Problems you may encounter while connecting your thermostat to the Internet
If you have a problem at any point during the process of connecting your thermostat to the Internet, the first thing to check is your C-wire connection. To do this, remove one of your thermostat's batteries and wait several seconds. If it loses power, your thermostat's C wire is not functioning properly. Consult your thermostat's Install Guide for instructions on proper C wire installation.
If your C wire is functioning and you're still having difficulty, read on:
- Back to TopI can't open http://192.168.10.1.
First, confirm that your thermostat is ready to connect by verifying that the yellow light on the left side of your thermostat display is blinking. If the yellow light isn't blinking, reset your thermostat by pressing the thermostat's MENU button, so that MATE appears on the left side of the display. Press MATE twice. When the yellow light (middle of the three) starts blinking, you're ready to connect.
If the web address still won't open, confirm that your computer or mobile device is connected to the thermostat's temporary wireless network. (For example: "thermostat-E1-2F-19.")
In addition, make sure you aren't running any firewall programs that prevent you from connecting to temporary networks. Refer to the instructions that came with your security software for how to temporarily disable this setting.
- Back to TopMy thermostat isn't displaying a five digit PIN.
Your thermostat shows its five digit PIN when it is in "provisioning" mode. That means it's ready to be connected to the Internet. To switch your thermostat into provisioning mode, press the MENU button. When "MATE" appears on the display, press it twice. After a moment your thermostat will return to provisioning mode – signified by a flashing yellow light (middle of the three) next to the display – and the five digit PIN will appear.
- Back to TopI attempted to set up a static IP, and it isn't working.
When you open the Advanced tab during the setup process, check to make sure the subnet mask listed there matches the subnet mask of your current network. In addition, make sure the thermostat is on the same subdomain as the router. (That is, if the router's domain is 10.0.1.2, the thermostat's domain should be something like 10.0.1.5.)
- Back to TopI entered my thermostat's IP address into the URL field of my browser, but my computer can't communicate with the thermostat.
Confirm that you have disconnected your computer from your thermostat's temporary wireless network, and reconnected it to your familiar home network. You should also verify that you have correctly entered the thermostat's IP address using the instructions in the Wireless Setup Guide. If your thermostat is far from your wireless Internet router, you may need to move the router closer to the thermostat. If the problem persists, reset the thermostat by lifting off its top cover and pressing the RESET button. If that doesn't work, try resetting your router.
- Back to TopI can't find my thermostat's UUID number.
Confirm that you have disconnected your computer from your thermostat's temporary wireless network, and reconnected it to your familiar home network.
- Back to TopAt the end of the setup process I received the message, "Cloud Status: Connection Error"
Unfortunately, something has gone wrong. Reset your thermostat and router, and repeat the setup process.
- Back to TopIn the manual connection process I don't see a place to enter the authentication key.
Usually this indicates the process has previously been run to completion. The next step is to perform a factory reset on the thermostat. Press Menu, then with one finger press and hold the middle of the thermostat screen. When the arrows appear, press the down arrow once. After the countdown is complete the thermostat will reset and you can restart the connection process from the beginning.
- Back to TopI've been waiting for my thermostat to connect to finish installation, but it never connects. What's wrong?
If you're manually setting up the thermostat and you've completed all the steps in the setup guide but the thermostat won't connect here are a few troubleshooting tips:
- Mistyped UUID – Did you type the UUID from the web page? If not try copy and paste to make sure you got it correctly.
- Firewalls, parental controls, and other internet blockers – Do you have anything that blocks traffic on your router? Some people have theirs set up to block unknown traffic, check with your home's tech guru to make sure the traffic is set to flow.
- Try a reset – Everything else correct? Try a reset: Remove the top cover and press the RESET button near the top left corner. Wait 60 seconds and then try again.

- Back to TopWhy bother setting a heating and cooling schedule?
Setting a schedule saves you money and energy. Many people fail to set heating and cooling schedules because their thermostats are just too difficult to operate. Your account, by contrast, offers an intuitive interface that makes setting your schedule a breeze.
- Back to TopWhat is ENERGY STAR®? Why should I follow its recommendations?
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. The program's purpose is to help us save money and protect the environment through energy efficient products and practices.
With the help of ENERGY STAR, Americans saved enough energy in 2010 alone to avoid greenhouse gas emissions equivalent to those from 33 million cars – all while saving nearly $18 billion on their utility bills.*
- Back to TopI forgot the password used for my account. How do I recover it?
Visit the Reset Password page. We'll email you a special link that will allow you to change your password. The link is only valid for 24 hours.
- Back to TopWhat is the Target Temperature?
It's the temperature your thermostat will keep your home at or near. If your home is in cooling mode, your cooling system will turn on if the temperature in your home rises above the target. If your home is in heating mode, your heating system will turn on if the temperature in your home falls below the target.
- Back to TopExplain the four Modes. What's the difference between Heat, Cool, Auto, and Off?
If your home is in Cool mode, your cooling system will turn on if the temperature in your home rises above the target. Cool mode is best for the summer months, when there's no chance you'll want your heat system activated. To protect your cooling equipment from possible damage, do not use Cool mode when the outdoor temperature is below 50°F/10°C.
If your home is in Heat mode, your heating system will turn on if the temperature in your home falls below the target. Heat mode is best for the winter months, when there's no chance you'll want your cool system activated.
If your home is in Auto mode, heating or cooling modes will be automatically activated within the range of your heating and cooling schedules. To protect your cooling equipment from possible damage, do not use Auto mode when the outdoor temperature is below 50°F/10°C.
If your home is in Off mode, you are not using your HVAC system to control your home's temperature.
- Back to TopWhat are my Fan settings for?
When your fan is set to Auto, it remains off until needed to circulate warm or cool air through your home. When your fan is set to On, it runs continuously, even if your HVAC system is not actively heating or cooling your home. Setting your fan to Auto is the more energy-efficient choice.
- Back to TopWhat does the Set Away button do?
Clicking on Set Away is an easy and convenient way to set your home to an energy-efficient temperature while you're away. Going back to your normal schedule is just as easy – click End Away when you return. You can change the thermostat's Away temperature on the Settings tab of the Thermostat page.
- Back to TopWhat does the Hold button do?
The Hold button maintains your home at its current target temperature even if a schedule change should occur. It's there in case you deviate from your usual routine – you're throwing a party in your home, for example, and don't want your home to shift into its overnight temperature setting. You can find the Hold button on the thermostat's Schedule tab on the Thermostat page.
But don't just set your thermostat to Hold and leave it there! You'll miss out on the savings and efficiency only a schedule can provide. Use the End Hold button on the thermostat's Temperature or Schedule tab on the Thermostat page to resume your normal schedule.
- Back to TopHow long does it take for changes I make on the website or mobile apps to take effect?
Changes you make to your thermostat settings from the website can take up to five minutes to take effect on your thermostat. For the mobile apps, changes should take effect immediately when you are connected to the same wireless network as your thermostat. Changes made from other wireless networks or from outside your home can take up to five minutes to take effect.
- Back to TopWhat happens if my thermostat goes offline?
Your thermostat will maintain the schedule you have set for it even when it's not connected to the Internet. To reconnect your thermostat:
- First check that your wireless router is working and you have access to the Internet. If your Internet connection or router is down, your thermostat will reconnect automatically when your Internet connection is restored.
- If that doesn't work, try resetting your thermostat. Remove the top cover and hold down the RESET button for a few seconds and then release. Your thermostat should reconnect after the reset is complete.
- If your thermostat still won't reconnect, check that your thermostat has power, as the wireless connection will not work on battery power alone. To test power, remove one of the batteries. If, after one minute, the thermostat is still functioning, then your thermostat has sufficient power. For help with power, please visit https://my.radiothermostat.com/rtcoa/support.html and click "Wiring".
- If none of the above steps resolves the issue, you should perform the setup process again. Start by pressing the thermostat's MENU button, so that MATE appears on the left side of the display. Press MATE twice. When the yellow light starts blinking, you're ready to continue with the setup process. You should consult the appropriate Setup Guide on the Support page.

Radius is compatible with iPhone 4 and later generations of iPhone devices with location services turned on and OS 4.3 or higher. Radius is not compatible with the iPad. Radius is also compatible with Android devices with location services enabled.
- Back to TopWhy is my runtime data unavailable?
Your thermostat collects data about when your heating or air conditioning system is operating. This data, called runtime, may not be reported due to the thermostat being offline, having a weak connection, or other thermostat errors. The most common reason your data may be missing is because your thermostat is currently offline or was offline during the time period being reviewed. For more information please see "What happens if my thermostat goes offline?"
