No. Up to 3 tariffs can be set for each day but these will be replicated for each day and cannot be operated on individual days. It is very difficult to supply a product that meets every energy supplier's tariffs without it becoming overly complicated in terms of the tariff setup; however we will certainly take this into account for the future.
We suggest maybe taking some kind of average for the costs across tariffs and then entering this accordingly. Off course this does not affect the actual energy readings which are unaffected by tariffs.
