You have to set the brightness percentage in the rule. Mine were all defaulted at 45%. I set them to go to 90% on trigger (door open) and 25% or off (depending on which light) on trigger (door closed)
That doesn't work for me - any action that involves the Wink lights turns them off: Off = turn off; On = turn off; set percent = turn off; set percent and turn on (either order) = turn off. The state in the sensors page doesn't necessarily obey the rule
or reflect reality
Further oddness, in my current rule (set percent of two lights, then turn on), they both turn off, but one changes percent to zero, the other leaves it as it was. The sensors status page says they're both on, one at the percent it was on before, the other at zero.
Note I'm using the key fob to trigger the rule, if that matters. It's the only input-type sensor I have to experiment with
