Updating an 'at'

[franc]

Hi, I'm Relatively new to fhem and have come across the first things I did had to do in a ugly way. I have a set of LIFX Wifi light bulbs did I am controlling via PIR sensor. My first setup easy thing to turn lights on when i went in to a room and have the lights in the other rooms turn off, then I wanted to do something fancy.

   
• If I go in to a room the light turns on and stays on for 30 minutes
• If I go in to another room then the lights in the room did turn on, but the time-out for the lights in the first room is reduce to 2 minutes

I'm currently doing this with some custom perl and by deleting and recreating the 'at' that turns the lights off Does anyone have any better suggestions? thanks

have a look at 'modify'.

it allows you to modify any fhem device including at.

I probably should have explained the bits I found tricky.

The custom perl checks to see if if the 'at' is already set for a time earlier than time()+delay and if it is then does nothing, if not it modifies the 'at'. Without this check the 'at' keeps getting pushed further in to the future
