Esp Lamp

A simple esp8266 rgb lamp controllable by an TCP API.

How to Run

1. Install PlatformIO
2. Create a .env based on env_example
3. Plug a esp8266 to your computer
4. pio run -t upload -t monitor
   • get the server IP from here
5. Get lamp IP from console or monitor UDP broadcast on port 12345 coming from it with the message "openupitsme"
   • I recommend using wireshark to monitor and get a feeling for it!
6. send 6 bytes through TCP to get color/alter color:

.-----------------------------------------------------.
| length | P or G |pwn_step|   R    |    G   |   B    |
| 1 byte | 1 byte | 1 byte | 1 byte | 1 byte | 1 byte |
`-----------------------------------------------------´

• length - always 6.
• P or G - P to change color and fade effect intensity, G to get these information
  • if G is used, all the other bytes are ignored, but must still be sent
• pwm_step - fade effect intensity. Range from 0 to 100.
• RGB fields - range from 0 to 100 each.

7. receive back

.-----------------------------------------------------.
| length | status |pwn_step|   R    |    G   |   B    |
| 1 byte | 1 byte | 1 byte | 1 byte | 1 byte | 1 byte |
`-----------------------------------------------------´

• length - always 6.
• status - 1 if OK, 0 on error.
• pwm_step - fade effect intensity. Range from 0 to 100.
• RGB fields - range from 0 to 100 each.

Roadmap

• Change colors with PWM
• Connect to wifi
• Accept TCP connection
• Respond TCP connection
• Optional POST parameters
  • duration of fade effect to new RGB color
• GET pwm_step and rgb
• return pwm_step and rgb in POST
• respond to discovery broadcast message
• Qt App
  • discover lamp ip
  • change color
