You can also use a specific version tag for better control over updates:
```yaml
ref: v2024.12.2 # Using specific version for controlled updates
```

5. Click "Save" and then "Install"
### Device Flashing
Initial flashing must be done via serial connection.
We recommend using [ESPHome Web](https://web.esphome.io) for the simplest experience.
<!-- markdownlint-disable MD028 -->
> [!IMPORTANT]
> **SAFETY WARNINGS**
> - ALWAYS disconnect the device from mains power before opening
> - NEVER work on the device while connected to mains power
> - Ensure the device is completely powered off before making any connections
> - Keep your workspace clean, dry, and static-free
> - Use proper insulated tools when working with electronics
> - If unsure about any step, seek help from an experienced person
> [!CAUTION]
>⚡ **CRITICAL: VOLTAGE WARNING**
> Using a UART adapter with voltage higher than 3.3V WILL DAMAGE YOUR DEVICE.
> Double-check your adapter's voltage before connecting - many common FTDI adapters
> default to 5V which will permanently damage the ESP32 chip.
<!-- markdownlint-enable MD028 -->
#### Required Hardware
- USB-to-UART adapter:
- 3.3V logic level ONLY (DO NOT use 5V adapters)
- Must be capable of supplying at least 500mA
- Common adapters: CP2102, CH340, FTDI (ensure 3.3V setting)
- Small Phillips screwdriver
- 5 wires for connections (including one for BOOT to GND)
#### Flashing Process
1. Open your TX Ultimate device carefully
2. Locate the programming header pins
3. Connect your USB-to-UART adapter:
| Adapter | Device |
|---------|--------|
| GND | GND |
| 3.3V | 3.3V |
| TX | RX |
| RX | TX |
4. Put device in flash mode:
- Temporarily connect the BOOT pin to GND using a jumper wire
- While holding BOOT to GND, power up the device
- After device powers up (wait a couple of seconds), remove the BOOT to GND connection
5. Visit [ESPHome Web](https://web.esphome.io)
6. Connect to your device and flash the firmware
7. After successful flash, device will restart and be ready for OTA updates
#### Detailed Visual Guides
<!-- markdownlint-disable MD013 -->
For step-by-step visual instructions, you can reference these existing guides:
- 🇬🇧 [WirelessThings Guide](https://wirelessthings.io/index.php/2023/12/19/how-to-flash-sonoff-tx-ultimate-with-esphome/) - English guide with detailed photos
- 🇪🇸 [Un loco y su tecnología](https://youtu.be/58v8oqSQgXQ?t=143) - Spanish video tutorial
- 🇩🇪 [SmartHome yourself](https://youtu.be/naDLhX89enQ?t=465) - German video tutorial
<!-- markdownlint-enable MD013 -->
Note: While these guides may use different firmware, the physical flashing process remains the same.
#### Subsequent Updates
After initial flashing, all future updates can be done wirelessly (OTA)
through the ESPHome dashboard in your ESPHome add-on.
### Home Assistant Integration
After successful flashing:
1. Ensure your device and Home Assistant are on the same network
2. Device should be automatically discovered within 1–2 minutes
3. Accept the discovery notification in Home Assistant to add device
Note: If discovery takes longer than 5 minutes, proceed to troubleshooting steps
4. Device will appear in your Home Assistant Devices dashboard
#### Troubleshooting Integration
If the device isn't discovered automatically:
1. Verify your device is powered and connected to your network:
- Look for the device in your router's client list
- Consider using [manual IP](https://esphome.io/components/wifi.html#manual-ips) in your device
2. If you missed the discovery notification:
- Go to Settings → Devices & Services
- Click "Add Integration"
- Search for "ESPHome" and enter your device's IP address
3. Still having issues?
- Check your network allows mDNS/discovery traffic
- Verify there are no VLANs or network isolation preventing communication
- Try rebooting both the device and Home Assistant
### Initial Configuration
1. In Home Assistant, navigate to:
- Settings → Devices & Services → ESPHome
- Click on your device to access its configuration page
2. Set basic device parameters:
- Model format (EU/US)
- Number of gangs (1-4)
- Relay modes (switch/light)
- Button actions
3. Optional: Configure advanced features
- LED behaviors
- Touch sensitivity
- Haptic feedback
- Audio feedback
4. Test your configuration:
- Verify each relay responds to controls
- Test configured button actions
- Confirm LED behavior matches settings
- Check haptic/audio feedback if enabled
> [!NOTE]
> Some changes may require a device restart
