"Locking" lights on

[NeilP 0]

Hi,  I have a number of Fibaro Dimmer 2 units that are triggered by Fibaro motion sensors. When the sensor is breached they turn off and when the sensor returns to safe they turn off. I need a way of "locking the lights on when we don't want the motion sensor safe to turn them off.

 

I'm currently using scene activation (3 presses of a momentary switch) to change a variable to do this but it seems overly complicated.   

Is there a better way of achieving this please

I think you want this functionality, because someteimes when you enter the room, the lights go on, and you just sit in your chair, grab your beer, and start to watch the TV. Then for a couple of minutes you don't make any motion, so the sensors "thinks" you are not there, and it turns off the lights..Is this the reason that you are doing this locking ?

If so, i have been playing with some better solution for this, and realized, that there's not a real perfect solution for presence detection by PIR sensors. If you really want some real presence detection you need to find another type of sensors, like thermo sensors, or there are some solutions for BLE detection of your phone etc, but i never used them.

What worked for me was to play a little bit with the turn off window time and the sensor sensitivity.

I have increaed the TurnOff window time to a value that suited my needs, for me 15 min was good.  Then i increased the sensitivity of the sensor to maximum, so the sensor gets triggered by every little motion.

I think this is the simpliest way in my opinion. If you are in a still position like a piece of brick for more than 15 minutes, than you probably slept away, or you are dead. In both cases there's no need of light.
