Smart Meter Crashes

Does anyone else have a smart meter which crashes? Ours has done this at least 3 times now and the only way to reset seems to be unplug the power, let it run flat and then turn it on again after charging.

Might be easier to ask if anyone has one that works?

Mine froze once a few weeks ago. I got it to restart by holding the button on the back down for a while and its been OK ever since.
