With or without a hub: which suits me?
Without a hub is the easiest start: screw in the bulb, connect it to your Wi-Fi or phone, done. That suits you if you want to make one or two lamps smart first. With a hub you pay more at the start, but you get the most features and lots of accessories, for example switches and motion sensors. That is worth it above all if you want to equip several rooms. With Philips Hue you can also start without a Bridge and add it later.
Does Philips Hue work without a Bridge?
Yes, by Bluetooth. Then you control up to ten bulbs directly with your phone, according to the manufacturer about ten metres away. That doesn't work when you are out, and you can only use schedules, routines and accessories to a limited extent. Most Hue bulbs work both ways. So you can add the Bridge at any time and keep your bulbs.
Bridge or Bridge Pro?
The normal Bridge controls up to 50 bulbs and 12 accessories such as switches, and it is connected to your router by cable. According to the manufacturer the Bridge Pro handles more than 150 bulbs and 50 accessories, it also connects by Wi-Fi, and only with it do you get MotionAware. If you don't need MotionAware, the normal Bridge is enough to start with, as in the Essential set.
What is MotionAware?
It turns your Hue bulbs themselves into a motion sensor. When someone moves in the room, the radio signals between the bulbs change, and the light comes on. You need the Bridge Pro and at least three Hue bulbs in the same room, but no extra motion sensor. According to the manufacturer almost all Hue bulbs take part, only some older models don't. MotionAware costs nothing extra for your light, only for alerts to your phone Hue charges a subscription. Walls between the bulbs can interfere. And so that your pet doesn't switch on the light, you set MotionAware to be less sensitive in the app.
Do smart bulbs use electricity when they are off?
Yes, a little, because they wait for your commands. In the EU a smart bulb may use at most 0.5 watts for this since September 2021. That is a good 4 kilowatt hours a year, at 37 cents per kilowatt hour, the average in Germany, so around €1.60 per bulb. According to the manufacturer the bulbs in the Hue set with Bridge Pro only need 0.1 watts for this, the cheaper Hue Essential 0.5 watts. For a lamp that is hardly ever on, for example in the storeroom, you are better off with a normal LED bulb.
What happens if I switch off the normal light switch?
Then the bulb has no power and no longer reacts to the app, schedule or voice. So leave the switch on and switch with the app or a smart switch. You simply stick the Hue switch on the wall, for example right next to the old one. There are also modules that go behind the normal light switch. But for those you work on the mains wiring, so if in doubt leave it to an electrician.
What happens if the internet goes down?
According to the manufacturer, with the Hue Bridge you can control your light even without the internet. In the Stiftung Warentest test, however, the Wi-Fi bulbs only reacted with a delay when the internet was down. And your normal light switch keeps working in any case.
Will they fit my lamps?
Look at the cap of your old bulb. Most lamps have the large E27 screw cap, and the bulbs here are for that. Hue and WiZ also come for the small E14 cap and for GU10 spots, then check the cap in the name when you buy. In the UK many lamps use the B22 bayonet cap. Hue and WiZ also sell B22 versions, so check the cap in the name.
And in Austria and Switzerland?
In Austria everything is the same as in Germany. In Switzerland the bulbs fit just the same, E27, E14 and GU10 are the same caps. You can also get Philips Hue and WiZ from Swiss retailers. If you order in Germany, look at the plug of the Bridge's power supply: a flat Europlug with two thin pins also fits Swiss sockets, a thick Schuko plug does not.
How did you choose the bulbs?
I have been using Philips Hue myself for about ten years. For the selection I read the test by Stiftung Warentest, Germany's best-known consumer tester (issue 2/2024, ten bulbs). Only two were good there: Philips Hue with Bridge as test winner and WiZ as the best bulb without a hub. Because the test is almost three years old, I also read newer tests from the tech sites nextpit, TechRadar and PCWorld, for example on Hue Essential and MotionAware, and compared the manufacturers' details. I couldn't find the new IKEA bulbs on Amazon, you can get them at IKEA itself.
