Native C SDK for connecting Raspberry Pi Pico W devices to SinricPro smart home platform.

• Native pico-sdk implementation (C11)
• WebSocket client with TLS support
• Compatible with Alexa, Google Home, and SinricPro app
• Low memory footprint
• Polling-based architecture (no RTOS required)

• Switch - Simple on/off control for relays, smart plugs, etc.
• DimSwitch - Dimmable switch with power level control (0-100%)
• Light - RGB+CCT smart light with full color and color temperature control
  • On/off control
  • Brightness adjustment (0-100%)
  • RGB color (0-255 per channel)
  • Color temperature (2200K-7000K warm to cool white)
• Fan - Speed control for fans and ventilation systems
  • On/off control
  • Speed adjustment (0-100%)
• Lock - Smart lock control for doors and access control
  • Lock/unlock commands
  • Status reporting (LOCKED/UNLOCKED/JAMMED)
• GarageDoor - Garage door opener control
  • Open/close commands
  • Position status monitoring
• Blinds - Motorized blinds/shades position control
  • Position control (0-100%, where 0=fully open, 100=fully closed)
  • Relative adjustments ("open blinds 30 percent")

• Motion Sensor - PIR motion detection for automation and security
• Temperature Sensor - Temperature and humidity monitoring
• Contact Sensor - Door/window open/close detection
• PowerSensor - Real-time power consumption monitoring
  • Voltage, current, power measurements
  • Watt-hours energy tracking
  • Power factor calculation

  • PM1.0, PM2.5, PM10 particulate matter detection
  • Air quality index (AQI) reporting

• Doorbell - Doorbell press notifications
  • Push notifications on doorbell press
  • Automation triggers

All devices support:

• Voice control via Alexa and Google Home
• SinricPro mobile app integration
• Alexa routines and automations
• Real-time status updates

The following complex devices require additional capabilities and are planned for future releases:

• TV - Television control (requires 8 capabilities)
• Speaker - Smart speaker control (requires 7 capabilities)
• WindowAC - Window air conditioner control (requires 5 capabilities)
• Camera - IP camera streaming (requires specialized camera capabilities)

# Clone the SDK
git clone https://github.com/sinricpro/pico-sdk.git
cd pico-sdk

# Add cJSON dependency
git submodule add https://github.com/DaveGamble/cJSON.git lib/cJSON

export PICO_SDK_PATH=/path/to/pico-sdk

mkdir build && cd build
cmake ..
make

Hold BOOTSEL button, connect Pico W via USB, then:

cp examples/switch/sinricpro_switch_example.uf2 /media/$USER/RPI-RP2/

#include "sinricpro/sinricpro.h"
#include "sinricpro/sinricpro_switch.h"

sinricpro_switch_t my_switch;

bool on_power_state(sinricpro_device_t *device, bool *state) {
    printf("Power: %s\n", *state ? "ON" : "OFF");
    gpio_put(LED_PIN, *state);
    return true;
}

int main() {
    sinricpro_config_t config = {
        .app_key = "your-app-key",
        .app_secret = "your-app-secret"
    };

    sinricpro_init(&config);
    sinricpro_switch_init(&my_switch, "your-device-id");
    sinricpro_switch_on_power_state(&my_switch, on_power_state);
    sinricpro_add_device((sinricpro_device_t *)&my_switch);
    sinricpro_begin();

    while (1) {
        sinricpro_handle();
        sleep_ms(10);
    }
}
