Fixed a few things in my #eink energy monitor.

Now actually understands BST (🤭), also deals with negative pricing properly.

I also added a gradient (graydient?) To make it look slightly nicer.

OK, I didn't expect electricity prices to approach NEGATIVE 10p/kWh!

Might have to do some rejigging of my code. After being paid to cook a roast dinner 😄

@hugh @Edent I’m on Agile and the closest thing I have to a battery is a hot water tank and a storage heater. At least currently it’s significantly cheaper even if you don’t have much load that can be shifted around.

@hugh @Edent car now fully charged, washing done, dishwasher done, ebike charged, power tools all charged, laptops all charged, immersion heater finished, time for another cup of tea?

@jon @Edent Interesting. I'm on Tracker which averages out the evening peak prices.

I'll do a comparison over the last year to see if Agile would have been significantly cheaper.

I don't have storage heaters - panel radiators and an electric shower (the immersion heater is used for...not much). So it's difficult to shift load.

@jon This isn't perfect because of the way the tariffs changed - I can probably improve it.

But it doesn't seem clear. From December when the tariffs started changing, I'd have been better off on Agile.

But over the rest of the year Tracker was a better option, I suspect because of those high peak time prices

@hugh I think a big factor for me is that I’m almost always out for most of the evening peak, I’ll rarely start cooking until 7:30 or so.

@jon Yeah, that'd do it. I WFH most of the time so I'd really need a battery to offset some of these peaks.

@hugh I also work from home, I’m just generally out 6pm to 8pm, which happily coincides with high costs. I do know several people who aren’t and are still seeing a benefit though.
