You’ve just bought a new smart lock from a big-name brand. You install it, download the app, and get ready to unlock your front door from your office... only to find you can’t.
Why? Because the lock only speaks Bluetooth. To control it remotely, you need to buy a separate white plastic box (a "Bridge" or "Hub") for another £50–£90 and plug it into a socket within 3 metres of your door.
It’s the hidden "tax" of the smart lock industry. But it doesn’t have to be this way.
At WME, we believe a smart lock should be smart out of the box. That’s why the WME DL2 and DL1 feature Built-in Wi-Fi. Here is why "No Hub" is the future of home security.
The "Bridge" Trap: How Competitors Catch You Out
Many legacy brands (like Yale’s older models or the standard Nuki) rely on Bluetooth Low Energy (BLE).
- Bluetooth Limitations: It only works when you are standing within 5 - 10 metres of the door.
- The Upsell: To get features like "Remote Unlocking" (letting a tradesperson in while you're at work) or "Voice Control" (Alexa/Google), you must purchase a proprietary Wi-Fi Bridge.
- The Cost: This often adds 30-40% to the total price of your setup. Plus, it takes up a valuable plug socket in your hallway.
The WME Solution: Wi-Fi Built-In
We designed the WME DL2 to connect directly to your home’s 2.4GHz Wi-Fi router. The Wi-Fi chip is integrated inside the lock itself.
Benefit 1: Zero Hidden Costs
When you buy a WME lock, you get everything you need to control your door from anywhere in the world. There is no "Connect Kit" to buy later. The price you see is the price you pay for full functionality.
Benefit 2: One Less Point of Failure
Bridges can be finicky. If someone accidentally unplugs the bridge to plug in a vacuum cleaner, your smart lock goes offline. With Built-in Wi-Fi, there is no middleman. As long as your router is on, your lock is online.
Benefit 3: Instant Remote Access
Because the lock is always connected to the internet via the Tuya Smart Life app:
- Scenario: You are on holiday in Spain. Your neighbour calls to say they need to water your plants.
- Action: You open the WME app and tap "Unlock" (or generate a temporary code).
- Result: The door opens instantly. No range limits.
Bluetooth vs. Wi-Fi Lock: Which is Better?
A common search query we see is "Bluetooth vs Wi-Fi lock". Here is the breakdown:

*Note: Wi-Fi locks do use slightly more power than Bluetooth locks. However, the WME DL2 is engineered with power-saving sleep modes to ensure you still get robust battery life without sacrificing connectivity.
The Power of the Tuya Ecosystem
WME locks run on the Tuya platform. This is a massive advantage over proprietary hubs.
- No "App Clutter": Tuya is a universal smart home standard. You can control your WME Lock, your smart bulbs, your heating, and your cameras all from one app.
- Automation: You can set up "Scenes." For example: "When WME DL2 unlocks (and it's after 6 PM) -> Turn on Hallway Lights." You can't do that easily with a Bluetooth-only lock.
Conclusion: Don’t Buy Half a Smart Lock
In 2026, you shouldn't have to buy dongles and adapters to make your technology work.
If you want a lock that is ready to go, fully connected, and doesn't hog your plug sockets, choose a Wi-Fi Smart Lock like the WME DL2.
