Yep, that's basically what I had in mind.
If I was developing the Tibber app myself, I'd add the Refresh capability so that it could be additionally refreshed on demand. It refreshes the values every two hours by default.
There's also a bug (or missing feature?) where the current energy consumption is incorrectly reported as the being the same as the current price.
I hacked out a modified version of the code that adds these two features. I can't test the energy reporting (it reports as null with the demo key), so one of you guys can hopefully give it a shot.
