I have been with OVO about a year and have a Smet1 meter fitted, I’m with electricity only as I’ve had a 2 year contract with Better energy for gas, the tariff with them was the best around BUT the tariff is coming to an end at the end of Jan 2019 and I’ve been doing manual readings monthly.
As a radio amateur I’m very aware that some radio amateurs have been refusing smart meters as they interfere with Shortwave, putting out a hash type (white noise) out, making it impossible to use the receiver/transceiver.
For me as far as I can see I have no issues with mine, I do with VDSL but that’s another story.
I am now looking for a dual fuel fixed tariff so searching for the best and cheapest in my area, if I move from OVO I'll be paying a penalty but that’s not a problem.
What I would like to know from others in my hobby who have actual experience (not guessers) Is the technology any different with smet1 or smet2 i.e; less or more likely to interfere with shortwave, usually better screening helps with stuff like this.
