Product Overview
The DiO micro-module is a small, battery-powered transmitter that converts the action of a traditional wall switch into a wireless radio signal. This signal can then control any compatible DiO 1.0 receiver within a 50-meter range (in open field).

- Compact Design: Fits easily behind most standard wall switches.
- Wireless Control: Transmits radio signals (433.92 MHz) to DiO 1.0 receivers.
- Battery Powered: Uses a 3V CR2032 battery (not included).
- Dual Input: Features S1 and S2 terminals for single or double switch configurations.
Installation
The micro-module is designed for easy installation behind an existing wall switch. Ensure the main power supply to the circuit is turned OFF before proceeding with installation.
- Prepare the Switch Box: Carefully remove your existing wall switch from its mounting box. Ensure there is sufficient space behind the switch for the micro-module (Dimensions: 14.4 x 10.9 x 2.5 cm).
- Connect the Micro-module:
- Connect the wires from your wall switch to the S1 and/or S2 terminals on the DiO micro-module.
- For a single switch, use S1. For a double switch (e.g., two-way switch), use both S1 and S2.
- Important: This micro-module is a transmitter and does not require connection to the 220V mains power. It is battery-operated. Do NOT connect it to the main electrical circuit.
- Insert Battery: Open the battery compartment on the micro-module and insert a 3V CR2032 battery, observing correct polarity.
- Position the Module: Carefully place the micro-module into the wall switch box, ensuring wires are not pinched.
- Reinstall Switch: Mount your wall switch back into its position.
- Restore Power: Turn the main power supply back ON.

Operating Instructions
Once installed, the DiO micro-module acts as a wireless transmitter for your wall switch. It allows you to control any compatible DiO 1.0 receiver.
Pairing with DiO Receivers
To control a DiO receiver (e.g., a lighting module, smart plug, or shutter module), you must first pair the micro-module with the receiver. The pairing process typically involves:
- Activate Learning Mode on Receiver: Refer to your DiO receiver's manual to put it into learning mode. This usually involves pressing a button on the receiver for a few seconds.
- Send Pairing Signal: Within 10 seconds of activating learning mode on the receiver, press the wall switch connected to your DiO micro-module. The receiver should confirm successful pairing (e.g., by flashing a light or making a sound).
- Test Functionality: Once paired, operate the wall switch to ensure it controls the receiver as expected (e.g., turn lights ON/OFF).
The micro-module supports ON/OFF functions and can be used to centralize control of multiple devices or activate specific scenarios within your DiO smart home system.
Maintenance
- Cleaning: Clean the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: The micro-module is powered by a 3V CR2032 battery. When the battery is low, the transmission range or reliability may decrease. Replace the battery as needed. Ensure proper disposal of old batteries.
- No User-Serviceable Parts: Do not attempt to open or repair the micro-module yourself. This will void the warranty.
Troubleshooting
- Device Not Responding:
- Check the battery in the micro-module. Replace if necessary.
- Ensure the micro-module is correctly paired with the DiO receiver. Repeat the pairing process if unsure.
- Verify that the DiO receiver is powered on and functioning correctly.
- Check the distance between the micro-module and the receiver. Obstacles like thick walls or metal structures can reduce the wireless range.
- Intermittent Operation:
- This could indicate a low battery. Replace the CR2032 battery.
- Interference from other wireless devices operating on the same frequency (433.92 MHz) might occur. Try to minimize such interference.
- Switch Not Activating Module:
- Ensure the wall switch is correctly wired to the S1/S2 terminals of the micro-module.
