5. Installation
WARNING: Please install and maintain the device by a professional electrician. To avoid electric shock hazard, do not operate any connection or contact the terminal connector while the device is powered on!
5.1. Sluk
Before any installation or wiring, ensure the power is completely off at the circuit breaker. This is crucial for safety.

Image: Illustration of turning off power at the circuit breaker.
5.2. Ledningsinstruktioner
To ensure the safety of your electrical installation, it is essential that either a Miniature Circuit Breaker (MCB) or a Residual Current Operated Circuit Breaker (RCBO) with an electrical rating of 10A has been installed before the MINIR4M.
The MINIR4M supports various external switch types, including momentary, door exit, SPDT, and latching switches. Ensure all wires are connected correctly.
Vigtige bemærkninger:
- Uanset om S1 og S2 er tilsluttet eller efterladt inaktiv til den eksterne kontakt, kan denne enhed styres af automatisering eller appen.
- Det er forbudt at forbinde S1 og S2 terminaler til nul- eller jordledningen for at undgå at beskadige udstyret og forårsage fare.
- Sørg for, at alle ledninger er tilsluttet korrekt.
Ledningsdiagrammer:

Brugertip: The wiring diagrams provided typically show a single load (e.g., one light bulb). If you intend to control multiple light bulbs with a single MINIR4M, ensure the total wattage of all connected bulbs does not exceed the device's maximum power rating (2400W@240V or 10A Max). Connect multiple loads in parallel to the 'L Out' and 'N' terminals, ensuring proper insulation and safety.
5.3. Fysisk installation
The MINIR4M's tiny size allows it to fit into various mounting boxes, including the smallest European standard ones. Ensure there is enough space for the device and wiring within the box.

6. Opsætning og parring
After powering on the device, it will enter the Pairing Mode by default during the first use. The Network indicator (blue LED) will flash in a cycle of two short and one long blinks.
The device will exit Pairing Mode if not paired within 10 minutes. To re-enter Pairing Mode, long press the button for 5 seconds until the Network indicator flashes in a cycle of two short and one long blinks, then release.
6.1. Method 1: Matter Pairing
For Matter pairing, you can use a Matter-compatible app such as Amazon Alexa, Google Home, or Apple Home. Download the respective app if you haven't already.
- Open your preferred Matter-compatible App (e.g., Alexa App, Google Home App, or Apple Home App).
- Scan the Matter QR code found on the Quick Guide or directly on the device itself.
- Follow the on-screen instructions within the app to add the device.

6.2. Method 2: eWeLink App Pairing
If you prefer to use the eWeLink App, follow these steps:
- Download eWeLink-appen: Søg efter "eWeLink" in the Google Play Store (Android) or Apple App Store (iOS) and install it.
- Tænd for enheden: Ensure the MINIR4M is powered on and in pairing mode (blue LED flashing two short, one long).
- Tilføj enhed i appen:
- Åbn eWeLink-appen.
- Tryk på ikonet "+" eller på muligheden "Tilføj enhed".
- Select "Scan QR code" or follow the prompts to search for nearby devices.
- If prompted, long press the button on the MINIR4M for 5 seconds to ensure it's in pairing mode.
- Check the Wi-Fi LED indicator flashing status (two short and one long flashes).
- Vælg dit Wi-Fi-netværk, og indtast adgangskoden.
- Once connected, the device will be added to your eWeLink account.
7. Betjeningsvejledning
7.1. Manuel kontrol
Press the physical button on the MINIR4M once to change the on/off state of the relay contacts, controlling the connected appliance.
7.2. Appkontrol
Once paired, you can control the MINIR4M via the eWeLink App or your chosen Matter-compatible app (Apple Home, Google Home, Alexa). This allows you to turn devices on/off remotely, set schedules, and create smart scenes.
7.3. Stemmekontrol
Integrate the MINIR4M with voice assistants like Amazon Alexa, Google Assistant, or Apple HomeKit to control your connected devices using voice commands.
7.4. Detach Relay Mode
In "Detach Relay" mode, the states of external switches (S1/S2) and the internal relay are separated. This means operating the external switch button will not affect the relay's state. For example, if you enable this mode, your smart light will not go offline when you turn off the physical switch, and you can still control it via the app.

Image: Illustration of Detach Relay mode where a smart light remains online despite the physical switch being off.

Image: Illustration of normal operation without Detach Relay mode, where the physical switch directly controls the light.
7.5. Timer- og tidsplanfunktioner
Use the eWeLink App or your Matter-compatible app to set various timers (single, countdown, loop) and schedules to automate your appliances. For example, you can set lights to turn on automatically at 8:00 PM.
7.6. Smarte scener
Create smart scenes by integrating the MINIR4M with other sensors (e.g., motion, door, window sensors) to automate actions based on specific triggers.

7.7. Delay Power-on State
This feature provides additional protection by allowing you to set a delay for appliances to power on after a power outage. This prevents all appliances from turning on simultaneously, which could cause high currents and potential damage.

8. Vedligeholdelse
- Hold enheden ren og tør.
- Undgå at udsætte enheden for ekstreme temperaturer eller fugt.
- Forsøg ikke selv at skille enheden ad eller reparere den. Kontakt kundesupport, hvis der opstår problemer.
- Regularly check for firmware updates through the eWeLink App or your Matter-compatible app to ensure optimal performance and security.
9. Fejlfinding
9.1. Device Not Responding / Offline
- Tjek strøm: Ensure the MINIR4M is receiving power.
- Wi-Fi-forbindelse: Verify your Wi-Fi network is active and the device is within range. If using eWeLink, check the app for device status. For Matter, local communication should still work even without internet.
- Reparation: If the device remains unresponsive, try re-entering pairing mode (long press button for 5s) and re-pairing it with your app.
- Problemer med routeren: Genstart din Wi-Fi-router.
9.2. External Switch Not Working
- Ledningskontrol: Double-check the wiring connections for S1 and S2 terminals as per the installation diagrams. Ensure no loose connections.
- Switch Type: Confirm the external switch type is compatible (momentary, door exit, SPDT, latching).
- Afbryd relætilstand: If "Detach Relay" mode is enabled, the physical switch will not directly control the load. Control via app or voice assistant.
9.3. Pairing Fails
- Parringstilstand: Ensure the device is in pairing mode (blue LED flashing two short, one long).
- Wi-Fi-legitimationsoplysninger: Verify the Wi-Fi network name and password entered are correct.
- 2.4 GHz Wi-Fi: The device only supports 2.4GHz Wi-Fi networks. Ensure your router is broadcasting on this frequency.
- Nærhed: Keep your phone close to the MINIR4M during the pairing process.
- Routerindstillinger: Some routers may have settings that interfere with smart device pairing. Consult your router's manual or ISP.
9.4. Overophedning
- Indlæsningskontrol: Ensure the connected load does not exceed the maximum rating (10A Max / 2400W@240V).
- Ventilation: Ensure the installation location allows for adequate ventilation.
10. Brugertips
- Materieintegration: When integrating with Matter, remember that you can generate a new setup code from one ecosystem app (e.g., Alexa) to sync the device to another (e.g., Apple Home). This allows for cross-platform control.
- Lokal kontrol: Tag advantage of the local communication feature. Even if your internet goes down, your MINIR4M devices should still respond to commands within your local network, ensuring basic functionality.
- Automatiser med scener: Explore creating smart scenes with other sensors (motion, door/window) to automate daily routines and enhance convenience.
