Interesting. I only emailed them yesterday. I'll await their reply and let you know what they say!It shouldn’t be necessary as a SMETS2 meter should never lose its connection to the DCC. Not all suppliers can accept DCC data but that is a different issue and not related to the SMETS2 meter type. One of the key ’advantages’ of SMETS2 is that the DCC is supposed to make switching suppliers a non event.
