Multi-input flows, node-red or something else?

[EricD183 (Eric B Dalquist)]

I’m trying to figure out the best way to implement a bunch of automations that need to read the state of multiple sensors and if Node Red is a good option.

I’ve done several flows that are based on a single input or state and it is quite easy. However it isn’t clicking how to do something like:

• Trigger on change of any of:
  • Lux Sensor 1
  • Lux Sensor 2
  • Sunset/Sunrise
• If Average Lux is less than 50 OR (after sunset AND before sunrise) then do X

Another example

• Trigger on change of any of:
  • Door 1
  • Door 2
  • Humidity Sensor
• If door 1 or door 2 open turn off switch
• If humidity < 65 turn off switch
• If door 1 and door 2 closed for at least 5 minutes and humidity > 65 turn on switch

I’m mostly struggling with the single-input nature of nodes which makes me unsure how to do something like averaging two inputs.

Also it seems like a lot of duplication as I need an events:state and current state node for each sensor I want to trigger and perform logic on.

Wow, thanks for the amazing examples, I’ll go grok them and see if I can get a better handle on the how to set up these flows.
