Understanding "Offline" Status

A device shows as Offline when the app cannot establish a real-time connection to it via the cloud. This happens when the device has lost its path to the internet — not necessarily because the device itself is broken. There are three layers where connectivity can break:

1. Device to Wi-Fi router — the device cannot connect to your home network.
2. Router to internet — your home network has no internet access.
3. Cloud service — the TS Smart Home cloud cannot be reached from anywhere.

Quick Fixes to Try First

Before deeper investigation, try these in order:

• Check your internet: Open a browser on your phone and confirm you have internet access.
• Power cycle the device: Unplug it for 10 seconds and plug it back in.
• Refresh the app: Pull down on the dashboard to force a refresh, or close and reopen the app.
• Restart your router: Unplug it for 30 seconds. Many temporary disconnections resolve this way.

If the device comes back online after any of these, you are done.

Cause 1: Wi-Fi Credentials Changed

If your Wi-Fi password or router SSID changed, the device needs to be re-paired because it still knows the old credentials.

1. Reset the device to factory settings (hold button for 10 seconds).
2. Re-enter pairing mode (hold button for 5 seconds).
3. Follow the pairing process in the app with your new Wi-Fi credentials.

Cause 2: Weak Wi-Fi Signal

Devices too far from the router may disconnect intermittently, especially when the router is under load. Check your router's admin panel for the device's RSSI signal strength — anything weaker than -70 dBm will cause intermittent disconnections. Move the device closer to the router, or add a Wi-Fi range extender.

Cause 3: Router Blocking the Device

Several router settings can silently block smart device connectivity:

• MAC address filtering: Add your device's MAC address to the router's allowed list.
• Client isolation: Disable this setting — it blocks device-to-cloud communication.
• DHCP lease exhaustion: Reboot the router to clear old DHCP leases.
• Firewall rules: Ensure outbound MQTT connections on port 8883 or 1883 are allowed.

Cause 4: Internet Outage

If multiple devices go offline simultaneously, your internet connection is likely the cause. Wait for internet service to be restored — TS Smart Home devices reconnect automatically when the connection returns. No reconfiguration is needed.

When multiple devices at different locations report offline at the same time, it may indicate a temporary cloud service issue. No action is needed — the service will restore automatically.

Cause 5: Firmware Corruption (Rare)

If a device never comes back online after a factory reset and re-pair, and the LED shows unusual patterns, an OTA firmware update may have been interrupted by a power cut. Contact TS Smart Home support through Account > Help > Contact Support in the app, providing your device model and the LED pattern you are seeing.

Preventing Future Disconnections

• Use a stable 2.4 GHz network — it has better range and reliability for IoT devices than 5 GHz.
• Keep your router firmware updated — router bugs sometimes cause device disconnections.
• Consider a mesh Wi-Fi system for large homes — consistent coverage prevents weak signal dropouts.
• Enable push notifications — get alerted the moment a device goes offline.
