    Hello,
    I would like to prepare the external lighting of my house in such a way that the dusk sensor would switch on the lighting at, for example, 20% power and the motion sensor would switch it on at 100%.
    Unfortunately, I have not found any ready-made devices giving such possibilities.
    Do you have any ideas how to solve this?

    Ladies, anything is possible.
    It's just a matter of money and time...

    What power supplies, what sensors, what lamps?
    So far we know nothing.

    Lamps with LED bulbs, voltage 230V, for now without sensors - I have not yet started the circuit

    The logic and electronics part itself is relatively trivial. However, there is a catch in the form of LED lamps.... Can they work with a dimmer, because unfortunately most of these types of 230V ready-made lamps react poorly to phase control.

    for the lamps I bought bulbs that can work with a dimmer
    I am glad that it is trivial :-) because for me it is not....

    You could do something like a series-parallel control.
    You give a phase to a twilight sensor and from its output you go to a parallel connection of a phase regulator running at 20% and a motion sensor. When the motion sensor is inactive, the lamp is powered by the regulator and if the sensor is tripped, a bypass is created and full phase goes to the lamp.
    Alternatively, if the regulator cannot have phase fed to the output (or rather it can), then you would need to use NO/NC changeover contacts for the motion detector.

    Added after 3 [minutes]: .

    Possible alternative route. Driving this dimmer works somehow, it is often controlled by a potentiometer. You could plug into the control circuit of the controller and select the settings so that, without the motion sensor tripping, it works at 20%, and when the sensor triggers, a resistor of the selected value is switched on in parallel or in series (depending on whether the resistance needs to be increased or decreased). Only this could already be an interference with the phase controller itself.

    In the country where I currently live, lamps with this type of function are generally available in any building/home improvement shop. I can't believe that you can't buy this in Poland.

    I would use two circuits, a 12v circuit for leds (e.g. 4 watt) with a twilight sensor, they are small in size so they will fit into any lamp housing, and a second 230v circuit for a motion sensor.

    I recall something like this which, depending on the brightness, adjusted the light output to suit the conditions. I remember it worked with motion sensors, but it was mostly used in industrial applications. It probably has a Spectrum.

    Thanks for your help. I will try to do just that.

Topic summary

The discussion revolves around setting up outdoor lighting that utilizes both a dusk sensor for dimming at 20% power and a motion sensor for full brightness at 100%. Participants highlight the importance of selecting compatible LED bulbs that can work with dimmers, as many 230V LED lamps do not respond well to phase control. Suggestions include using a series-parallel control system to manage the power output based on sensor activation. Some participants recommend using separate circuits for the dusk and motion sensors, with a preference for 12V circuits for LEDs. The DALI interface from Mean Well is mentioned as a potential solution for controlling lighting scenarios. Overall, the conversation emphasizes the need for proper components and configurations to achieve the desired lighting setup.
