I have been sent this message from Tesla that indicates that a certain type of smart meter is incompatible with a Powerwall installation
We are keen to book a Smart Meter installation as we have Economy 7, a Powerwall 2 and two Tesla EVs
Here is the script from the letter.

Subject: Important information about your smart meter
Dear Powerwall owner,
We have received reports that, under some circumstances, there can be an incompatibility issue between the Tesla Powerwall storage system and the Landis+Gyr E470 100mm smart meter. In some cases this may result in inaccurate utility meter readings; the impact varies but could be up to +/- 5kWh per day on some sites.
Tesla Powerwall is certified to all appropriate standards for home storage systems and the problem only appears to occur with this particular model of Landis+Gyr meter. All other meters tested, including another model of Landis+Gyr meter, are unaffected. Where the meter has been replaced, no further issues have occurred.
