Controlling smart home accessories through the Home app or voice with Siri is absolutely magical, but this magic can quickly turn into frustration if your accessory suddenly drops with a dreaded case No answer error. No answer status not only means you lose the ability to control your accessories, but it also affects automation and scenes, which can really disrupt a home.

Because HomeKit is based on a variety of factors and involves multiple devices, aiming for an exact fix for No answer the problem can be a little complicated. Sometimes it's a spotty wireless connection; the next day, it might just be an issue with the Home app that needs a restart. With a little patience, you can bring that accessory back to life, you just have to follow the steps below to get started.

First things first

Before we delve into the deep stuff, there are a few simple settings that you should check on your iOS device. These include ensuring that your device is connected to your home Wi-Fi network and checking that Bluetooth is active.

Next, make sure your iPhone is signed in to your iCloud account. You can do this by accessing the Settings app and checking if your name is listed at the top. Otherwise, see our login guide below.

Lastly, make sure you're running the latest version of iOS or macOS, as well as on the HomeKit hub, such as Apple TV or HomePod. For more details on the update, see the guides below.

Narrows it

Sometimes a HomeKit accessory can look No answer message, even if it is actually connected to the home network. To narrow it down to an accessory issue or a launcher issue, you can check if the app is accessible to your device to see if you can control it from there. If you can, then you can turn your attention to HomeKit troubleshooting.

If your accessory is available in another application, you can check for firmware updates that may resolve the issue or refer to the specific HomeKit steps provided by the manufacturer.

At home or away

If your HomeKit accessory is only displayed No answer when you're not at home, then you may need a HomeKit hub. HomeKit centers bridge the distance between the accessory and the internet, allowing you to access your equipment while you're out and about at the same time, allowing you to create automations.

There are currently three types of HomeKit hubs that are available: Apple TV (4th generation or later), HomePod, and iPad (running the latest version of iOS). HomeKit hubs, even on hold, will handle all connections in the background and are generally automatically activated when you sign in to your iCloud account during the device setup process.

If you already have one of these devices in your home, you can check the status of the HomeKit in the Home app on iOS. An active HomeKit hub will be displayed as Logged in in the Home app and if you have other hubs in the house, they will appear as Standby. If your hub is not displayed Logged in or it is not displayed at all, then you will need to activate it on that device. Here are the steps to check the status of your hub.

Restart all things

As with most problems, sometimes a simple restart is all it takes to make things work. Resolving the HomeKit issue, restarting the HomeKit hub, the iOS device, and even the accessory itself is one of the fastest and easiest ways to make the accessory unanswered again.

How to restart or reset iPhone and iPad

Recharging a HomeKit accessory usually only requires disconnecting it from the wall or removing the batteries. In some cases, you can also use the associated application if it is connected to the home network and can be seen by the application.

Restarting an Apple TV requires either disconnecting it, using the menus on the device, or using a combination of buttons on the Siri remote.

For HomePod, you can simply unplug it or use the Home app. Restarting it through the Home app can be a little dangerous, although you'll be presented with options to restart or reset your HomePod, so be sure to pay attention before you touch it. Here's how:

1. Launch The home app.
2. touch rooms.

3. Swipe left or right to locate The room that your HomePod is inside, then tap and hold the button HomePod.

4. Click on Settings icon.
5. Swipe down and tap Reset HomePod

6. touch Restart the HomePod.

   • Make sure you tap the restart option. If you tap Remove accessory, your HomePod will be reset to factory settings.
   • Restarting the HomePod will take a while and will not be available for voice commands during this time
   • If your HomePod is the homeKit hub in your home, you'll temporarily lose access to accessories

Traveling the distance

The vast majority of HomeKit accessories on the market use wireless radios to communicate with your home network. Common wireless types are Wi-Fi, Bluetooth, ZigBee and RF, all of which are limited in their maximum range. If you have only one accessory that comes and goes, then you may be a victim of a spotty signal.

Solving the problem can be as simple as moving the accessory to another location or moving the HomeKit hub. There are several different tools you can use to help diagnose an accessory connection, most of them.

For Wi-Fi connections, check the application or web portal you use to manage your router. Most modern routers will display signal strength as an easy-to-read icon or as a description Excellent. Some routers will display power in numeric form, such as -50 dBm, and the smaller the number, the better your signal. If your signal is at or above 70 dBm, then you may experience connection problems.

If your signal isn't strong and you can't move your accessories, hub, or router, then you might want to look into a Wi-Fi networked router, such as the popular eero line. These routers have multiple access points spread throughout the house to extend the range and also support HomeKit Secure Router functions

For Bluetooth accessories, the signal strength can also be checked, but to do this you will more than likely need a third-party HomeKit application. We recommend the HomeScan app for HomeKit, as it is adapted for HomeKit and comes with a handy Apple Watch app that makes diagnosing a connection even easier.

The HomeScan application will display power in numerical form, as with Wi-Fi connections, a signal around -70 dBm or above can cause inconsistent performance. If you have a HomeKit hub in your home, you will need to make sure that you measure the power relative to where your HomeKit hub is located. You can do this by setting your iPhone on or near your Apple TV, iPad, or HomePod, and then using the Apple Watch while sitting next to your HomeKit accessory.

The ZigBee and RF accessories communicate to a dedicated hub and, as such, the signal strength, if available, will be reported via the accompanying application. The most popular brand that uses ZigBee is Philips Hue, which uses it for its line of light bulbs and lamps, and for RF, the Cassette Lutron line is one of the best known.

In most cases, these types of accessories use a form of mesh that extends the coverage in the house, allowing the accessories to connect to each other. However, these radios are generally low power, which means that they have a shorter range and are affected by walls and materials inside the home. If you can't move your accessories or dedicated hub, then adding a brand-specific range extender or even another accessory can help. You can also try to change the hub channel that works if the manufacturer's application supports it.

The nuclear option

If all else fails, resetting the HomeKit or HomeKit accessory may be the only solution. When you reset an accessory, it will return to its original settings, removing it from the HomeKit and home network. This process varies, but common methods include holding a button on the device for a few seconds or removing it from the manufacturer's application. Once it is reset, you will need to add it back to your network following the same process as before to connect it.

How to configure HomeKit accessories

Resetting your HomeKit at home should be the last step you try, as it will not only remove problematic accessories, but will remove all accessories, scenes and automations. Because there is no backup and restore process provided by the Home app, this option means you'll have to reconfigure everything from scratch, so it's time consuming. There are several third-party applications, such as the HomeKit Controller, that can back up scenes and automation, but will not restore real accessories.

As with HomeKit cameras, HomeKit lighting has gained significant momentum in the last two months, with the introduction of two new light panel systems. Although the colorful, decorative HomeKit lighting is certainly not new, the shapes of the latest offerings are: hexagons. For whatever reason, the hexagonal lights activated for HomeKit were not simply a thing for the first years of the platform's life, but now, all of a sudden, we have two.

First of all, it was the Nanoleaf Shapes series of panels, which I thought was an excellent entry into the product line for their ease of installation, sensitivity to touch and well, just as nice looking. The next thing is LifeSmart Cololight Plus, which I've been testing in my house for the past few weeks. Even though they have a similar shape, Cololight Plus and Nanoleaf Shape vary drastically in several key areas: price and capabilities. With Cololight Plus coming with kits starting at up to $ 25, we'd expect it to offer a lower-end setup, application, and lighting experience, but surprisingly, that wasn't the case at all.

Tons of color

LifeSmart Cololight Plus: features

LifeSmart’s Cololight Plus comes in a variety of starter kits, the most affordable edition consisting of a single panel and the important controller, with which I started testing the system. The regulator acts as a base for the panels, with all the smart elements filled inside the tiny white frame and attaches to each hexagon through a small detachable connector. The base has a single button on the front, which acts as a power switch and as a way to scroll through a series of pre-programmed scenes.

Around each side of the button are a few small holes, one of which is a microphone that allows the system to react to music or noise in a room, and the other hides a reset button inside. At the back is a detachable USB-A power cable that can handle up to 10 panels, although additional power sources can be used for further expansion, reaching up to 255 panels in total. Although a USB connection powers the Cololight Plus, unfortunately, LifeSmart does not include an electric brick in the box.

The actual light panels themselves are quite small, measuring 3.4 "x 2.9" x 1.2 "and weigh only 0.12 lbs each. The panels are constructed of a mixture of plastics, with the front having a slightly frozen appearance but hiding Internal LEDs Inside: Inside the panels are a series of 19 LEDs that give Cololight Plus the ability to display multiple colors on a single light.The panels support the industry standard of displaying 16 million different colors and shades white, along with darkening functionality.

On the back of the panels is a set of six ports for the connector parts on each side of the hex and one that includes an additional connector that supplies power from a base unit. The panels can be wall mounted with a separate plastic part that attaches to the back of the panels, but is not included in the starter kit or additional panels. The additional wall panels are sold in simple packaging, as well as in three and six packages, giving owners an affordable way to expand as needed, which I did after setting up the original package.

Connecting Cololight Plus to a home network takes place via 2.4 gHz Wi-Fi, without the need for a dedicated hub. Cololight Plus works with the Cololight app, available for free in the iOS and Android App Store via Google Play. In-app controls include the ability to go through scenes, set solid colors, and switch power. Custom scenes can be created by the app, with handy presets available, which display various animations or movements that the panels are capable of, and the scenes can include different speeds and, of course, colors.

In addition to the Cololight app, the system works with all major smart home platforms: Alexa, HomeKit and Google Assistant. For Apple HomeKit users, the panels can be configured entirely through the Home app, bypassing the need for an app entirely if you wish. The Cololight app also includes a guest mode, which allows HomeKit users to access firmware updates, adjust scenes, and even create scenes, all without registering for an account. However, for those on Android, registration is required for smart controls and remote access.

Sweet scenes

LifeSmart Cololight Plus: What I like

Since Cololight Plus is HomeKit enabled, setting it up was an easy breeze. Once disconnected and connected, all it took to connect is a scan of the HomeKit association code. Of course, the direct association with HomeKit limits you to the standard color options shown in the Home app, but is immediately available for use in automation with other accessories and scenes. Even though it is limited in this state, I love the way Cololight includes several different built-in light scenes, which can be accessed by pressing the button in front of the base, which makes the whole package easily accessible to almost everyone.

Speaking of light scenes, the ones included right out of the box are fantastic. Combined with the inclusion of several LEDs inside each panel, certain light scenes are truly dynamic, with effects such as breathing and swirls, which incorporate different shades throughout the surface. I especially like it Instashare scene, which moves quite quickly pastel colors from the bottom of the panel to the top. The effect is amazing to see in person and is my goto scene when I'm at my office. The color reproduction was good, although, as with all light panels, it struggles with certain colors such as green or red, but it ends.

I especially like the Instashare scene, which moves the pastel colors from the bottom of the panel to the top pretty quickly, which is amazing to see in person and is my goto scene when I'm at my desk.

As mentioned, the colors and scenes use the front of the entire light panel, thanks to an almost invisible light at the edges. Unlike the hexagons recently launched by Nanoleaf, which have visible spaces in each corner and in each of the panels, the gap on the Cololight panels is extremely small, giving it a more perfect look. Cololight panels also produce uniform lighting, even in the corners, another area where the most expensive Nanoleaf shapes struggle. To be fair, Nanoleaf's lights are touch sensitive and slightly two to three times thinner (and larger) than LifeSmart panels, but it's still impressive to see in a device that starts at a low price.

Sticking to the design, I like the modular nature of the Cololight Plus and how you can buy as little as possible a panel with a controller to get things started. For testing, I started with a single set of panels and then purchased a few additional panels to get a better sense of how they connect. Connecting each additional panel is super simple, and the connector parts are rigid and solid. Each connector clicks satisfactorily when set in place, and because of their thickness, I had no fear of breaking when expanding or making changes.

Light application, light base

LifeSmart Cololight Plus: What I do not like

While I like that Cololight Plus can work on a flat surface with its base included, there are a few tiny aspects that generate the experience on the table. Despite the lightness of the panels, the base will shrink if your design is not evenly distributed. For example, if you start with one panel at the base, then add another to the left or right, it will tilt in that direction. Sure, you could attach the base to the surface if you really wanted to with some sort of mounting tape, but it would have been nice to see a suction pad on the bottom or just extra weight inside.

Also, the base is not as sleek as the regulators on the Nanoleaf shapes mentioned above and will no doubt look a little weird if mounted on the wall. Wall mounting itself is another problem, as the proper hardware is not included in the box and I could not find a place to buy the necessary parts. With the ease of the panels, I could see that the tape is a viable option for wall mounting, but I would prefer a more permanent solution if I put it on the wall. That being said, however, I intend to use Cololight panels strictly as a desk light, as they seem to me to be a little too thick.

The Cololight app, like most device manufacturer apps, isn't exactly great. Navigating the application is frustrating with unmarked buttons and inconsistent response times. Just finding the option to set custom colors or patterns was difficult because it was buried in the same screen that acts as a quick menu to jump between scenes. Changing scenes through the Cololight app was hit or failed, some cases took effect instantly, and others never applied, showing instead a message that the light was not responding. Simply making the change again would solve the problem, but the inconsistency was annoying.

Light control through HomeKit and the Home app has provided a familiar rescue, but again, it's very limited. Through the Home app, Cololight is presented as a single accessory, no matter how many panels you have. Any change in color or brightness you make will apply to the entire set of panels, which means, of course, that you'll need to use the Cololight app for anything but simple adjustments. I found that setting a scene or color through the Home app worked every time, so I'm not really sure why the Cololight app fought.

Cheap, connected and colorful

LifeSmart Cololight Plus: Bottom line

4
of 5

Despite its smaller size and lower prices, LifeSmart Cololight Plus is a great alternative to Nanoleaf's popular smart lighting line. With kits starting at just $ 25, the LifeSmart offer is great for those who have always wanted to try a light panel set up, but didn't want to commit. The modular nature of the panels offers the option to expand as needed, and the included base allows them to go where Nanoleaf panels cannot: on the table, desk or shelf.

Certainly, the Cololight app is unpleasant and not as receptive as it should be, but Cololight Plus compensates with a really extremely edge design and more LEDs on the panel. Multiple LEDs make the scenes come to life with amazing effects and give the whole panel even lighting, even in the corners. Combined with support for all major home platforms and voice assistants, HomeKit included, LifeSmart Cololight Plus is a fantastic value and a great way to add a little color to almost any room.
