Energy bill

The energy bill shows units and the rupee amount for today, this month, and last month.

Today starts at midnight on this device's clock. This month starts on the first. Last month is the full previous calendar month.

Units are the last reading minus the first reading of the energy key on each meter, then those meters are added. The widget does not subtract the smallest reading in the group from the largest. If you set the widget to sum the samples, each meter is summed and those sums are added. The amount is units times the tariff you enter, in rupees per unit.

Choose the energy key, the tariff, and the meters. An alias or a device type can select the meters.

Saving the readings is already done by the platform. This widget only prices the stored counter.
