In a normal Zigbee setup it would be possible to get a dedicated Zigbee repeater although most people get a simple and very cheap Zigbee smart power socket like this - https://www.ikea.com/gb/en/p/tradfri...tlet-00364477/
I believe this still may not help in this case because I believe all the Zigbee devices need to be configured as part of the same
'network' and you would not be able to add the standard Zigbee device to the smart meter network. Perhaps PurePlanet can confirm this.
So, it seems hypothetically it would be possible but it might require the smart meter manufacturers to make a Zigbee repeater that can be officially joined to a customers smart meter HAN - Home Area Network. I have not been specifically looking but I strongly suspect that no such device yet exists.
Since likely many customers will have this problem I feel that the manufacturers need to address this and provide such a repeater solution.
Note: For security reasons the HAN used by smart meters only accepts devices that have been officially 'white listed' so generic Zigbee devices cannot be connected. They are supposed to allow the customer to connect their own devices as long as they are white listed, despite this some providers have been uncooperative and this is regarded as being in breach of the licensing terms for smart meters. (The whole point of smart meters is to facilitate connecting customer access devices.)
I hope Pureplanet are going to be more cooperative about customers wanting to connect CAD type devices. Some customers have had to take OVO Energy to OFGEM and BEIS to get them to behave properly.
