Welcome to the world of old houses and the challenges of blending modern technology with period aesthetics! You're definitely not alone in wanting to keep the charm of toggle switches while adding the convenience of wireless 3-way functionality.Here's the situation and some options you can explore

The Bad News (Probably):
Direct Replacement - Likely No

As of my knowledge cutoff (September 2021), there weren't any readily available, mass-produced wireless 3-way switch systems using traditional toggle switches directly. The demand simply isn't large enough for manufacturers to invest in that specific design.

The Good News (There are Solutions!)

You have a few avenues to explore, ranked roughly in order of complexity/expense:1.

Smart Bulbs with Smart Switch Covers (The Easiest and Often Best Solution)



How it Works

This is often the simplest and most cost-effective way to achieve your goal. You replace your existing bulbs with smart bulbs that are compatible with a smart home platform (e.g., Philips Hue, Sengled, LIFX, Wyze). Then, you get smart switch covers that fit over your existing toggle switches. The covers contain wireless buttons that control the smart bulbs directly.

Advantages

Easiest installation (essentially just changing bulbs and switch covers). Preserves the look of your existing toggle switches. Offers the most flexibility and control (dimming, color changing, scheduling, etc., if your smart bulbs support it). Relatively inexpensive.

Disadvantages

Relies on the smart bulbs being reliable. If they lose connection, you lose control. Requires a smart home hub (e.g., Philips Hue Bridge, SmartThings hub) for some systems. Some smart bulbs connect directly to Wi-Fi. Requires ensuring the original switch is always in the "on" position; the smart cover handles the on/off.

Examples



Philips Hue

(Requires Hue Bridge) Good quality, reliable, integrates with many platforms. Use with a switch cover designed to work with Hue.

Sengled

Can work with or without a hub (check the specific model). More affordable.

Lutron Caseta Smart Bulb Dimmer Kit with Smart Switch Remote

This is a good option. It is not a toggle switch, but the remote can be mounted over the existing switch to look like a switch plate and it can be programmed to work as a 3 way switch.

Important Considerations

Carefully measure your existing toggle switch plate to ensure the smart switch cover will fit properly. Make sure the smart bulb and switch cover are compatible.2.

Smart Relays/Modules Hidden Behind the Toggle Switch



How it Works

You install a smart relay module inside the electrical box behind the existing toggle switch. This module does the wireless communication and switching. Your toggle switch is wired into the module as a low-voltage trigger.

Advantages

Preserves the look of your existing toggle switches completely. More "traditional" wiring approach, controlling the power at the source (as opposed to relying on smart bulbs).

Disadvantages

More complex installation. Requires wiring knowledge and potentially an electrician. Requires space inside the electrical box, which can be a problem in older homes with shallow boxes. May require neutral wires, which are sometimes absent in older wiring. Requires a smart home hub for some systems. Finding modules that work reliably and are compatible with your smart home system can be a bit of research.

Examples



Shelly 1/1PM

Small, versatile, Wi-Fi enabled.

Inovelli Red Series Dimmer Switch (Used as a Relay)

More advanced features, but can be configured as a simple on/off relay. Z-Wave or Zigbee connectivity, so it needs a compatible hub.

Aeotec Nano Switch

Z-Wave, requires a hub.

Important Considerations

Check your electrical box size and wiring before purchasing. You must be comfortable working with electrical wiring or hire a qualified electrician. Ensure the module you choose is compatible with your smart home system (if you have one).3.

Combined Smart Relay and Toggle Switch (Rarest and Possibly Most Expensive)



How it Works

This would be a complete replacement for your existing switch, with a toggle-style switch on the front and a smart relay built-in.

Advantages

Combines the traditional aesthetic with the smart functionality.

Disadvantages

Extremely rare to find. The market is very small. Potentially very expensive if you can find one. Limited selection and features.

Where to Look

This is the hardest option. Start by searching specialty lighting and home automation suppliers, as well as custom electrical component manufacturers. Be prepared for a lot of searching and potentially contacting companies directly.4.

Consider a "Compromise" Toggle Switch

Some companies make smart switches with a slightly more "traditional" aesthetic than the standard decora paddle. While not exactly the same as a vintage toggle, they might be a good middle ground that's easier to find and install. Lutron Caseta is a good place to start.

Steps to Take


Assess Your Wiring

Open up your existing switch boxes and carefully examine the wiring. Note the number of wires, their colors, and whether you have a neutral wire (usually white). This is critical for determining compatibility with smart relays.2.

Consider Your Smart Home Ecosystem

Do you already have a smart home system (e.g., SmartThings, Hubitat, Home Assistant)? If so, choose a smart relay or bulb that is compatible.3.

Research and Compare

Read reviews, compare features, and check compatibility before purchasing anything.4.

Prioritize Safety

If you're not comfortable working with electrical wiring, hire a qualified electrician. Electricity is dangerous.

Recommendation:

I'd strongly recommend starting with option #1 (Smart Bulbs with Smart Switch Covers). It's the easiest, least intrusive, and often the most cost-effective solution. If that doesn't meet your needs, move on to option #2 (Smart Relays).Good luck, and happy renovating! I'm happy to answer any follow-up questions you might have. Just remember to always prioritize safety when working with electricity. Flag for review
