What Zigbee wall switches should I get?

Hi all,

I’ve recently purchased a new house and am living there currently. I’ve already removed the old light switches to get a good look at the wall switches.
I have a family that wants to use the light switch rockers, which is fine for me as long as it does not mess up the automations that I have set up.

I’m looking for zigbee wall switches, this can be the little relay modules that fit in the back of the socket, or light switches that do the job. Entering the world of light switches, I feel like an idiot, this is all new to me, but I’m learning a lot.
I seem to have a lot of what we call in the Netherlands hotel-switches. I can turn off-on the light downstairs from the switch nearby, or the one up the stairs as well. These seem to work independently. I have a few of these in the house.

I have no neutral wiring, it’s just the brown power wire with black switch wires.
Here’s an example I have for a double rocker switch:

So one of the rockers controls the lamp in the hallway, this is S1. However, two black switch wires are connected to S1. Then there’s S2 that only has a single black wire, this is the lamp next to the front door.

Are there any zigbee lightswitches or relay modules that support this “hotel switching” where a lamp has two switches that seem to work independent?
Here are two more images of the light switch I am talking about:


Greatly appreciate any guidance here!

You mean a cross circuit right?
Bosch Light Control 1 has this feature. It has two outputs and replaces the first switch. It can detect where the power is drown and switches the state of itself if necessary. It also measures energy.
The only problems are that it is proprietary zigbee, it is pricier than most manufacturers and you need the bosch hub for that, but at least it connects locally to home assistant. We have more than 30 devices including smoke detectors, water detectors, thermostats, cover control units and light control units and it is working great.

That one is 58 euro’s a pop, that’s a bit too much for my budget.
I’m thinking to just get rid of the cross circuit / hotel switch for some lamps and use the SONOFF switches. I’ll post my findings in this topic.

Where did you look?
