Node red, timers

Fredrik_Jacobsson · August 26, 2019, 12:31pm

Hi
I try to create a flow that will control my laptop charger via a wall plug.
This is what I want to achive.
Monitor the laptop on-time, done via the network. If laptop is connected it is on!
When the elapsed time of the laptop on-time has reached a set time, i.e the laptop can be turned on and off several times before the elapsed set time is reached.
Then the wall plug/charger shall be turned on and be on for a set time.
After the wall plug on-time is reached it shall start all over again, i.e both the timers shall be reset.

I can’t get this to work, have tried both with nodes and function.
I don’t find any handy nodes to use.
And I’m new to javascript and have a hard time. I’m used with C.
It is possible to get a function in Node red to be clocked, like in C?
