What should I do if my third-party Matter device shows offline in Tapo app?

Introduction

The Tapo HomeBase communicates with third-party devices using the universal Matter protocol. When the HomeBase cannot "heartbeat" with the device for a set period, the device will appear as Offline in the Tapo app. This guide provides a systematic approach to restoring that connection.

Requirements

• Tapo Homebase (e.g. Tapo H500) as the Matter controller in Tapo app
• Compatible Matter Devices: Currently supports smart bulbs and plugs

Troubleshooting

Tip 1: Check HomeBase connection

Try to change some settings on HomeBase to check if you can control HomeBase successfully. If the HomeBase connection is unstable, connect the HomeBase to the router via an Ethernet Cable.

Tip 2: Test the third-party Matter devices’ connection

Open the original manufacturer’s app or other Matter platform for the offline device. If the device is also offline there, the issue is likely hardware-related or specific to the device's local Wi-Fi/Thread connection. Contact the manufacturer for further support.

Tip 3: Firmware Update

Update both the Tapo HomeBase and the Matter device’s firmware to the latest versions. Usually, the Matter device's firmware needs to be configured and updated via the manufacturer's app.

Tip 4: Restart Devices

Restart your router, Tapo HomeBase, and the Matter device to refresh connections.

QA

Q1: Does the distance between the HomeBase and the Matter device matter?

A1: Tapo Homebase acts as a Matter controller, which controls the Matter devices via the local network. So what matters is that the Matter device need to keep good connection with the router/Matter bridge devices.
