Before you will be able to register your tank with your Mixergy account, the tank must first be installed and connected to the internet.
Ensure you are entering the 25-character mixdevice number, and not the MX number. This is printed on a white sticker on the side of your tank.
If the above doesn't work, check the connection of your tank.
If this does not resolve the issue, call our Homeowners & Residents line on 01865 595 875.
Hours: Monday to Friday, 09:00 – 17:00.
