AutoStand: Smart Standing Desk Automation

AutoStand is a Python-based automation tool for standing desks, specifically designed for desks with preset buttons. It uses a Raspberry Pi and a 4-channel relay board to simulate physical button presses, allowing you to schedule desk height changes automatically.

Hardware Requirements

• Raspberry Pi (e.g., Pi 3 or Pi 4)
• 4-Channel Relay Board (Active Low recommended)
• Breadboard and Jumper Wires
• Standing Desk Control Board (with access to button contacts)

Connection Diagrams

1. Raspberry Pi to Relay Board (via Breadboard)

Connect the Raspberry Pi GPIO pins to the relay board inputs using a breadboard for easy wiring and power distribution.

Raspberry Pi Pin	Connection Type	Relay Board Pin
5V (Pin 2/4)	Power	VCC
GND (Pin 6/etc)	Ground	GND
GPIO 23 (Pin 16)	Signal	IN1 (Preset 1)
GPIO 27 (Pin 13)	Signal	IN2 (Preset 2)
GPIO 22 (Pin 15)	Signal	IN3 (Preset 3)
GPIO 17 (Pin 11)	Signal	IN4 (Preset 4)

Note

GPIO numbers refer to BCM numbering, which matches the configuration in config/settings.json.

2. Relay Board to Standing Desk Board

Connect the output terminals of each relay across the button contacts on your desk's control board.

• Each relay acts as a momentary switch.
• Connect the COM (Common) and NO (Normally Open) terminals of the relay to the two sides of the corresponding preset button on the desk board.

Software Setup

1. Clone the repository:

   git clone <repository-url>
   cd AutoStand

2. Configure Settings: Edit config/settings.json to match your pin connections and desired automation durations.

   {
       "pins": {
           "preset_1": 23,
           "preset_2": 27,
           "preset_3": 22,
           "preset_4": 17
       },
       "automation": {
           "sit_duration_minutes": 15,
           "stand_duration_minutes": 15,
           "sit_preset": 1,
           "stand_preset": 4
       }
   }

3. Install Dependencies:

   pip install RPi.GPIO

4. Run the Application:

   python main.py

Safety Warning

Caution

Always disconnect your desk from power before soldering or making connections to the desk's control board. Ensure no wires are loose, as a short circuit could damage your desk board or Raspberry Pi.
