Thanks, great tip but… I don’t think they support the following complicated use cases out of the box? In Sweden we have: - Dynamic electricity price (monthly average kWh price) - unless fixed contract of course - Dynamic grid cost (flat fee plus based on kWh transferred) - Dynamic grid ”penalty” (average of 3 highest effect peaks in month \* extra penalty price per kWh) - Tax on above items ---

Mine works without ext power after boot up. I just put USB power in for 10 seconds, then i can remove it from the dongle after boot. ---

So tried to use the “Dynamic” pricing built in into Homey App. Unfortunately it can only handle 1 dynamic variable - spot price, and not additional and customized variables. Too bad… ---

I’m afraid the just (very) recently introduced dynamic price feature is still very basic, and probably initially aimed to the fairly simple dynamic tariffs in NL. I can recommend the original, [Power by the Hour app](https://community.homey.app/t/app-pro-power-by-the-hour-insights-per-hour-day-month-and-year/20535) for a 100%, to build price driven flows with.
