Using smart devices like Honeywell smart thermostat, you are likely to spend a large amount of your time ensuring that everything works correctly with your devices connected. So, facing thermostat connection problems there is no need to check the WiFi network, probably your smart device requires a new software update to solve the problems.
Most Honeywell smart thermostats have trouble connecting to a wireless network from time to time, to solve the issue make sure you download the correct Honeywell app and that both your mobile phone and the Honeywell Wi-Fi thermostat are linked to the same hotspot network providing an internet connection.
Besides, make sure that your Wi-Fi network is working on the 2.4GHz band and that there are not too many devices’ interference on the same Wi-Fi network as the Honeywell smart thermostat system is only compatible with the 2.4GHz band of your Wi-Fi router, and Honeywell Thermostat is Robust Thermostat Barring.
Honeywell smart thermostats
Honeywell has an extensive product portfolio, including its smart thermostat line. Smart thermostat device works similarly to your standard thermostats but with some major differences to increase efficiency.
For a start, the Honeywell WiFi thermostat is much more effective in controlling the desired temperature. It also lets you connect to iOS or Android devices and control the functions by tapping the LCD screen via modem or router connections.
Several models can anticipate the temperature changes in your area. By limiting heat, a more efficient heating system can run less. Generally, the Honeywell thermostat proposes an owner-decreased energy saving and reduced energy bills.
Internet connectivity issue on your Honeywell thermostat
For the relevant work, your Honeywell WiFi thermostat should be connected to your computer or any mobile device.
Some connections may fail due to an unintentional error on the Wi-Fi router, this can happen without any fault in the software system. If you are experiencing problems with your WiFi networks, it might make sense to exclude them.
The most common Honeywell thermostat problems are caused not only by the Wi-Fi network but also by the recent update of the device. It downloads the most recent update approximately every two weeks, so by keeping the application recently updated, you might avoid about 80% of minor faults occurring in Honeywell WiFi thermostat connection problems.
Honeywell WiFi thermostat connection problems
When you face connection issues with your Honeywell WiFi thermostat, primarily ensure you use the correct Honeywell app, download the recent updates, and check whether your thermostat uses the same Wi-Fi network as your smartphone.
Rather often, the troubles of connections come with the old update. To avoid this issue, check for recent updates on Apple App Store or Google Play Store.
The most common issue and the possible solution are listed above, to see that most thermostat connection problems are easily fixed within a few minutes.
Wi-Fi network is not found
Searching for the necessary home Wi-Fi network, your Honeywell Wi-Fi thermostat cannot find a Wi-Fi connection. You cannot find the network name in the suggested list of networks.
To solve the issue, ensure your home router has a power supply and your Wi-Fi SSID is not hidden.
Most Wi-Fi routers broadcast your network name by default settings and there is no need additionally to open it only if you didn’t hide it earlier for security matters. If repeating scanning gave no results, you might enter all settings of the security protocols of your network name manually.
In case of the hidden Wi-Fi, you should follow the steps to enter your network details and get a Wi-Fi thermostat connection. Inserting the password and user name, be careful to avoid mistypes. A wrong network name, password, authentication, or encryption internet protocol entered here will keep your t-stat.
Network parameters changed
When you buy a new router, its network security settings should be also changed, and the Wi-Fi thermostat connection fails. Find it in the menu and change the Wi-Fi network name and password.
Renew your smartphone’s mobile data and insert the password one more time. If you receive the message ‘invalid password’, try to rest the router. Some models might need a hard reset to get back to the factory settings to correct the network.
A router might need a reboot
Honeywell wireless thermostat connectivity issues might be caused by other devices working on the same shared network.
Make sure your wireless home router uses Dynamic Host Configuration Protocol (DHCP). If it doesn’t use, contact your local provider.
Unfortunately, rather often we face such internet connection issues using Honeywell devices when several home wireless devices are connected to the 2,4GHz band while others might be capable with different bands.
Most routers nowadays provide two bands (5GHz and 2.4GHz). So, in case there are too many connections, link other devices to the 5GHz band or click to “forget” other devices. Too much strain on your internet, resulting in troubles in connections.
You might also restart your router to clear working memory out, to get a Wi-Fi connection to a known-clean point.
What does it mean too many connections?
The max number of routers you use depends entirely on the device. The router is rated for handling an optimum bandwidth and certain devices. Contact the support for a wireless connection in case you need to raise that limit. They can also provide a selection of other options suited to your needs.
The thermostat is far from your router
Smart household devices and microwave ovens might cause the wireless signal to break, resulting in Honeywell wireless thermostat troubles.
To avoid this issue, replace the Wi-Fi router closer to the Honeywell thermostat. Or there is another possibility to get a brand-new router with a wider range or buy a Wi-Fi booster that can push the signal further.
Defective Access Point
Wi-Fi thermostat connection problems might be caused by multi-path signals between your router and t-stat, even if your network is at the full strength. Besides, interfering devices might impact network traffic.
There is no need to provide an additional Wi-Fi setup option, moving the router closer to the thermostat avoids this issue with your mobile Hotpoint. If it doesn’t work, and the cause is not the thermostat, switch your device to a different router.
In case your Honeywell thermostat keeps having trouble connecting to the Wi-Fi, the issue may be with the damaged or broken thermostat. Older versions of thermostats seem available for only transmitting the power of the thermostat but have low signals, not enough for reaching most routers.
Or you may also upgrade your system by replacing the Ethernet cables as they might be worn out.
Honeywell thermostats are maintained constantly (24 × 7). In case your router does not require any advanced security settings, try to reboot the device. If the device doesn’t work, contact the Honeywell service.
Solving the issues with the Honeywell Wi-Fi thermostat, you might face a defective furnace. Wi-Fi thermostat furnace supplies the internal power of 24 volts AC. This energy reaches the Wi-Fi thermostat through the wiring from the furnace to the Honeywell Wi-Fi. In case of noise, interrupting and broken voltage, the Honeywell home cooling device often fails.
To fix this issue, the voltage of the air conditioner and the Wi-Fi thermostat should be 24 volts. If not, contact a furnace repair technician to troubleshoot the power circuitry.
The thermostat keeps losing connection
You have already tried to fix Honeywell WiFi thermostat connection problems with a wireless router, Internet provider, and location of your wireless devices and even checked the issues with a furnace but still get the thermostat disconnected due to losing connection, what else might be the cause?
There is an option called a recovery mode that might help to solve the issues with your Honeywell Wi-Fi thermostat. You may find this mode in the preferred settings “Smart Response Technology” and turn it on.
We listed other common issues when the thermostat loses the wireless connection.
Temporarily unavailable Internet service
In case your Internet service is temporarily unavailable, you will face with loose WiFi connection. Try connecting to another service and if the issue remains, notify your internet service provider about the problem.
Probably your Internet provider has temporary faults on their side.
E02 and E43 Error Messages
Some Honeywell thermostats might lose the network connection or cannot be initiated because of the reasons on the provider’s side. Try rebooting your router, wait for changes, or contact the service manager to solve the issue with your Honeywell home device.
The router lost power
Your wireless router might lose power supply and cannot transmit the signals to your mobile hotspot or Honeywell home thermostat.
To solve the issue, verify the power cable and electricity supply in your home in general.
The modem lost power
In case your modem loses power, verify whether it receives the supply.
The DSL modem and your wireless router are not in the same box. But all of them should receive enough power supply for proper functioning. In case of interrupting transmissions, you may practice rebooting, but in case of modem power loss continues, you’d better contact the service center or get a new device.
Check the lights on the access point, wireless router, and modem as well, if you found any red or blinking lights, they could indicate a problem.
Internet channel too busy
Even the most advanced internet speed can handle a minimal volume of internet usage. The Honeywell thermostat can become a bit difficult to connect to, or even impossible when connected to an older system. Maybe your device has been restarted without any effect. Eventually, it will be possible to determine how many Internet users there are.
Try disconnecting the thermostat in several minutes or so. There are no single-zone thermostats. The Honeywell thermostat might be able to work with other devices if you try a different Wi-Fi channel.
How do I fix the connection failure on my Honeywell thermostat?
