A Zappi EV charger is blocking communication between the Smart Meter and Octopus

I had a new Zappi EV charger installed in December and it stopped communication of electric and gas usage from the smart meters. Octopus has tried changing the comms unit and moving it further away on a fly lead. The smart meters will communicate only while the Zappi is isolated from the main electricity supply.
Has anyone else had this problem?

No but you should put this on the myenergy forum - someone there may have seen something like this.


Thanks I will

Interesting EMC/EMI problem to be having!
