i am a newbie in HA and i would like to ask about groups.
Simplest task - to group 3 binary sensors in group and then check every sensor state in Node Red at once (with one node)?
Of course i can do something like this
I think like most automation platforms Node-Red is event driven. So I’d make three event: state nodes that look at each sensor individually then check if your condition is met with a current state node or a chain of multiple.
Those events: state nodes only work when the entity monitored changes state. An event.
