Installing the Hive hardware was straight-forward because my existing controller had a standard backplate and so I didn’t have to change any wiring. The trouble came when trying to setup an account because when you ring the number on the included voucher no-one seems to understand the process for self-installed units. After I eventually got it sorted I was told there is an alternative way which doesn’t involve going round in circles with various sales/tech support etc phone lines:-
When you order from Amazon there is a voucher code on the box. If then visit https://www.hivehome.com/shop/cart and enter the voucher code in. It will then allow you to create an online account.
This should have been included with the voucher code because it seems a much more straight-forward approach. Unfortunately before I could use this I was already setup but I’m pinning it here for reference.
