'Smart' wifi 2 way light switches?

[Acuity31]

Bit of a minefield looking for something that might work.
My living room has a ceiling light and 2 x 1 gang 2 way switches on either side.
I'm looking to replace them for smart switches/Google assistant compatible and likely do the same to other most frequently used lights in the house.

The 'master' switch has a perm live going to comm, 2 browns and the light switch live going to one way, and a couple others going to two way terminals, plus 3 neutrals terminated together.
The second switch has only 1 brown in comm, light switch live in one way IIRC and a signal wire in 2way.

Does anything on the market exist which will maintain the 2way control of both switches, with wifi, ideally without fitting a capacitor? Note that only the main switch has the 3 neutrals, the other switch has none.
Thanks

I used a physical smart light switch on one , and a battery operated smart on the other end of our kitchen, hall, and garage. Master and slave affair. They all work fine. Wired up as a single affair, not the usual method of double switching.
They are all tuya based, and operate though milliwave sensors as well.

not as good, but smart bulbs are pretty cheap these days too

These have been in for about 6 years.

Aren't those one way though, so would make the other switch dead

Yes, but wire as single with pass through, and use a second battery operated one as the second switch... master and slave as above in my previous .

I use one switch as the actual switch, and the other as a main powered remote that tells Home Assistant to switch the other switch, might be an option depending on what systems you're using.


Some relays can use a 240v signal as the switch signal, meaning you can leave your existing switches in place, and fit a relay in the light fitting using the switched live from the light switches as the signal, and connected to the live and neutral that you almost certainly have in the light fitting. I know the Sonoff Zigbee relays can definitely do this, don't know about WiFi ones specifically but I'd be surprised if Shelly don't do a relay that can do it.

Edit: Shelly 1 Mini diagram appears to show exactly what you want

Smart bulbs and either voice control or motion/presence sensors fitted in most rooms.
I've only got one smart "switch" for indoors lighting - a Shelly 1 controlling the transformer for the kitchen cabinet LED strips. Another Shelly does the garden outside light.

The hallways and landing are switched by Tapo motion sensors, as is the bathroom.
The dining room has several motion sensors.
Bedrooms and lounge are all voice-controlled using Alexa. Alexa can also override the areas with motion sensors.

Home Assistant ties everything together, and adds some automations. Not strictly necessary for the lighting though.
