Nope, no such function! I actually bought this device because it is cheaper than the others that have this function.
That's why Digitec did a bad job!
But it's more of a gimmick that you rarely need, but it can also be interesting.

I've had it for a month and even after a long search I couldn't find this function - but for me it was more of a gimmick than an add-on, as I need the control for a terrarium lamp and the thing does a good job for that (also with automatic summer and winter time changeover).
