Missing method for creating/updating a tariff

[immccc]

Hi,

First of all, thank you very much for this library and for your effort in providing an open way to interact with Ohme chargers! I genuinely don't understand why the company is so reluctant to publish an OpenAPI spec and let users manage their own chargers as they see fit. But anyway, I’ll stop ranting and get to the actual issue 😆

I noticed that the library is missing a function to create custom tariffs, which could be really useful in various cases:

• Entering prices manually per day and hour is quite tedious from the mobile app.
• Some custom tariffs get updated frequently, even daily.

In my case, I built a simple tool to be run via cron to update a tariff that changes every day. I extended your library to support that, and I thought this snippet might help if you're considering adding more general-purpose tariff functionality to the client:

Best wishes,

Thanks for raising this request - I share your frustration with the lack of an OpenAPI spec. Hopefully one day!

Out of interest, what can you achieve with a custom tariff that isn't possible with the price cap function?

Totally happy to integrate your changes, its just something I've never used. My energy provider integrates with Ohme and sets the charge slots automatically.

The point is, my tariff updates daily, so if I want to see accurate pricing or use smart charging when rates are at their lowest, I have to update it manually through the app daily and iterating each hour, which is quite inconvenient.

I was surprised not to find this tariff listed. Even though Ohme includes many Spanish tariffs (most of them, actually), this one is an official option, with regulated prices that are widely used for several reasons (the main one, in my opinion, being that prices are regulated and protected from market fluctuations).

Cheers,
I.
