Connect your tank to the internet (1.0 controller)
Your Mixergy tank needs an internet connection to work with the Mixergy App. If your tank was already online when it was installed, you don't need to do anything here. These steps are for tanks that haven't been connected yet.
Check you have a 1.0 controller
The 1.0 controller is a white box mounted on your tank with a large X logo on the front. The connection label sits on the bottom of the controller.
If your controller is a plain white box marked "Mixergy" and "Smart controller", you have a 2.0 controller. Follow Connect your tank to the internet (2.0 controller) instead.
This applies whether you have a Mixergy X, Solar X, iHP X or Cube X.

Before you start
- Download the Mixergy App from the App Store or Google Play.
- Open the app, tap Create Account and enter your details. If your address doesn't appear (common in new developments), type it in manually.
- Open the verification email, click the link and return to the app.
When the app asks for your Mixdevice code, scan the QR code or enter the code manually. You'll find both on the label on the bottom of the controller.
Connect your tank
There are two setups for the 1.0 controller. If a network cable runs directly from your controller to your router, you have an Ethernet setup. If you have a TP-Link plug in the wall with a cable running to your controller, you have a TP-Link setup. If you're not sure which you have, please contact your installer.
Ethernet Connection
What an ethernet setup looks like
- An Ethernet cable runs directly from the 1.0 Controller on the tank to a router, switch, or wall plate
- No powerline adapters are used
- The tank connects automatically once your Wi-Fi network is live
If the Ethernet connection is working, the Wi-Fi light on the tank will turn blue.

Please contact your installer or housing manager if you can see an Ethernet cable plugged into your router, your Wi-Fi is working, but there is no blue light on the Wi-Fi on the Gauge.
TP-Link Adapter
The TP-Link kit sends your internet connection through your home's electrical wiring, from a plug near your router to the plug near your tank. Your installer should usually set this up, but in some cases you may need to do it yourself.
Step 1: Plug or check the TP-Link in and connect to your router

- Plug or check the TP-Link is into a standard wall socket by your tank and another is near your router. Avoid surge-protected strips and extension leads, as both block the powerline signal.
- Plug or check an Ethernet cable is running from your Wi-Fi router to the TP-Link near it.
- Check the LEDs on the TP-Link are lit (Power, Ethernet, Data).
- If all the lights are lit, check the Wi-Fi symbol on the Gauge is blue. If it is, your tank is connected.
If it's not working, move on to Step 2. Please allow up to 5 minutes to check if your Wi-Fi symbol turns blue before trying Step 2 onwards.
Step 2: Re-power up your Mixergy tank
If the LEDs on the TP-Link are off or showing red, power the Mixergy tank of at the Gauge, then unplug and re-plug the TP-Link, then power the tank back on.
See this article to see how to turn off the tank using the Gauge.
Step 3: Pair the TP-Link with your tank
Press Pair on both the TP-Link near your router and the TP-Link near your tank.
- Press the Pair button on the TP-Link adapter (2)
- Within 2 minutes, press the Pair button on the tank controller (1). This is inside the controller box (you may need a pen or small tool)
- Hold each button for about 1–2 seconds
Once paired, the system will then automatically establish a connection.

Step 4: Check the connection lights
Look at the lights on the TP-Link plug:
- Top light (Power): shows the adapter is on
- Bottom light (Router): shows connection to your router
- Middle light (Tank): shows connection to your tank
When all three are on (typically green), your setup is complete.
If it doesn't take, please try the process up to 3 times.
Step 5: Let the system settle
Wait up to 2 minutes for everything to fully connect, check the Wi-Fi symbol is blue on the Gauge, and your tank should appear in the Mixergy App.
