Recently had smart meters installed (SMETS 2 Meter) the installer never left us the in home display so had to contact ovo who speedily sent out the Trio II display, there are no instructions with the device I've switched it on and recieve connecting to smart meter followed by meter not commissioned.
On the SMETS 2 meter the WAN and HAN light indicators are off no lights.
How do I go about resolving these issues.
