Connectivity challenges

Even if you’ve planned your network well and considered all the factors listed above, you may still have a hard time connecting some devices. Here’s a list of ways to overcome the issue.


We recommend reading through this section before attempting to fix a connection problem. We’ve listed potential solutions in sequence, but you may find a better solution for your specific case as you read.

Even if you’ve planned your network well and considered all the factors listed above, you may still have a hard time connecting some devices. Here’s a list of ways to overcome the issue:

First, perform the basic checks, then try the following fixes. If necessary, refer to the detailed user guide available at

  • Check if the controller is in connection mode.
  • Make sure the thermostat is attempting to connect to the same channel as the controller. If this isn’t the case, set the thermostat to “Auto” mode.
  • Exit the connection menu and access it again. Now, try to establish the connection once more.
  • Disable the controller’s Zigbee network by selecting the “Exit this network” option. Then recreate the entire network.
  • Reinstall the controller in a room that’s more centrally located or has fewer barriers.

If none of these fixes help you establish the connection, there are other means to do so. Keep in mind that Maestro’s mesh network operates in an environment where different factors can influence its performance.

  • The more devices you add, the better your network coverage will be. If you replace all the thermostats in your home with Maestro thermostats, the distance between the devices will be smaller and it will be easier to relay signals around barriers. However, if there are few devices in the network, it may be more difficult to establish connections.
  • Your home’s structure or contents can represent barriers when trying to establish connections. Steel beams, thick or dense walls, solid doors, a refrigerator or water heater are examples of potential connection barriers.
  • Wireless communication signal and electromagnetic field saturation can also impact the ability to establish connections. Imagine a conversation in a noisy place. Even if the person with whom you are speaking is talking loudly, you’ll have difficulty hearing them. The same applies to wireless devices. Some signals may even come from your neighbours. Just think about how many Wi-Fi networks you see from your home when you access your cell phone settings. The following devices contribute to signal saturation:
    • Wi-Fi routers
    • Cellular phones
    • Laptops and tablets
    • Microwave ovens
    • Baby monitors
    • Fluorescent lamps
    • Wireless video game controllers
    • Wireless and connected devices (speakers, smart TVs, security cameras, etc.)
    • Low-quality or defective electronic devices that pollute the environment by emitting electromagnetic fields
  • In our model home, it’s easy to position the controller in a central location. However, if your home is long or unusual in shape, it may be more difficult to make some connections..

Now that we understand the environmental factors that affect connectivity, let’s see how to overcome these challenges.

  • Set your Wi-Fi network to the 5 GHz band. Most Wi-Fi routers operate on the 2.4 GHz or 5 GHz band. Zigbee transmitters operate on the 2.4 GHz band. If your Wi-Fi network operates on the 2.4 GHz band, change it to the 5 GHz band to reduce noise on the 2.4 GHz band.
  • Give your controller some space. If your controller is located right next to your Wi-Fi router or another connected device, the interference could be significant. It’s a bit like choosing the table right next to the speakers at a nightclub. Try to keep noise sources away from the controller.
  • If you still can’t get two devices to connect, add signal repeaters (product code: SMREPETZB) or signal amplifiers (product code: SMAMPLIZB) to reduce communication distances or bypass barriers.
    • These products plug into a wall outlet, so it’s easy to add them and even move them around for optimal results.
    • Start by placing the repeater or amplifier in a spot halfway between the two devices you are trying to connect.
    • If there’s a barrier between the two devices (e.g., a refrigerator), be sure to choose a location that allows the signal to bypass the obstacle. As a reference, think of how a ball rebounds off the cushions of a pool table.
    • If the connection issue occurs between two relatively close devices with few barriers between them, a signal repeater may be enough.
    • If you have trouble connecting multiple devices over long distances in the presence of many communication barriers, a signal amplifier may be required.

In a very limited number of cases, it may not be possible to establish a connection between two devices that are close to each other or directly visible in a clear signal path. Here are a few reasons why this may occur:

  • Because antennas don’t have the same transmission force in all directions, the devices could be positioned at a weaker transmission angle.
  • Since the signal between the devices takes the form of a wave, the devices could be positioned between two waves, making the signal weak.

Regardless of the situation, adding a repeater or amplifier is likely to solve the problem.
