I want SO BADLY to convert my switches to smart switches, but it feels impossible to find what i need. Good luck searching on Amazon, too. Search for Zigbee, and it will return page after page of zwave, proprietary, and other listings. It's impossible to wade through. I've tried and given up multiple times.

This is what i need that is evidently so difficult to find: 1. Zigbee 2. 3-way 3. Dimmable 4. Beige (almond?) Color

Any ideas?

I highly recommend buying some Zigbee switch modules [1] and wiring them up behind your regular light switches. They convert any light switch into a smart switch that can be controlled through your Zigbee network. (This can be dangerous, but just make sure you turn off the power first, wear gloves, and learn all about line, neutral, ground. Get a good multimeter and triple check everything.)

I'd recommend checking out some of the "smart relay" devices that let you reuse your existing light switches.

e.g. https://www.amazon.com/Compatible-SmartThings-Philips-ZBBrid... - this one says "2 way" but I'm pretty sure you can wire it up with two physical lightswitches to get the 3-way behavior that you're after. The wiring diagram on the amazon product page suggests as much.

I've personally used this Aeotec z-wave variant and it has worked well for me: https://www.amazon.com/gp/product/B06XC4CH98

For multi-way switches what I’ve usually done is wire one switch to the actual load (light) and a relay, and the other switches I pass the wire through as though the switch isn’t connected to the load and then use MQTT to provide the appropriate action. Probably not ideal, but it works and avoids sourcing specific relays and switches.

Check out the Shelly products. You can wire them in behind a standard wall switch, and they can talk to a local MQTT server instead of the cloud. Replace your on/off flick switch with a push button.

Shelly products are also UL-certified. This may be an important factor when it comes to home insurance should something go wrong in a fiery way.

I found the same thing. I was searching for air quality/CO2 monitors. It seemed that decent ones werent with zigbee.
