This is a working flow of my security light system of:
- 4 x PIRs, each powering a Sonoff
- 4 x security lights, each powered by a Sonoff
Why the decoupling and not just get 4 combined PIR/security lights? My use case is that I want to...
- position each PIR and each security light in their optimum positions - which is not necessarily in the same location
- enable using the PIR as a regular motion detector (will use a flow to do this)
- enable each PIR to power on/off more than one security light
- for both the PIRs and the lights to be able to independently "talk" MQTT.
The delay is set manually in each node (thanks to @Colin for the Trigger node suggestion - my first attempt had 2 extra nodes per PIR/light ughhh) and I'll try and get them all set from a global variable. The state of each PIR is saved in a per-PIR global variable (as is the light state as well, but that's in a different flow).
