Dears, I want to use switch node do mutual exclusion on lighting(light A is on-- light B is off, light B is on--light A is off). However I don't know how to implement it with switch node. [light-a] BR, Chris

Think through the logic first: When lightA changes: if (lightA === true) lightB = false; When lightB changes: if (lightB === true) lightA = false;

Thanks. I see. Below is my flow with function node + switch node to implement.

Thank you. It looks cool. But I just want the mutual exclusion on light on(light A is on--light B is off, light B is on--light A is off) not light off. Another question is how to solve external input condition on switch node for mutual exclusion not only click function. [light] Below is my flow I …

OK, I understand. In your dashboard nodes 'light A' and 'light B' there is a configuration option which reads: if msg arrives on input, pass through to output I suggest you enable this option and see in awe what happens :wink: Kind regards, Urs.

Hey, I have been trying to get the mutually exclusive toggle buttons to work for a while, but there seems to be something else going on! A few times the looping nature of this solutions froze up the computer :smiley: Your code works in the editor as it should, but it doesn't show the change in das…

Hey, thank you for the pointer. It's exactly that - a radio button set - that I was looking for. The idea is that the user can select only one value to be used as a global variable later. It could be done with a drop-down list, but it adds one interaction. I have modified Urs-Eppenberger's flow t…
