Connecting the Honeywell Home RTH6580WF to WiFi Internet

WiFi thermostats and other internet compatible home devices all require the same two basic steps to connect the device directly to the internet: First step, use Wifi on your computer or mobile device to connect directly to the device’s built in “home” menu. Second, use the device’s built in home menu displayed on your computer or mobile device to allow the thermostat (or device) to your home network.

The thermostat manual is a good source (“Connecting to your Wi-Fi network” on page 10), but here is a short version:

      1. After performing a factory reset, connect your computer or mobile device’s wi-fi directly to the thermostat’s WiFi which will have the name “NewThermostat_123456 (the number will vary).
      2. If you are asked to specify a home, public or office network, select Home Network.
      3. When your computer (mobile device) is connected to “NewThermostat_123456” use your browser to connect to http://129.168.1.1
      4. On the page that is displayed, select the network to which you want to connect the thermostat and you will be prompted to enter the network password.
      5. While the connection is in process, your thermostat will flash Wait for up to 3 minutes. When the
        connection is successful, the display will show Wi-Fi Setup Connection Success and the Wi-Fi signal strength will appear in the top-right corner. After about 60 seconds, the home screen will
        then appear and Register at Total Connect will flash until registration is complete.
      6. Connection Failure? or Honeywell Error E02 (wrong password)? Oh No! To resolve this, read the next section

Fix the Honeywell Thermostat E02 Connection Failure with the TP-Link N300 Extender

Honeywell Thermostat connection failures are blamed mostly on the following:

      • (Incompatible) letters, spaces or special characters in either the network name or WiFi password
      • Wrong WiFi Password
      • Incompatible modem or internet router
      • Using WiFi encryption other than WPA2
      • Not using a 802.11b/g/n and 2.4Ghz WiFi connection. It should be noted that newer internet gateways both a 2.4Ghz connection that is compatible with the Honeywell Home Thermostat and also a secondary 5Ghz connection that is not compatible with the Honeywell Home thermostat.
      • Finally, Honeywell is aware of an inexplicable gateway incompatibility that can be resolved with an additional hub…

Using a $10-$20 TP-Link N300 Extender as a compatible “Honeywell Thermostat hub”

If you have a gateway or router that is incompatible with the Honeywell Home thermostat, then a $10 WiFi “extender” can provide a compatible 2.4Ghz WPA2 connection instead. The TP-Link N300 extender (TL-WA855RE) cost is about $15-$20 new and has been available for as little as $10 used. It can be quickly and easily set up to work with your existing router/gateway in a few minutes following these steps:

      1. Plug the TP-Link N300 into a power outlet.
      2. Press the WPS button on the TP-Link then press the WPS button on your internet router/gateway. This pairs the two devices and transfers the same password in your router/gateway to the TP-link N300 WiFi extender.
      3. The TP-link will now share the name of your router/gateway, followed by “_EXT”.
      4. Then, when configuring the Honeywell Home Thermostat (RTH6580WF) you will connect it directly to TP-Link Extender (_EXT) rather than your router/gateway and voilà, the WiFi extension is now working as a hub for your Honeywell Home Thermostat.
