gchiu: This has current pricing http://www.em6live.co.nz/PlanningRegion.aspx?planningregion=lsi
But is there an archive of what prices were?
I just want to correlate their prices with Flick's.
I've decided to go the SMS way to control my hot water power so need to get some scripts running to send SMS, and monitor power, and send SMS alerts to my phone if power goes up too high.
Nope, but you can grab it from this site and record it. Remember live prices won't match the reconciled prices later.
Why would you want to actively control your hot water? That'd be almost as bad as Powershop. I turned my hot water off 5pm one Wednesday and forgot about it until Thursday 9pm. General use (dishes) plus six adult showers and there was still plenty of hot water left, with a regular sized tank. I figure a basic timer that turns the tank on between 3am and 7am is probably fine for many, and if it's not then a boost at 3pm or so when prices usually dip.
