I would like to have an enhance Home Away mode:

User can set on/off in a random way: during a certain period, set on/off with a random period (say 3 - 16 minutes) and in a random interval (say every 30 - 55 minutes). I believe this is useful for home security if you want to turn on some lights randomly in the night. One example is like this: between 5:45pm and 6am next day, for every 30 to 40 minutes (randomly), turn the power on for 5 to 8 minutes (randomly).

I would also like to have an easy way of setting on/off time. The current way of doing it is very tedious if you need to set a dozen of timing points. It could have a tabular form where user can select multiple on/off timing in one go.
