Thanks for the reply. I am still thinking that thru and once I understand the idea will drop a note if there are any questions.

Thanks both for your time and effort. I have actually simplified things a bit with the diagram. As mentioned earlier there are a few physical limitations. Let me list those:

Step/Switch 1 - is in a casing that is shared with 3 other light switches. No space at all for Shelly to fit in, unless new bigger casing is installed. Rather not mess with it at all.

Step/Switch 3 - has much more space. But it is on a place where would be exposed to kids rapidly turning on/off as it switches lights down the stairs , while kids would be after the light on the same floor. Assuming not a great environment for Shelly as quick on/off cycles might burn it. Does that make sense?

That floor area would be a great candidate for Shelly / sensor integration. But that is a separate topic.

Step/Switch 2 - rarely used, plenty of space for Shelly. But a confusing to setup, if possible at all.

Light casing - a bit crammed for what I'd like usually, but might be able to squeeze in Shelly relay. Might be the only viable option at the end...

Hope that makes sense.

There is another possibility for the left switch.

Just to have mentioned

Brown From L1 at L

Blue from L2 at O

L1 at SW1

L2 at SW2

and a wire from C at SX

Thanks I think that is pretty much the standard setup with 2 physical switches in place. And it is a great suggestion.

Thanks - got your idea! You are looking at this issue from a mechanical perspective. This will lead to more complicated electrical solutions…

Yeah we are constrained most of the times by environment we live in:)!

IMHO, this would be quite simple:

Shelly 1 (Shelly 1L not necessary) arranged in box with SWL/L/N.

SWL connected to SW of Shelly.

L to pin L and I of Shelly.

N to pin N of Shelly.

Lamp wire (previously at SWL) to pin O of Shelly.

Button type: Toggle or Edge

Hope this helps…

Thanks thgoebel. Sorry my diagram might be misleading. Box with SWL/L/N is actually where the light bulb(s) are connected. Which is very busy already and I'd like to avoid putting Shelly 1l in it. The easiest place to put the shelly 1l at the moment is in switch 2 (in red box on the diagram). Just wonder if Shelly 1L would work there and what ports should I use?

I think I have a solution but can't test it.

But it would be easier at the first switch .

Here's the idea

At first switch

Remove Phase and Black from switch

Connect them (so will be Phase at switch 2)

At second switch

Brown needs to be split in two

- one at SW1 the other at SW2

Black from first switch at L from Shelly

O from Shelly at the Grey (Left side from switch)

Button Type edge

Thanks for your advise SebMai, but that wouldn't that render switch 1 redundant? I'd still like all 3 switches to operate, but also have the software control as well.

I have a bit of a 'complicated' setup and couldn't find an answer to my query yet. Hope someone can share some ideas.

Light bulb(s) connected to 3 switches. Looking to put a Shelly 1L inside the middle ('intermediary') switch seems like the easiest route (below in red), in terms of effort and space to fit in the shelly relay.

As per the diagram, L1 and L2 can be live input & output depending on the situation.

So I am basically trying to replace the physical button ('intermediary' switch in the scheme above) with a software one (Shelly app), while still allowing all physical button to continue operating as usual. Which I think (hope?) is possible.

Still cannot figure out what Shelly ports should I connect 2 in and 2 out wires and what mode should I set the ports to.

Thanks,
