Diagnosing Wi-Fi Issues
Some handy hints for troubleshooting a Wi-Fi connection

Check your connection

Use the WAKE / RESET button on the side (v2) or base (R3) of the unit to see the current connectivity status:
Click the WAKE / RESET button briefly to wake the unit!
Holding this button down longer than a few seconds will clear the Wi-Fi credentials.
  • Blinking green, then solid LIGHT BLUE (CYAN) for 5-10 seconds
    = the unit is already connected to a Wi-Fi network
  • Blinking green for 10-15 seconds, then blinking RED
    = failed connection. See possible causes below
  • Continuous blinking BLUE or PURPLE
    = not connected / waiting for WiFi credentials from the app. The the "Reconnect" page for details

Troubleshooting a failed connection

If a sensor that was previously connected, no longer connects to the network:
  • Power cycle your router / modem. Unplug for 30 seconds, then power it back up. After waiting for the Wi-Fi network to turn on (1-2 mins), test the connection as above.
  • Has your network name (SSID) or password been changed since the TankMate sensor was set up? If so, reconnect the sensor using the updated details.
TIP: use a phone or tablet to troubleshoot issues with a Wi-Fi password. Under your network settings, FORGET the selected network, and then connect again using your password.
Advanced wireless settings / firewall issues:
  • Note that TankMate sensors can only connect to 2.4GHz networks. Combined 2.4 / 5GHz networks are also supported
  • Certain networks may apply restrictions that limit network access for smart devices. Check your network security settings / advanced wireless settings in this case, or contact your service provider to troubleshoot the issue.
  • In some cases, setting up a guest network (2.4GHz) can be a good workaround for advanced network settings
  • The TankMate Wi-Fi sensor uses port 8883 to send data to the internet - ensure this is not restricted
