I am rather new at Node-red (as in I installed it yesterday) so this is probably extremely simple, but I can't for the life of me figure it out..
I am trying to set up some simple presence monitoring logic.
I am pulling the state of home/away from openhab using the openhab-in node, getting a simple on/off
What I want to do is the following:
2 people.
If neither is home, then check if guests is set to on/off and based on that take action.
If one of us is home, then skip any further checks, and take another action.
I can figure out how to use a switch to check for each person: if home then action 1, if not then action 2.
But I can't figure out how to check if both person 1 and person 2 is set to off, then check guests, if also off then action 3
Or how to do If any of these 3 is set to on, then action 4

Assuming all the information is held within the same message, you could do it with a switch node followed by a switch node. Or by using a function node with a javascript if this AND that type statement (google for the correct syntax)
If the information isn’t within the same message you need to get it there, you could use a join node, or store the data in memory. This has come up a lot in the past couple of days. There’s and example here [Output two attributes in the template](https://discourse.nodered.org/t/output-two-attributes-in-the-template/5983/6)
and you can read the docs within the working with function part of the documentation

Thanks 🙂 the Join node is what made it work for me. I assume this can be done more efficiently, but it achieves what I wanted 🙂
