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.

> Big Timer is (probably) the best-ever timing node for Node-Red, providing a general purpose timer as well as  handling summer/winter correctly as well as (importantly) lighting up time (for which you should provide longitude and latitude). After all...
