Scenario
1 Lux sensor
12 automation that refers to the ambient light value (all have the same high and low triggers)
Each time you want to change the Lux high or low value you need to change 12 automations.
Thinking is: you have 1 automation where you set the low and high value
This gets stored as a 1 or 0 or an ON or OFF “helper”
All automation that looks at the LUX value goes to the helper and validates if the helper is “ a 1 or 0 or a ON or OFF”
Issue Resolved
Create a helper a Binary Sensor where you set the lux value you want the on/off to change on= night where eg Lux is 10
Then in your automations look for the helper state when you define the WHEN Condition in all your Automations.
This enables you to set the LUX level switch as a helper and you can do a global adjust for lux level to switch automations.
If you have a single LUX sensor and you have areas that are darker in general in your house you can set a second helper with a different – higher value .
