | activate OFF mode?!? |
Once you are in WHITE mode you can adjust the warm white and cold white LEDs with this command:
| command | description |
|---|---|
| char-write-cmd 0x0025 WWCC | WW for warm white LEDs, CC for cold white LEDs |
The values seem to be Hex and range from 00 to 64 (0 to 100%)
| command | description |
|---|---|
| char-write-cmd 0x0025 0100 | lowest warm white intensity |
| char-write-cmd 0x0025 6400 | highest warm white intensity |
| char-write-cmd 0x0025 0001 | lowest cold white intensity |
| char-write-cmd 0x0025 0064 | highest cold white intensity |
| char-write-cmd 0x0025 1E1E | both 30% intensity |
| char-write-cmd 0x0025 6464 | both full intensity |
Once you are in RGB mode you can adjust the colors with this command:
| command | description |
|---|---|
| char-write-cmd 0x002a RRGGBB | RR for red LEDs, GG for green LEDs, BB for blue LEDs |
The values seem to be Hex and range from 00 to 64 (0 to 100%)
| command | description |
|---|---|
| char-write-cmd 0x002a 010000 | RED lowest intensity |
| char-write-cmd 0x002a 640000 | RED highest intensity |
| char-write-cmd 0x002a 000100 | GREEN lowest intensity |
| char-write-cmd 0x002a 006400 | GREEN highest intensity |
| char-write-cmd 0x002a 000001 | BLUE lowest intensity |
| char-write-cmd 0x002a 000064 | BLUE highest intensity |
| char-write-cmd 0x002a 1E1E1E | all 30% intensity |
| char-write-cmd 0x002a 646464 | all full intensity |
