I’m not sure if you have made a mistake with the numbers in your examples, but it doesn’t make sense to me.
Maybe show a real screen shot of the Flow you are creating so we can understand what you are doing?
The Object > IF > Action in Homey is the WHEN card in the app of the application of the device. In your way of thinking this would result in
WHEN the lamp is being switched off
THEN switch it on.
It is more use full to use a trigger like WHEN it is eight o’clock or WHEN the motion sensor is detecting motion.
WHEN time is 20:00
THEN switch group-livingroom-lamps on
PS: Homey advanced flow does not have nodes, but charts. It looks like you are use to object oriented. Advanced flows are just a graphical way of presenting normal flow, plus some extra’s.
So maybe it is better to start with normal flows.
I am getting that. I think I’ll have to give up and send it back. It’s no more advanced than using shortcuts in Homekit and I think I can do more with that.
You can create groups within Flows, you just add each device to the Action section.
So if you want any one of the lights to turn on the other lights then add the three When cards and attach them to the three Action cards that turn the lights on.
You can also add the And cards to check if the light is off first.
In your example you don’t specify what is being turned on.
