I have now taken part in 4 trials with a target of 0.1 kWh to save. On the first 3 trials, with a target of 0.1 kWh, I didn't go out of my way to do anything different, and on 2 occasions, I saved 0.09 kWh earning me 27p on each occasion and the other was 0.07 kWh earning 21p.
So on my latest trial 24/1/23 I really tried hard, I sat in the dark with no lights, no heating, no TV etc. The only power being used was the Internet and the led's on the oven and microwave and low and behold my results came back as a target 0.1 kWh and I saved 0.09 kWh earning me 27p.
Something seriously wrong with OVO's monitoring and recording ability.
