I have impression what logical operations in "Respond to event" criteria do not work correctly or not all devices and their parameters are useful for this. E.g. I tried to combine two conditions in the criteria: if Motion sensor tripped AND brightness sensor is lower than (a digit) execute the command (switch the light on). I tried for for the second condition several different things and it seem to me what the second condition is just ignored. Has anyone an experience in Advanced Events with complicate criteria?
