3.3. Device Connection (Wi-Fi)
- Open the BroadLink App and sign in or create a new account.
- Tap "+" on the top right corner and choose "Add device". The app will start scanning for devices.
- Choose your home Wi-Fi network (2.4 GHz only) and enter the password. The RM4 Pro does not support 5 GHz Wi-Fi networks. If you have a dual-band router, temporarily disable the 5 GHz band during setup if you encounter connection issues.
- Tap "Connect to Wi-Fi". The LED indicator on the RM4 Pro will flash slower and then turn off once successfully connected.
- Choose a room and name your device for easy identification.

3.4. Adding IR/RF Appliances
After connecting the RM4 Pro to your Wi-Fi network, you can start adding your appliances.
- In the app, tap "Add appliances".
- Choose the type of appliance (e.g., TV, A/C, STB) and its brand. The app will attempt to find a matching code from its cloud library.
- If your brand or model is not found, you can use the "Learn button" or "Continue match" options to manually teach the RM4 Pro commands from your original remote.
- For IR code learning, aim your appliance remote control at the RM4 Pro. Wait for the device LED indicator to light up, then briefly press the remote button you want to learn.
- For RF appliances, follow the specific instructions in the app for RF code learning, which may involve pressing buttons multiple times or for a longer duration.

4. Operating Instructions
Once your devices are set up, you can control them using the BroadLink App or voice commands.
4.1. App Control
The BroadLink App provides a virtual remote interface for each added appliance. You can power devices on/off, change channels, adjust volume, set temperatures, and perform other functions just as you would with their original remote controls. The app also allows for creating custom scenes and routines.
4.2. Voice Control (Alexa & Google Home)
The RM4 Pro is compatible with Amazon Alexa and Google Home for voice control. To enable this feature:
- Open the Alexa or Google Home app.
- Enable the "BroadLink" skill/service.
- Link your BroadLink account with your Alexa/Google Home account.
- Discover devices. Your configured appliances from the BroadLink App should now appear in your voice assistant app.
You can then use voice commands such as: "Alexa, turn on TV" or "Hey Google, set A/C to 24 degrees."

4.3. Scheduling and Routines
Create schedules and routines within the BroadLink App or your voice assistant app to automate your devices. For example, you can set your air conditioner to turn on before you arrive home or schedule your curtains to open at sunrise.
4.4. Temperature and Humidity Monitoring
If you have purchased the external Temperature and Humidity Sensor USB Cable (sold separately), connect it to the RM4 Pro. The BroadLink App will then display real-time room temperature and humidity, allowing for more intelligent automation based on environmental conditions.
5. Maintenance
To ensure the longevity and optimal performance of your BroadLink RM4 Pro, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the device. Avoid using liquid cleaners or aerosols, as they may damage the device.
- Placement: Place the RM4 Pro in a central location within the room where it can have a clear line of sight to IR-controlled devices. Avoid placing it behind obstacles or in direct sunlight.
- Firmware Updates: Regularly check for and install firmware updates through the BroadLink App. Updates often include performance improvements, bug fixes, and new features.
- Power Supply: Always use a stable 5V 1A/2A USB power adapter. Unstable power can affect device performance and lifespan.
6. Troubleshooting
If you encounter issues with your BroadLink RM4 Pro, refer to the following common troubleshooting steps:
- Device Not Connecting to Wi-Fi:
- Ensure your Wi-Fi network is 2.4 GHz. The RM4 Pro does not support 5 GHz networks.
- Verify your Wi-Fi password is correct.
- Try temporarily disabling the 5 GHz band on your router during the setup process.
- Move the RM4 Pro closer to your Wi-Fi router.
- Perform a factory reset on the RM4 Pro (refer to Figure 2.6 for reset button location) and attempt setup again.
- IR/RF Commands Not Working:
- Ensure the RM4 Pro has a clear line of sight to the IR-controlled appliance.
- During the learning process, ensure the original remote is aimed directly at the RM4 Pro and pressed firmly.
- Verify the frequency of your RF device (RM4 Pro supports 433MHz). Some older or specialized RF devices may use different frequencies (e.g., 308MHz, 868MHz) or rolling codes, which are not supported.
- Re-learn the problematic commands if they are not consistently working.
- Voice Control Issues:
- Confirm that the BroadLink skill/service is enabled and linked correctly in your Alexa/Google Home app.
- Ensure your devices are discovered by the voice assistant.
- Check your internet connection.
