  • Weak Wi-Fi connection or frequency not supported.

Guide to Troubleshoot ‘Meross Light Bulb Unreachable’ Issue

Check the Power Source

To check the power source of a Meross light bulb, you can first ensure that the socket the bulb is plugged into is working properly.

If the socket is working, you can try turning off the bulb via the control switch and then turning it on and off five times, leaving it in the ON position.

This will reset the bulb to its factory settings, which will erase all previous settings in the app, so you will need to set it up properly as you did when you first installed it.

Restart Your Router

To restart your router and fix the issue of a Meross light bulb being unreachable, you can follow these steps.

  • First, unplug your router and modem from the power source
  • Wait for at least 30 seconds before plugging them back in.
  • After the router and modem have restarted, try connecting to the Meross light bulb again.

Check Your Wi-Fi Frequency

If you are experiencing issues with a Meross light bulb being unreachable, it could be due to weak Wi-Fi signal or an unsupported Wi-Fi frequency.

Meross light bulbs can only connect to a 2.4GHz Wi-Fi frequency, so if you have a dual-band router that changes bandwidth automatically, your bulb may disconnect whenever the router switches to the 5GHz Wi-Fi band.

To check your Wi-Fi frequency, navigate to your router’s admin page and check the 2.4 and 5.0 split SSID settings.

If your router is set to run on the 5GHz frequency, you can switch it to the 2.4GHz frequency only.

After optimizing your router, check the app to see if the bulb is now online.

Update the App

Are you using an Android device? Make sure to check the Google Play Store for any updates on the Meross app. Updating could help avoid potential issues that arise from running an outdated version. For iOS users, take a peek at the Apple App Store and update the Meross app if there are any new updates available. It’s a simple way to prevent problems down the line.

Are you using a third-party app like Smart Life? Make sure you have the most recent version for optimal performance.

Meross devices work best with the Meross app, so if you’re using something else, you might want to switch over. This could lead to improved performance and a better user experience.

Third-party apps can be convenient, but they may not give you the same user experience as the Meross app. Consider making the switch for the most reliable performance.

Perform a Factory Reset

To perform a factory reset on a Meross smart bulb, you can turn off the light switch that controls the bulb and then turn the light switch on and off five times, leaving it in the ON position.

After restoring the factory settings, the smart bulb will clear all custom settings, so you must set it up again.

However, it is important to note that different sources suggest different reset methods for Meross smart bulbs. For example, some sources suggest turning the light switch on and off three times instead of five.

If the first method does not work, you can try other methods such as turning the light on and off ten times.
