Openhab Presence monitoring

General
1

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
and you can read the docs within the working with function part of the documentation

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