1. An apparatus for tinting one or more tintable windows, the apparatus comprising at least one controller that is configured to:
operatively couple to one or more sensors comprising a temperature sensor;
operatively couple to the one or more tintable windows;
determine a drive parameter based at least in part on data from the one or more sensors;
compare the drive parameter with sets of stored power profiles arranged in an n-dimensional data structure of data elements, each data element of the data elements corresponding to a respective power profile of stored power profiles and each dimension of the n-dimensional data structure corresponding to a different drive parameter, wherein a first dimension corresponds to target transmissivity values and a second dimension corresponds to current transmissivity values; and
utilize-the comparison to identify a stored power profile of the stored power profiles that corresponds to the drive parameter, wherein the stored power profile identified is utilized to alter tint of the one or more tintable windows.
