Dear Zendure team, I am French living in Spain. I know that for the moment you don't sell officially here, yet you have a number of electricity providers listed for the dynamic (or other ) tarifs.
You even were able to link the tarif to the esios website where the day-ahead tarif published everyday is the correct market data ! Congratulations on that.
The last step that you are missing is to offer the option to select the regulated tarif for Spain, also called PVPC, which is the one you list + certain taxes and tolls. While we can add manually a % to the variable tarif, as you offer the option, the tolls are varying depending on the time period of the day, so if just adding a %, the price during the solar hours will be quite different from the real PVPC.
I hope you can list this tarif soon as it would help us to maximize automatically our savings (and it can be a good source for Zenki to take decisions to charge or discharge the battery).
Thanks !
Marc
