Newbie needs help! How to test if two states are ON, then trigger event?

General

Hello! I have, I think, a fairly simple task. I'm a newbie at NR though, and I'm finding it incredibly difficult to wrap my head around.

Essentially I have a lawn mower and sprinklers, and they should never be on at the same time.
Lawn mower gets priority over the sprinklers.

If sprinklers are on and lawn mower starts mowing -> turn off sprinklers
If lawn mower is on and sprinklers start sprinkling -> turn off sprinklers

Should be very easy, right? The lawn mower doesn't have a simple on/off (more like "mowing" or "parked" etc), so I had to create a rather large switch that takes various text inputs and maps them to ON/OFF accordingly.

So now I should be able to somehow determine if they are both running at the same time.. but how? I'm lost when it comes to comparing two messages.

Current status (not working):

[{"id":"b6c312ca.754b2","type":"join","z":"dc46be20.8e86","name":"","mode":"custom","build":"object","property":"payload","propertyType":"msg","key":"topic","joiner":"\\n","joinerType":"str","accumulate":true,"timeout":"","count":"2","reduceRight":false,"reduceExp":"","reduceInit":"","reduceInitType":"","reduceFixup":"","x":430,"y":200,"wires":[["f04be0bc.9601"]]}]

Bonus points if you can help solve the error on the Mower State, "Node-RED custom integration needs to be installed in Home Assistant for this node to function correctly." (it IS installed, and it has updated variables before!)

EDIT: I've figured it out, see below. Please comment on how to do it better! :slight_smile:

I guess I get the bonus points - I added a 1 sec delay before the event node and now it works. :man_shrugging:

I believe I got the flows working, but as a newbie I'd love some criticism so I can learn if there are better ways to do it. I feel like this was very 'round about'.

Maybe label your nodes so from a quick view you can see which path is for your mower and which is for your sprinkler.
