My Dimplex Hub has stopped responding on WiFi & there is a Red power (lighting flash) LED lit up. The WiFi light lights up occasionally then goes back off.

A red power light means that the Hub is not able to connect to the internet.


In order to rectify this, please try resetting your DimplexHub by pressing the top red button on the back of the Hub.


If the power light goes red again once it has finished rebooting, you will need to change your Hub connection via the Dimplex Control App as follows:


  • Load the app
  • Press on your Hub
  • Press the three dots (...) on the top right hand side of the app
  • Press “Hub Settings”
  • Press  “Change Hub Connection”
  • Press the Bluetooth button on the Hub
  • Press "I Pressed The Bluetooth Button”
  • Press “Yes the Light Is Solid Blue”
  • Pair your phone to the Hub. You will then see a notification on your phone for a pairing request. The pin code is the pin on the back of the Hub
  • Press on Connection Type and select either WiFi or Ethernet
  • Press on the WiFi connection (if on WiFi) and it will scan the available WiFi.
  • Select your chosen WiFi.
  • If using the ethernet cable, simply select Ethernet
  • Ignore Proxy and IP and press Save Settings And Connect.
  • You will then be asked for the WiFi password (if on WiFi)
  • The app will then attempt to connect to the internet


If the power light is still red when connecting through ethernet, or is still red after checking your WiFi settings, please advise who your internet provider is and provide the GDID and Pin from the DimplexHub's data label.


If this does not work, and you are on WiFi, please check the following:


  • Ensure you are in range of the WiFi network
  • Ensure the password you entered is correct
  • Ensure the network you are trying to connect to is a 2.4GHz network.  If your internet router supports both 5GHz and 2.4GHz, please ensure the 2.4GHz band is enabled

If the 3 items above appear to be correct can we go through the next points

  • Please try to set up a wifi hotspot on your phone and then go through the steps of trying to connect the hub to that. If successful this would indicate an issue with the router and/or broadband provider.
  • If the wifi hotspot does work then the focus will have to turn to the router. There are 2 further things to check here but both would require you to go into the settings on your router - usually this is done by opening up a browser and going to the router's admin web page - please refer to the router's user manual or check their broadband provider's online help.
    1. Within the router settings please make sure the Wifi is operating at 2.4 GHz only
    2. Within the router settings you can also check to see what Wifi channel(s) the router is operating on. If this is set to 'Auto' then please try changing this to something like 'Channel 11' (rather than Auto).
    3. Within the router settings please also check what ports are being blocked/allowed. For the hub this is the following - 80, 443, 5671 & 5672
