Have a Zappi 2 which I got from Octopus. My tariff ends in August (go Faster) and goes from about £600 to £1,500 !!!???
I know costs are bad but the thing that bugs me is that my current tariff has an off-peak from 20:30-01:30 which suits me, as as all my white goods are without timers and due to fire risks reported in recent years, I like to be awake when stuff like washing machines etc., are running. The new tariff, either Go or Intellegent, have peak time from 11:30 or 00:30, which sucks. The Zappi though, works fine and is geared for Solar & batteries too, which I want to install but waiting for the right time as right now prices are going ballistic (and cowboy installers proliferating…). Solar makes sense for me, as I work from home all week - haven’t seen an office for nearly 2.5 years now. Won’t live long enough to get the ROI, but savings these days are a waste of time. Spend it while you can is my new motto (or spend it and be damned…whatever?? )
