Smart Meter - Turning on and off again

Had our Smart Meter installed 6 days ago, was working after 24hrs however just the gas was showing. Today the meter seems to keep turning itself on and off again (even though plugged in and charging) and when it is on it’s showing - ‘waiting for data’
Any ideas? Do we have a duff??

Just to be clear, what you’re referring to is the In Home Display (IHD) rather than the smart meter.

There are a number of threads on these forums about the issue however, including the one Allanr linked above.
