How to connect Mill heaters to Mesh Wifi

This article explains how you can connect Mill Wi-Fi heaters and other IoT devices to mesh networks such As AirTies Smart Wi-Fi by temporarily disabling the mesh.

Some IoT / smart home products will only connect to the 2.4 GHz frequency band, and this causes problems when connecting to mesh Wi-Fi networks that use a single network name (SSID).

Mill heaters come with a built-in Wi-Fi adapter that allows them to be managed using the mobile app Millheat. This adapter only supports the 2.4 GHz frequency band and the 802.11b/g/n Wi-Fi standards..

This causes issues when connecting to mesh Wi-Fi networks, which primarily use the newer standard 802.11ac. If the mobile phone that runs the Millheat app is connected to the 5 GHz network, adding a Mill heater to the same network may not be possible.*

One workaround for this this is to temporarily disable the mesh network. If you have a mesh network from AirTies, follow the steps below to install a Mill heater using the Millheat app.

1. Disable the mesh network (temporarily)

Turn off all AirTies access points except the one you have connected to your router by Ethernet cable. If you have a regular AirTies home pack, this means that two access points should be turned off. The power button is located on the back of each device.

2. Install the Millheat app

  1. If you haven’t already, install the Millheat app for Android or iOS on your mobile phone.
  2. Make sure your mobile phone is connected to Wi-Fi.

3. Add the Mill heater to the network

1. Make sure the Mill heater is turned on.

2. Start the Millheat app and select Add device.

Connect the Mill app to the network
Make sure the heater is also connected

3. Push the wifi button on the heater and continue.

Connect them to each other

4. Choose your product (in our example a wall-mounted heater).

Select your product from the options displayed

5. Select the correct model.

Select your model from the options displayed

Finally, add the password to your Wi-Fi network and make sure that the green Wi-Fi light on the heater is still flashing.

Connect to Wi-Fi

Wait for the app and the heater to connect to each other.

4. Re-enable the mesh network

Now you can turn on all the AirTies devices again, and the mesh network will work as before. Remember that mesh device startup takes a few minutes.

Tested with Millheat app version 3.2.6.
