# SinricPro TV Example
This example demonstrates how to control a TV device using SinricPro with voice commands via Alexa or Google Home.
## Features
This example showcases all TV capabilities:
- **Power Control** - Turn TV on/off
- **Volume Control** - Set or adjust volume (0-100)
- **Mute Control** - Mute/unmute audio
- **Media Control** - Play, pause, stop, next, previous
- **Input Selection** - Switch between HDMI1, HDMI2, AV, etc.
- **Channel Control** - Change channels by number or skip channels
- **Settings** - Configure TV settings
## Hardware Required
- ESP32, ESP32-S2, ESP32-S3, ESP32-C3, or ESP32-C6 development board
- USB cable for power supply and programming
- (Optional) LED connected to GPIO2 to visualize TV state
- Built-in BOOT button (GPIO0) for manual control
## How to Use
### 1. Setup SinricPro Account
1. Create a free account at [sinric.pro](https://sinric.pro)
2. Go to "Devices" and click "Add Device"
3. Select device type: **TV**
4. Give it a name (e.g., "Living Room TV")
5. Note down the **Device ID**, **App Key**, and **App Secret**
### 2. Configure the Example
Edit `main/tv_example.c` and update the following:
```c
/* WiFi Configuration */
#define WIFI_SSID "YOUR_WIFI_SSID"
#define WIFI_PASS "YOUR_WIFI_PASSWORD"
/* SinricPro Configuration */
#define DEVICE_ID "YOUR_DEVICE_ID" /* From SinricPro portal */
#define APP_KEY "YOUR_APP_KEY" /* From SinricPro portal */
#define APP_SECRET "YOUR_APP_SECRET" /* From SinricPro portal */
```
### 3. Build and Flash
```bash
cd examples/tv
idf.py set-target esp32 # or esp32s2, esp32s3, esp32c3, esp32c6
idf.py build
idf.py flash monitor
```
### 4. Voice Commands
Once the device is online, you can control it with voice commands:
**Power Control:**
- "Alexa, turn on the TV"
- "Alexa, turn off the TV"
**Volume Control:**
- "Alexa, set TV volume to 50"
- "Alexa, increase TV volume"
- "Alexa, decrease TV volume by 10"
**Mute Control:**
- "Alexa, mute the TV"
- "Alexa, unmute the TV"
**Input Selection:**
- "Alexa, change TV to HDMI 1"
- "Alexa, switch TV input to HDMI 2"
**Channel Control:**
- "Alexa, change TV to channel 5"
- "Alexa, next channel"
- "Alexa, previous channel"
- "Alexa, channel up"
**Media Control:**
- "Alexa, play" (when watching streaming apps)
- "Alexa, pause"
- "Alexa, stop"
## Physical Button Control
Press the built-in BOOT button (GPIO0) to toggle the TV power state. The built-in LED (GPIO2) will indicate the current state.
## Customization
### Modify GPIO Pins
Change the LED and button GPIO pins in `main/tv_example.c`:
```c
#define LED_GPIO GPIO_NUM_2 /* Your LED GPIO */
#define BUTTON_GPIO GPIO_NUM_0 /* Your button GPIO */
```
### Add Custom Actions
Implement custom logic in the callback functions:
```c
static bool on_media_control(const char *device_id, const char *control, void *user_data)
{
if (strcmp(control, "Play") == 0) {
/* Your play logic */
} else if (strcmp(control, "Pause") == 0) {
/* Your pause logic */
}
return true;
}
```
### Send TV Events
Report TV state changes to SinricPro:
```c
/* Power state changed */
sinricpro_tv_send_power_state_event(my_tv, true, SINRICPRO_CAUSE_PHYSICAL_INTERACTION);
/* Volume changed */
sinricpro_tv_send_volume_event(my_tv, 75, SINRICPRO_CAUSE_PHYSICAL_INTERACTION);
/* Channel changed */
sinricpro_tv_channel_t channel = {5, "HBO"};
sinricpro_tv_send_channel_event(my_tv, &channel, SINRICPRO_CAUSE_PHYSICAL_INTERACTION);
```
## Troubleshooting
**Device doesn't connect:**
- Check WiFi credentials
- Verify internet connection
- Ensure SinricPro credentials are correct
**Voice commands don't work:**
- Make sure device shows as "Online" in SinricPro portal
- Check that Alexa/Google Home skill is linked
- Try device discovery: "Alexa, discover devices"
**Rate limiting errors:**
- Events are limited to 1 per second for state changes
- Add delays between rapid state changes
