It would seem that we’ve waited a long time for Signify to present their first smart plug* that works with the Philips Hue system, but it’s finally here. Immediately after the official release, I was able to buy one at a local store. The Philips Hue System itself sets the bar high from the beginning, so let’s see how it fares with this newest smart plug.

* This isn’t actually Philips first smart plug per se, but it is the first ‘Philip Hue’ branded Smart Plug. There are a couple of pics further down showing early products.

PACKAGING

The packaging doesn’t significantly differ from what we typically see with other products from the Philips Hue series, except for the addition of the Bluetooth logo, which is beginning to appear on the latest and updated products. Inside, in addition to Hue smart plug, there’s a quick set up manual in several languages along with a simplified EU declaration of conformity document.

THE PLUG

From the first moment, you can see that the Hue Smart Plug is made with attention to detail, with the use of high-quality materials, but then we didn’t expect anything less. The design is clear and simple. On the smart plug itself, there’s one button with which you can turn it on or off in addition to a single LED showing the power status of the device, as well as other states – like network connection status for example.

Basic specifications:

supply voltage 220-240V

rated load current 10A

maximum power 2300W

dimensions 51 x 51 x 83.5 mm

INSTALLATION

The Hue Smart Plug can work as a totally independent Bluetooth device or as a Zigbee device. If you want to use the plug’s ZigBee capabilities, you must have a second generation Hue Bridge. Depending on which option you opt for, there are two applications available for iOS or Android. The Philips Hue Bluetooth app or the Philips Hue app. This is due to the difference in functionality depending on the protocol used. It should also be noted that the Hue Smart Plug cannot be used simultaneously via Bluetooth and Zigbee.

There is also a third option explained in the quick setup manual where you can pair the Hue Smart Plug directly with a Hue Dimmer switch without the need of either of the app or a Hue Bridge. Direct linking between two devices is one of the advantages when using the ZigBee protocol. Whilst the Hue dimmer Switch can be used directly with the Hue Smart Plug, this does not allow for any kind of dimming control however. So, if you were hoping that you could place a ‘dumb’ but dimmable LED bulb into your lamp, and then have that plugged into the smart plug, for the purposes of dimming said bulb with the dimmer, it’s ‘no dice’ I’m afraid. You can only turn the plug on or off, which essentially renders the dimming up and down buttons non-functioning with regards to the plug.

Regardless of the connection method and application used, the setup is very simple and you only need to follow the instructions presented in the application. There is an additional instance when configuring the Hue Smart Plug via Bluetooth, where a query from the system wants to know whether we want to allow the device connection with the phone via Bluetooth. After successfully adding the device to the system, we only have access to two configuration settings; Assigning it to a given room, and how it should behave after a temporary power failure. You can choose between two options there;

Default – Turn on Power loss recovery – Last used on or off state.

Using The Hue smart plug in an everyday scenario, the first thing we notice is the very quick response to commands whether using Bluetooth or ZigBee. The difference between them is almost imperceptible. After a few days of using the device, there wasn’t a single instance where the Hue Smart Plug did not respond to a command or responded slowly. However, there may be different results when using the Smart Plug through integrations with other systems beside Philips Hue. It is also worth noting the differences in functionality depending on the use of this smart plug via Bluetooth or Zigbee; The primary and only function of The Hue Smart Plug is turning the power on and off, which is how it works via Bluetooth. By connecting it to the Hue bridge, you will gain additional functionality, such as the ability to set various automations triggered by other devices from the Hue family, such as the Hue Tap, Hue Dimmer Switch, Hue Motion Sensor, any Friends of Hue switches, or the latest just announced Hue Button which we are looking forward to. It is also possible, where using geo-location, that it can be turned on or off when we arrive or leave the house. In addition, you can program the timer to enable or disable the Hue Smart Plug at a given time, which is where we encountered our first problem.

For reasons unknown, Signify advertises this product as being used exclusively with lamps. This is reflected in the fact that in the application it is recognised as a regular light bulb and not as an additional device, such as a switch or plug. In essence, this means that it is impossible (in the Hue app) to set an automation exclusively for the Hue Smart Plug, if it is added to rooms with other Hue lights because the automation applies to the rooms and all lights in that room, not individual lights and as the plug is seen as a light, it gets lumped with the other ‘actual’ lights. The only way to circumvent this limitation is to create a separate room for it. This method for The Hue smart plug is more incomprehensible due to the fact that in the technical specifications it is rated for a maximum power of 2300W and 10A load which is the average value for most other smart plugs, and it is hard to find lighting in the home with such a load. I hope that in the future this will change and it will be treated more like a smart plug which will not prevent you from using it for lighting anyway if you want it.

On the packaging, unfortunately, we don’t see any information about integration with other systems, and with what systems we can use this smart plug, but as you can probably guess, the Hue Smart Plug works with HomeKit out of the box, after adding it to the Hue bridge. As it’s like all other Hue products, there’s no HomeKit code as such, as it’s not required, because it’s the Hue bridge that is responsible for exposing this plug to HomeKit. Once added to the Bridge, it shows up in HomeKit just like any other smart plug/switch. Each of the available integrations with smart home systems requires the use of the Hue Bridge because the Bluetooth connection is only local between the device and the phone and does not allow any connection with other systems. The Hue bridge system works with many integrations, which I won’t mention all here. The most popular of these, besides HomeKit, are Google Home, Amazon Alexa and IFTTT. Unfortunately, I couldn’t test all these integrations at the time of writing, but the Hue smart plug should work with most of them. As soon we can test it with other systems then we will update the article.

ORIGINAL PHILIPS SMART PLUG

Philips did actually make smart plugs way back in 2012, that did, in fact, work with the original round Hue Bridge. These smart plugs do look a lot like the current Tradfri smart plugs by Ikea.

SUMMARY

In general, it is a very good, high-quality smart plug. The use of Bluetooth is certainly the easiest way to improve the operation of lights in your home, without investing in additional devices (like the Hue Bridge) whilst at the same time providing a good way for Signify to acquire new users, with a high probability that sooner or later they will invest in the Hue Bridge and other Philips Hue devices.

For those users who already have a Hue bridge, this smart plug offers many additional functions. Automation and integrations with more devices from the Philips Hue series, Remote access when you are away from home and additional integration with other systems, and there are really many of them. As a bonus, the Hue system has probably the largest choice of third party application. The tight integration with the Philips Hue system, along with all Hue devices working together with renowned reliability, is definitely a big pro for this smart plug, and I think that the price is also reasonable for this kind of device.

Unfortunately, the size of this smart plug definitely has to be a negative point. In this regard, it belongs to the category of larger smart plugs, like the current Eve Smart plug. The version we tested is the European version and it blocks two sockets in every double-wall outlet or when used in a power strip. Most other smart plugs are not much smaller, so it’s time for manufacturers to start thinking about this issue. Adding a smart plug that occupies two outlets doesn’t seem to be the smartest solution, which is slowly being overcome with North American smart plugs like the Vocolinc SmartBar, and the Satechi Dual Smart Outlet, for example.

The one really useful missing feature is power metering. Designating it in Philips Hue app as a standard light bulb is just as strange, and limits some potential additional functionality. My first thoughts in this case that comes to my mind are whether it is better to buy a Hue smart bulb instead of the Hue Smart Plug, where for a lower price we will get exactly the same functionality, with it being a totally transparent solution in regards to what type of device it is. These bulbs are even sometimes part of a starter pack that includes a Hue Dimmer, so along with not blocking 2 outlets or having a large ‘brick’ of plastic sticking out from the wall, it becomes more confusing as to why they’ve gone down this road. I hope this is just an incomprehensible advertisement from Signify, and fortunately for those who want something like this, we can still use it as a regular smart plug in HomeKit, bearing in mind to not go beyond 2300W max power rating.
