Hi @Michael15 ,

I need to identify your meter first. Please post photos of it so I can check what you have.

Ok thanks. In that case, give this tool a spin: https://smart-meter-help.ovoenergy.com .

I may have found the problem,  the mobile meter had no batteries in it.  I've just put 2 in, hoping this helps 

A flashing WAN light is a good thing, @Michael15:

Is the WAN Flashing, On or Off? 

If the light is flashing, the meter is connected to the WAN. Please check how many times the light flashes between pauses.

One flash between pauses means very low signal, five means great signal. If the light is solid, there's no WAN.

Here’s some things to check, if your meter has no or poor WAN:

1. How strong is the mobile phone signal next to your meter?

2. Is there anything metallic in the way of the meter which could be moved?

3. If the meter has something metallic blocking the signal - for instance a mirror or an ironing board - then moving this may solve the problem.

4. Is your electricity meter in a metal box (e.g a metal meter cupboard)? 

5. Is your electricity meter in a basement, or is it partially enclosed (e.g in a closed cupboard under the stairs)?

Thanks Tim, this is the best reply *****
