LED control: two inputs - 100% from the switch, 10% from the motion sensor

    Welcome,

    I would like to make a night light using 'normal' lighting.
    Is there a module that, using one input, runs the light at 100% (scene 1) and the other input runs the same light at 10% (scene 2)? A switch on the wall would be connected to the first input and a motion sensor to the second input.
    The easiest way to do this would probably be to switch on scene 2 "remotely", i.e. the motion sensor sends a signal to the "control panel" (e.g. home assistant) and this would switch the scenes already controlling the module.
    However, I would prefer to do this as "offline" as possible.
    As far as the installation is concerned, it is only in the process of being designed, so any wiring can be laid. The lighting will probably be LED.

    If you have a regulated power supply, this can be handled by a switch (relay) and 2 resistors or a potentiometer.
    Think about what should happen when 2 signals come in at the same time, do you need some kind of self-timed switch-off (other than the time of sensor operation)?
    Another option on which anything can be done is a microcontroller, the proverbial Arduino.
    As for off-the-shelf modules, maybe your colleagues can suggest something else.
    And also write what you mean by:

    12V Leds, 230V Leds, some individually controllable RGB?

    Thanks for the reply.
    I would prefer some kind of ready made module that will also allow me to easily adjust the intensity of the light.
    They will be white leds, without colour adjustment. I don't know yet whether 12V or 230V.

    It's only when you've made up your mind that you can look for a module.
    12V strips are easy to adjust, you reduce the voltage - they glow dimmer. The 230 ones tend to have a built-in power supply and not all give you the possibility of adjustment, so take that into account.

    Hi,
    You could embrace this - e.g. using an LED module with dimming function and two inputs (e.g. Zamel Supla ROW-02M). Then one button activates 100% and the other sets the scene to 10%.

    Thanks @LaserGrawer, that's closer to what I'm looking for. But I think this supla just doesn't support dimming.
    A ZigBee version of the module would be good.
    I found some OXT ZigBee SWTZ25 dimmer that has two circuits. The question is whether it is possible to control one output with both buttons, just by changing scenes.

    Maybe @ElektrodaBot can suggest something?
