How to test the system

If you cannot log onto your Genius Hub, the following test will show which part of the login process is not working, and how to fix this.



Checking you have the correct credentials

  • When you try to log into the app, if you see the error message 'Incorrect username or password', this is due to the username or password being incorrect. 

    • The easiest way to fix this is clear both the username and password and try again. This is because some devices can auto-capitalise the first letter and so starting again lets you check each letter as you type it in.

Confirming the device is working

  • The first thing to try is logging in from scratch. 
    • On a mobile device running the app, force-close the app, then re-open it. On Android this can be done by getting all of the apps on screen (normally by pressing the 'square' button), then swiping the Genius Hub app off screen. On iOS double-click the home button so all of the apps appear on screen, then swipe the Genius Hub app off the screen.
    • On a web browser, close the tab. Open a new tab and navigate to the app. 
    • If this works, the app had either stored out of date information, or the device has removed some of the login information from the cache, stopping the device from authenticating with your Genius Hub.
  • If you can't log on after starting the app from afresh, try using another device (such as another mobile device with the app, or an 'incognito'/'private' window in the browser) try logging onto your system.
    • If you can log in on the second device, then the problem is with your main device.
    • For a mobile device running the app, uninstall and re-install the app. This will ensure that you have the latest app, and that there is no remnant data from previously which could interrupt the login process.

    • For a web-browser, clear the cache and site data for www.geniushub.co.ukand try logging in once more. 

      The app runs in most modern browsers, however it is developed in Google Chrome, and so if you are having problems we recommend you try in this browser.

Ensuring that the internet connection is working


Confirming the Genius Hub is powered on & connected

For the HUB-B

  • The Genius Hub has 2 cabled connections. 
  • The first to check is power.

    • Ensure that the power cable from the back of the Genius Hub is plugged into the power supply provided.

      Do not use a USB power from the Internet router as these do not output enough power to run the Genius Hub.

    • When the power cable is plugged in there should be a red light which turns orange inside the Genius Hub.

  • The second cable to check is the Ethernet cable. This should be plugged into the Genius Hub at one end and the main internet router at the other, ensuring the internet router is powered on.

    Whilst the Genius Hub may be using a Powerline Ethernet Adapater or similar most of the time, for this test we recommend using the main router to rule out any local networking problems.

    • When the power and Ethernet cables are correctly plugged in. you should see lights appear next to the Ethernet Cable on the Genius Hub.

For the HUB-C



  • Load up the My House page of the app.
  • Check to see if there are any errors reported in the 'System' tile at the top of the screen.
    • If so, look for the Genius Radiator Valve for this zone.
    • If there is an error with this device, click on the error to be guided through how to fix it.
  • If there are no errors, go to the radiator zone and override it to '4°C'.
    • This should be a significant amount below the set temperature.
  • The heating indicator for this zone should turn blue.
  • Click on the Main Menu.
    • Select 'Settings'.
    • Choose 'Devices'.
  • Locate your Genius Radiator Valve for this zone and click on the row to expand it. The setpoint should say 4°C.

    • If it displays an arrow to 4°C, you will need to wake up the Genius Radiator Valve by pressing once on the right )^) button. The time since last communication should return to near 00:00 and the setpoint should update.
  • The Genius Radiator Valve should now show 4°C on the screen if you wake it up.
    • If the device does not say 4°C, click on the device submenu (•••) in the app and choose 'Configure'.
    • Confirm that you want to proceed by pressing 'Configure'.
    • Now click on the device submenu (•••) and choose 'Ping' and confirm this.
    • Wake up the Genius Radiator Valve by pressing the right )^) button.
    • The time since last communication should return to near 00:00 and the setpoint should say 4°C.
  • Return to the My House page, and select the radiator zone once more.
  • Override it to '28°C'.
  • The heating indicator for this zone should turn orange.
  • Click on the Main Menu.
    • Select 'Settings'.
    • Choose 'Devices'.
  • Locate your Genius Radiator Valve for this zone and click on the row to expand it. The setpoint should say 28°C.

    • If it displays an arrow to 28°C, you will need to wake up the Genius Radiator Valve by pressing once on the right )^) button. The time since last communication should return to near 00:00 and the setpoint should update.
  • The Genius Radiator Valve should now show 4°C on the screen if you wake it up.
    • If the device does not say 28°C, click on the device submenu (•••) in the app and choose 'Configure'.
    • Confirm that you want to proceed by pressing 'Configure'.
    • Now click on the device submenu (•••) and choose 'Ping' and confirm this.
    • Wake up the Genius Radiator Valve by pressing the right )^) button.
    • The time since last communication should return to near 00:00 and the setpoint should say 28°C.
    • The fact that the Genius Radiator Valve displays 28°C, on the device and app shows that it is communicating correctly.

Confirming the boiler controller is working

The instructions below are for a Dual Channel Receiver, however your boiler may also be controlled by a Single Channel Receiver.

The notes will explain where this differs for testing.

  • Open the door on the Dual Channel Receiver and read from the labels on the inside of the door, which white button control the heating (it is normally the upper button).
  • Press and hold the relevant white button. The light should turn green to confirm that the Dual Channel Receiver is calling for heat. If you have a Single Channel Receiver Receiver, a green light should appear on the front.
    • The fact that the boiler controller shows a green light, shows that it is communicating and responding correctly.

    • If the light turns red and you have not configured the Dual Channel Receiver during this testing:
      • To fix this, click on the device submenu (•••) and choose 'Configure'.
      • Confirm that you want to proceed by pressing 'Configure'.
      • Now click on the device submenu (•••) and choose 'Ping' and confirm this.
      • The time since last communication should return to near 00:00.
      • Press the white button and the light should now turn green. If you have a Single Channel Receiver, the green light should appear now
    • If the light turns red and you have configured the Dual Channel Receiver during this testing:
      • See this article for re-adding the Dual Channel Receiver to your system.
      • See this article for re-adding the Single Channel Receiver to your system.
  • If the light on the Dual Channel Receiver turns green when you press the heating button, the zone valve should open and the boiler fire.
  • To check the zone valve is working, go to where the zone valves are located, this is normally next to the boiler. A zone valve is a silver metal box attached to a large brass valve in the pipework from the boiler, which has wires going to it. This shuts opens and closes the flow of water around your system based on when there is a call for heat.
    • On the side of the zone valve should be a lever. 
    • When you try to move the lever, if it is:
    • Difficult to move, then there is a problem with the zone valve or the wiring between the Dual Channel Receiver and zone valve. You should get a qualified plumber to look at and fix this.
    • Easy to move, then there is not a problem with the motor on the zone valve, but there is a problem wiring between zone valve and boiler, or a problem with the boiler. You should get a qualified plumber to look at and fix this. Alternatively, see this article for some common problems with the boiler which may be the cause of the problem.
  • If you have a Single Channel Receiver, you may have a combination boiler without zone valves.
    • In this case, when the light is green, the boiler should fire.
    • If the boiler does not fire, the boiler may need to be checked that it has power, suitable water pressure and no error codes on the front of the boiler. You should get a qualified plumber to look at and fix this. Alternatively, see this article for some common problems with the boiler which may be the cause of the problem.


Confirming the Genius Radiator Valve can open/shut off the flow of water

  • With the radiator zone overriden to 28°C, the zone orange on the app and the boiler running hot water should now start to flow around the system.
  • Wait 10 minutes and go to the radiator in question and press the right )>) button. You should see 28°C on the screen of the device.
  • Gently try to rotate the Genius Radiator Valve. The head should spin freely, but not leave the radiator.
    • The Genius Radiator Valve has fully retracted the plunger and in turn the pin is now free for let water pass.
    • If the Genius Radiator Valve is not turning freely, press the right )>) button once more and wait 10 minutes. It is possible the valve was asleep and has not had time to open yet.
  • The radiator nearest the Genius Radiator Valve (and the pipe beneath) should now start to heat up.

    • Be careful when checking the radiator as it may be very hot and burn if due care is not taken.

    • If the Genius Radiator Valve is turning easily but the radiator is not heating up, either the hot water has not been pumped this far from the boiler, in which case waiting a few minutes longer will fix this; or the pin in the valve body underneath the Genius Radiator Valve has seized.

    • The fact that the Genius Radiator Valve turns freely shows that it is working correctly.
    • If the radiator is still not heating up, the seized pin will have to be freed or the valve body replaced. To try to free the pin, remove the valve head from the radiator, and with a pair of pliers or end of a large spanner, gently work the pin on the valve body free. Be careful when doing this as if the valve body is in poor condition, it may cause the valve body to leak. Once the pin is free, remount the valve head. See this link for removing and remounting the Genius Radiator Valve.
      If it's not possible to free up the pin on the valve body, it will need to be replaced.
