ᐅ Ground floor hallway push-button control -> Hue motion sensor

Hey,

maybe someone here has a solution:

In the ground floor hallway, there are push-button switches at two locations (living room door, main entrance) and upstairs (stair landing). Now I would like to install the mentioned sensor on the ground floor. Normally, the switches stay "ON" so that the light fixture can be controlled. But push-buttons return to their original position and only send a pulse. Does that still count as a permanent "ON"? So that the hallway light can be controlled automatically via Alexa or the Hue motion sensor? Or what would need to be done to make it work as desired?

The same applies to the upstairs hallway. There is a push-button switch at three points (stairs, bathroom, bedroom) plus other push-button switches on the ground floor (as described). The plan is to have spotlights in the upstairs ceiling. Possibly controlled by a motion sensor or only via Alexa voice command. What is the best way to implement this? I have read about a Shelly relay, but there apparently is also a similar relay working over Zigbee...

Side question: At the stairway (quarter turn), there is a wall lamp before the corner going upstairs and another one halfway along the longer flight of stairs. How would you most sensibly control these? Currently, I would say the lower wall lamp is controlled from the ground floor, the second wall lamp from upstairs. When going up, you press the switch for upstairs and the second wall lamp and the upstairs hallway light come on. The first wall lamp lights up when entering the ground floor hallway from the living room. The ground floor hallway light is switched off when leaving the stairs using the upstairs switch for the ground floor.

Here I wonder how this can be combined with the Alexa/Hue setup.

Or the two wall lamps are controlled separately with a multi-way circuit (stair landing and upstairs).

Thank you for your opinions!

Exactly, the light sources and sensor are controlled via the bridge. Ideally, the switches shouldn’t be removed.

I just had the idea to use a flat “lampshade” and place a short Hue strip behind it—virtually invisible—so there would be a switchable LED light source. The ceiling light and staircase light could each be controlled individually via Alexa. They would only need to be permanently ON. What you could do—with the bypass, as you mentioned.

I just had the idea to use a flat "lampshade" and place a short Hue strip behind it – practically invisible – so there would be a switchable LED light source. You could control the ceiling lamp and the stair lamp individually with Alexa. You would just need to keep power constantly ON. Which, as you said, you could probably achieve by bridging.

But the Hue strip has a very long power cable. I think I’m imagining it incorrectly. You can just use the regular Hue bulbs for that, right?
There are also Hue wall lights (of course, the look has to match) or you could also use standard fixtures with sockets and simply put Hue bulbs in them.

Oh, of course... you’re my hero...

Hue also comes as wall lamps... ready to use. I’ve always gone for the finished flat LED lamps that have a fixed light source built in... so not Hue lamps.
The only thing left would be to bridge the constant "ON" state.

You could insert a profile into the existing vertical slot and attach an LED strip inside it. The only thing left would be to conceal the wiring neatly. For example, the power supply could be installed flush with the wall, possibly with an access panel for maintenance. The strip connection would be located at the bottom on stair level or below the stringer of the short side of the staircase.

Anyone have any ideas?

Unfortunately, there isn’t much variety in terms of appearance, but the ones I’ve seen were actually okay.

If only the two switches are involved, it’s a minor change to make. You can also install Hue switches. They would still be controllable that way.

I did this for my neighbor, but only afterward so it would be perfectly straight. You can simply get a U-shaped profile with frosted glass. At one point behind the slot, it should be a bit deeper/wider so all the cables, including the transformer, fit inside. From there, run them through an empty conduit below the stair steps to a power outlet.

True, the selection isn’t great... and most options are either exterior lights or extremely expensive, like the “Liane.”

Currently, there are no switches for the two staircase lights, only the cable running to the distribution board.

I’m exactly thinking of a U-profile like that, with frosted glass, so the light shines continuously and the individual LEDs aren’t visible.

Having a deeper/wider space behind the slot will probably be problematic, since it’s only a 17.5cm (7 inches) exterior wall due to the external thermal insulation composite system (ETICS).
You mean in the last sentence, the cable "plug -> transformer connection" inside the conduit below the step. The plug would then stick out of the wall by a few centimeters (inches) and connect directly into the box? Is that how I should imagine it?
