The quick explanation
💡
Smart Bulb
Replace your regular bulb with a smart one. The intelligence is inside the bulb. No wiring, no tools — just screw it in.
🔘
Smart Switch
Replace the wall switch. The switch becomes smart and controls any normal bulb. Requires opening the wall box.
📦
Smart Module
A tiny box hidden behind your existing switch. Your switch looks the same — the module handles all the smart logic invisibly.

💡 Tip
You can combine approaches: smart bulbs in bedside lamps + a module behind the hallway switch. Most homes end up with a mix.
For 90% of people, this is the answer.
Smart Bulbs
Zero wiring, zero tools, works in 5 minutes — and you can take them with you when you move.
See top bulb picks →⚠ Avoid these mistakes
- 1
Turning off the wall switch after installing smart bulbs
Smart bulbs need constant power. If someone flips the switch off, all your automations break. Use a dummy-switch cover or a button scene controller instead.
- 2
Buying a smart switch without checking for a neutral wire first
Most smart switches need a neutral wire in the wall box. Check before you buy — not all older homes have one. Some brands offer no-neutral models.
- 3
Mixing Zigbee, Z-Wave, and Wi-Fi devices without a hub
Each protocol is a separate world. Without a hub like Home Assistant, your devices won't talk to each other. Pick one protocol and stick to it — or get a hub first.
- 4
Buying a full Hue starter kit when you only need 2 bulbs
The Hue Bridge is only worth it at 5+ bulbs. For 1–3 bulbs, Wi-Fi or standalone Zigbee options cost half the price and work just as well.
⚠️ Common mistake
Never turn off the wall switch once smart bulbs are installed — you'll lose all automations instantly.

Frequently asked questions
Do I need a hub to use smart bulbs?
It depends on the brand. Philips Hue requires its own bridge. IKEA TRADFRI has its own gateway. Wi-Fi bulbs (like TP-Link Tapo or Shelly) connect directly to your router — no hub needed.
Can I still use my physical wall switch with smart bulbs?
Technically yes, but you shouldn't turn it off. The switch cuts power to the bulb, which kills all automations. Replace it with a smart button or a dummy-switch cover that stays on permanently.
What's easier to install — a bulb, a switch, or a module?
Bulb is always easiest: screw in, done. Modules and switches both require opening a wall box. Both may need an electrician if you're not confident.
Can I mix brands?
Yes, as long as they use the same protocol. All Zigbee devices work together on the same hub. Wi-Fi devices usually need their own app but can be unified via Home Assistant.
Which option has the best value for money?
For most homes: smart bulbs in lamps and bedrooms (no wiring), modules in hallways and kitchens (no bulb change). This hybrid approach gives 80% of the smart-home experience for the lowest total cost.
