Time scheduled on/off automation request

Hello there, I have some computer fans and I would like to run these via some kind of on/off interval mode.

for example, for all week,
between 7:00 am and 12:00 pm fans are "off",
between 12:00 pm and 7:00 pm fans are "on" for 30 sec. between 30 min. interval,
between 7:00 pm and 7:00 am fans are "on" for 30 sec. between 15 min. interval.

How can I do this with nodes ?

Check out @scargill's Big Timer.

Other timing nodes are available :wink:


thanks all, I'm working on that nodes
