ev.energy app goes further. It automatically turns charging on and off to optimise cost to get your car charged by the target time based on data from Octopus.
Thanks for this, not heard about this solution before so I've set it up.
I set it up several months ago, so I can’t quite remember. I just left it on the default settings and the charge periods it chooses match the lowest prices on the screen I see on the Octopus website when logged into my account page. I know this by looking at the history from the JuiceNet app that shows what my EO Mini Pro has been doing.
Excellent!Working on my personal dash still, mainly formatting/best UI now. As I said, not intending for it be smart or anything, just to sit on a tablet in the kitchen for quick viewing of rates, and via my phone in a nicer/prettier format than the apps I've seen.
And, more than anything, a little lockdown coding project! Haven't needed to fiddle with APIs/json queries before so it's been useful.
Simple, but there is no official API. I personally pull from TeslaFi, as I can quickly kill the API key if it became compromised. Also with the Tesla API you need to renew key every 45 days (code or manually), but no need with TeslaFi.

GET /v1/electricity-meter-points/{mpan}/
returns eg
{
"gsp": "_H",
"mpan": "2000024512368",
"profile_class": 1
}How often you going to be changing your tariff?
