Initially when major spikes happen it is normally noticed NZ wide so just for simplicity sake an average will be worked out - depending on the API and how we can integrate it (it is our first time dealing with Pushbullet + IFTTT) we'll look at doing localised notifications. Might at the start look at doing a NI and SI average with the Pushbullet notification linking to the site for further information (will be mobile and data friendly).
NI and SI can sometimes be significantly different, especially if there are problems with the NI/SI cable, but that's not always the cause. Maybe a few times a year.
How many of you are actually on the split peak / off peak rates Flick offer?
By default you're not put on this tariff type, you maybe going through a lot of pain changing your lifestyle but not actually on the plan that rewards it.
They do not clearly list anywhere on their website or your bill the tarriff type you need to work it out form what is being charged....
In Wellington at least you don't get a choice, AFAIK. You pay market rates for power and the line charge is lower off peak. You can go to a low user plan that has lower daily fees.
