How to Fix a Merkury Smart Device That Is Offline

It's a common smart home frustration: you open the Geeni app to turn on your Merkury smart bulb or plug, only to find it's greyed out with the word 'Offline'. An offline device is unresponsive and can't be controlled, but the good news is that the fix is usually quick and simple.

This guide will walk you through the most common causes for a Merkury device going offline and the steps you need to take to reconnect it.

### Common Signs of an Offline Device

  • 'Offline' Status: The device is greyed out in the Geeni app and is labelled as 'Offline'.
  • Unresponsive: Tapping the on/off button in the app has no effect.
  • Blinking Light: A smart bulb may be blinking rapidly, which indicates it has lost its connection and is in pairing mode.
  • 'Device is offline' Error: You see a specific error message when you try to control the device.
  • Works Manually: You can still turn the light on and off with the physical light switch, but not with the app.

Step-by-Step Guide to Getting Your Merkury Device Back Online

Let's start with the most basic checks and move on to reconnection steps.

1. Check the Obvious: Power and Switches

Before diving into network issues, check the physical power source.

  • For Smart Bulbs: Is the light switch or lamp switch turned on? A smart bulb needs a constant supply of power to stay connected to the network. If someone flips the switch off, the bulb goes offline.
  • For Smart Plugs: Is the plug firmly in the wall socket, and is the socket switched on? Have you accidentally turned off the power button on the plug itself?

2. Check Your Internet and Router

If the power is on, the next suspect is your home network.

  • Is your Wi-Fi working? Check if other devices in your home, like your phone or laptop, can connect to the internet.
  • Reboot Your Router: Unplug your Wi-Fi router from the power, wait for 30 seconds, and plug it back in. It will take a few minutes to restart. This simple step resolves a surprising number of connectivity issues. While the router is restarting, it's a good idea to power cycle your Merkury device too (by flicking the switch off and on).

3. Have Your Wi-Fi Details Changed?

This is the most common reason for a device to permanently go offline.

  • New Password or Router: If you have recently changed your Wi-Fi password, or installed a new internet router, your Merkury device is still trying to connect using the old, incorrect details.
  • The Solution: Because the device cannot connect to receive new instructions, you must perform a reset and set it up again as if it were a new device.

4. How to Reset and Reconnect Your Merkury Device

If your Wi-Fi password has changed or a simple reboot didn't work, you'll need to reconnect your device.

  1. Put the Device in Pairing Mode:
    • For a Smart Bulb: With the bulb in a socket that is switched on, turn the power switch off and on 3 times (Off-On, Off-On, Off-On). The bulb will begin to blink rapidly, indicating it is in pairing mode.
    • For a Smart Plug: Press and hold the power button on the side of the plug for about 5 seconds until the indicator light starts blinking rapidly.
  2. Delete the Offline Device: In the Geeni app, it's best to remove the old offline version of the device first. Tap on the device, then the settings icon, and choose 'Remove Device'.
  3. Add a New Device:
    • In the Geeni app, tap the '+' icon to add a new device.
    • Select the type of device you are adding (e.g., 'Smart Lighting').
    • Ensure your phone is connected to your 2.4GHz Wi-Fi network.
    • Follow the on-screen prompts, confirm the device is blinking rapidly, and enter your Wi-Fi password.
    • The app will then reconnect to the device and add it back to your account.

By following these steps, you can quickly diagnose why your Merkury device went offline and get it reconnected to your smart home system.

Frequently Asked Questions

This usually happens for one of three reasons: the device has lost power (check the switch/plug), your Wi-Fi router is off or has lost internet, or you have recently changed your Wi-Fi network's name or password, which means the bulb can no longer connect.

Yes. A rapidly blinking light on a Merkury bulb means it has lost its Wi-Fi connection and has entered pairing mode. This happens if it can't find the network it was previously connected to. You will need to go through the 'Add Device' process in the Geeni app to reconnect it to your network.

No, Merkury smart devices require a 2.4GHz Wi-Fi network to operate. Most modern routers are dual-band (offering both 2.4GHz and 5GHz). Ensure your phone is connected to the 2.4GHz band during the setup process. If your router uses a single name for both bands, you may need to temporarily disable the 5GHz band in your router's settings during setup.
