Use lux level to turn on light

Third party integrations Node-RED
1

I am starting with using Node Red in HA just today. I got a fibaro dimmer unit and a fibaro multisensor. I have a flow which turn on the light when the sensor senses movement and turns the light off after 10 minutes of no movement.

No I want to add a second part and that it only turn the light on when the lux leven of the sensor i below a certan value. I tried a trigger and a current_state block but cannot get it working. Can some one point me in the right direction ?

I know the trigger is not connected, but it is just for showing what block I tried.

Use a trigger-state node with the constraints motion is on and lux < min value.

The above might produce a weird result if the light being on makes the lux sensor go above the threshold and the light would still turn off even if there is movement.

I new to node red and maybe I think wrong. I am testing this flow:

I got this setting on the current_state item image

I would thought if the lux level would be below 10 I would get the debug msg 1 and if its above 10 I would get a debug msg 2. But I always get a debug msg 2.

Update the home-assistant nodes you have a version where half if logic isn’t fully loaded which could be causing the error
