In this article, I'm going to show you the complete Homekit dimmer switches guide, the necessary ecosystem, comparison of the top brands, why I chose Leviton, installation, pairing instructions, and solutions to common problems.
This guide reflects my research and experience with the technology without any sponsors. I'm linking to every product for your convenience with my amazon affiliate links. I update this guide regularly.
Router
If you are thinking about controlling your devices with Apple HomeKit, the first thing you need to consider is your wifi system. If you don't have a strong signal throughout the home, you will face connection issues with
ANY
device. If you look at any bad review for any smart home device, the number one complaint is connection issues. You need a mesh system to limit the number of connection issues. I use a
Netgear Orbi system, and it works flawlessly with a strong signal throughout my home. The
RBK20w
is the best value in the Orbi family, but there are many
great choices,
Apple TV, HomePod, or iPad
You certainly don't need an
Apple TV
or HomePod to start using your HomeKit devices, but you need at least one of them to control your devices remotely. I started with a couple of
light switches
and a
smart thermostat, but soon after, I bought the Apple TV and activated it as a home hub through the settings. You can also use an iPad as a hub if you leave it at home all the time. Apple TV is the cheapest way to get remote access.
I chose the HomeKit environment for its ease and the increased security compared to the alternatives.
Neutral Wire
If you have a newer home, building code requires the use of neutral wires throughout your home. You will need a neutral wire for most switches and dimmers that work without a hub. If you don't have the neutral wire, your options are limited to the more expensive Lutron Caseta devices and smart bridge that don't require the neutral.
When I started this smart home journey, there were only two key players, Lutron and Leviton. There were other brands, but they didn't work with Homekit.
What tipped the scale for me with Leviton was the freedom from hubs. With Leviton, I can buy one unit and connect it to my network, and it's ready to go. The switches and dimmers are also a better value, and you can buy different color covers and switch plates for them. The 5-year warranty was a plus vs. the one year with Lutron
The ride with Leviton hasn't been smooth, but with their latest firmware update, these devices work flawlessly.
Dimmers
Dimmers are great for dimmable lights, and you can customize the minimum, maximum, and default brightness levels in the Leviton app. You don't need the app to start, but it will give you the ability to update your firmware and select the bulb type.
Dimmers will make LED bulbs a bit noisier when not operating at full brightness. Bulbs will emanate a high-frequency noise, but the sound is only noticeable in extremely quiet environments. Some bulbs will be louder than others, so I recommend you experiment with different brands of bulbs.
Do not use dimmers with ceiling fans. It will make them unbearably louder, and damage to the fan may occur. You can find Homkit Fans from
hunter, but they are costly. I use standard fans with the Leviton Switch since I don't mess with the fan speed. I typically keep my ceiling fans at low or medium speed to maximize quietness and comfort.
Switches
Switches will work with any lighting situation and fans so long as you don't need fan speed control. LED will operate at 100% brightness, and you will hear a noticeable click sound when switching on or off.
Technology’s mission is to make our life easier, but it often adds stress and frustration when it doesn’t work as expected.
Here are the solutions to the top problems with Leviton switches. These troubleshooting tips may work with other switches.
- Device not responding in the Home app
- Device stuck on or off and can't operate manually at the wall
- The device turns back on after giving the command to turn off.
- Leviton Switch is connected and shows responding to commands, but it doesn't actually turn on or off the light or fan
- Dimmer is making LED bulbs noisy
Device not responding in the Home app
To fix this problem, I'm assuming you have a reliable
wifi mesh system
installed in your home. Having strong coverage throughout your home will prevent most disconnect problems.
Easy fix
- Make sure you have the latest firmware on the switch by going to the Leviton app.
- Go the physical device and see if its indicator light is flashing, indicating a problem. Push the up button for ONLY 3 seconds to trigger the disconnect and reconnect routine in the switch or dimmer. Let the dimmer scan and go back to green. Most of the time, this will fix the issue (must have the latest firmware)
Medium fix
- If the previous step didn't work, the next easiest step is to cut the power to the device and let it reboot. You will see the lights blink and go through the connection routine.
Super Fix (soft-pair)
- If cutting the power didn't work, the next step is to soft-pair the device.
- To soft-pair, go to the device with iPhone on hand and hold the switch or dimmers up button until the amber light comes on. (About 6 seconds) DO NOT HOLD ANY LONGER OR YOU WILL TRIGGER THE FACTORY RESET
- The light will start to blink fast, indicating pairing mode.
- Go to the settings app on your phone and enter wifi settings
- you will see the "Decora smart device" pop up below the wifi networks. Click to continue
- After successfully connecting, go to the Home app, and you will see your device coming back to life!
- You may need to try a few times. I've had to start soft-pair multiple times with a couple of devices while others pair immediately. If you are experiencing consistent failure to connect, reboot your phone and hold the up button on the device for 6 seconds to restart the soft-pairing routine.
Super Pain Fix (Hard-reset)
- If the above steps didn't work, the last resort is to do a hard reset of the device. You will need to delete the device from your home app, and any scenes or automations will reset.
- To hard-reset, you must hold the up button on the device until the red light starts to blink.
- Once reset, Do the soft-reset routine and then add the device in Homekit by scanning or typing the code.
- Since updating to the latest firmware, the need to hard reset stoped. If you find yourself having to do this, I will check to make sure I have a strong signal going to the device. Sometimes all-metal-gang applications in the wall prevent the wifi signal from reaching the device.
Device stuck on or off and can't operate manually at the wall
the device getting stuck usually happens after a power failure or brownout.
- The only fix is to cut power to the device at the breaker.
- If the device has the latest firmware, let it reconnect automatically
- If it doesn't connect after about a couple of minutes, you can soft-pair.
The device turns back on after giving the command to turn off.
This "weird phenomenon" only occurs to switches. After it happens, the device will start to reset its connection automatically. It doesn't happen often, but I've had these devices for over three years, so I've seen it all.

if you are experiencing this, you will need to contact support at dssupport@leviton.com with a copy or link to your proof of purchase. I've experienced this, and the only fix was to get the device replaced under warranty. The customer support experience was tremendous, and they sent the replacement device right away.
If you are experiencing any other issue, let me know in the comments.
