Smart Meter display unit (PA1)

Hi,
I’m looking for a smart meter Home Display Unit similar to the photo. Scottish Power appear to be out of stock of these. I’m not 100% convinced that the one I have doesn’t work but it isn’t communicating to the new smart meter that has been installed. Suggestions welcome, but this is in clear view and only 3 metres from the meter. Also, I think the Home Display Unit, also known as an In House Display, would need to have been provided by Scottish Power.

Thanks,
James
