[Feature request] Add support for Greenley #182

Open enoch85 opened 8 months ago

enoch85 commented 8 months ago

Great integration! It's a shame I didn't find this sooner since this was/is exactly what I'm looking for. I ended up building my own equivalent by taking the spot price at the time my cars are smart charging (it's the cheapest), then calculate the difference in a function of different levels where I want to discharge the battery or not (BYD 11 kWh).

But enough about me.... and yeah, sorry about the highest price name. :)

It would be super cool if you could add support for Greneley in the same way as Tibber. That way everyone using Greenley could get their tariff with add-on charges etc.

In Home Assistant I currently use this to get the current price. Maybe one can get some inspiration from that?

Does Greenely have an open API we can connect to?

If you can use the existing sensor.greenely sensor from NodeRED, and create a function that outputs the standard strategy input format, it should not be too hard to use their tariff.

I don't think so, hence the workaround I posted.

That's already what I do more or less, but would be nice with built in support.
