I've been a member for a while now and have learnt a lot just by reading through everyones posts and replies and think that this site has been a valuable tool for all involved with C_Bus. I'm having a problem with a Light level sensor that i am using to remote trigger a scene in c-touch and would appreciate some feedback !!! The sensor is in Network A and the c-touch is on Local. I originally had the sensor setup on the CA application but was unsure wether this was OK as i was using an ON/OFF command from the sensor so i am using a lighting application. Target set at 500 and margain of 200. 6 loads are being controlled by the scene. (PE Control ON) which is triggered when the sensor is at 100% (400 lux i am assuming!). 3 loads are switched off at 11.00pm via a schedule. 3 loads are switched off by the scene (PE Control OFF) which is triggered when the sensor is at 0% (600 lux i am assuming!). This all seems to work fine when i perform a test but next morning the lights that switch off at 11.00pm are for some unknown reason turning back on!! There are no external lights that affect the sensor but maybe i have my targets and margains set incorrectly. Has anyone had a setup similar to this ? If all else fails i will use logic to lock out the lights that keep coming on but am curious to what i am doing wrong Cheers Brad
