Related Post: Condition to Reset Dim Levels based on Time of Day.
Ended up figuring this out (I think) on a GE/Jasko ZW3008 w/ Vera ID#19 and ZWAVE ID#6. Basically 2 actions to set the brightness to 25%:
Run Lua – This sets it up from the Vera perspective. So Vera initiated actions work.
Device Action – This sets it up from the device / Zwave perspective. So manual button initiated actions work (including sensor trigger).
Note here I used the value ‘24’, since the valid range is 0 to 99, corresponding to (n-1) as is typical with computer language indexing. So, if you want 25%, 25 - 1 = 24.
Have some complex logic to determine if (a) Night Mode is active, (b) device is currently powered off, and © house mode is either Home or Night. Then also have logic to set back to 100% during all other times if the device is powered off. So this doesnt auto-dim or brighten if it is already on and set, and resets to 100% on key lighting fixtures when you are walking around the house prior to going to bed. The 30% is so that you are not woken up (completely) when you stumble to the bathroom at night!
