Choosing smart home electronics gets easier when you separate the job you want done: door access, light dimming, voice/app control, or expanding an existing switch setup. The four items here are not interchangeable, even though they all sit in the smart-home lane. Two are deadbolt-style entry products, one is a wireless dimmer kit, and one is specifically an add-on switch that is not meant to work by itself.
Quick take
- Best for app-connected deadbolt access: Philips Home Access 4000 Deadbolt Bluetooth Smart Keyless Door Lock DDL240X-1HB, because it centers on Bluetooth and keyless entry in a black matte finish.
- Best for keypad-heavy door access: ARPHA Smart Front Door Lock Set 100Code Electronic Keypad Deadbolt Keyless Entry, because it focuses on keypad use, user codes, one-touch locking, and reversible handing.
- Best for adding wireless light dimming: Smart Wireless Dimmer Switch and Receiver Kit, NO Wiring, Work With Alexa, because it combines a receiver, remote-control style operation, app control, and wireless dimming.
- Best for extending a compatible GE smart switch setup: GE Enbrighten Add-On Z-Wave Zigbee Switch White/Almond 12723 Not Standalone, because the title and description make clear it is an add-on rather than a standalone switch.

Concise product notes
Philips Home Access 4000 Deadbolt Bluetooth Smart Keyless Door Lock DDL240X-1HB
This Philips deadbolt is the most entry-focused option for someone who wants a black, matte smart lock with Bluetooth and keyless operation. The universal/reversible handing helps it fit the door-direction question better than a lock with a more specific handing requirement. It also includes hardware and a key, which matters if you want the lock package to cover both smart and physical entry basics. The tradeoff is condition: it is listed as open box, not new. It is also the highest-priced item in this comparison, so it makes the most sense when the door-lock role is the priority.
Smart Wireless Dimmer Switch and Receiver Kit, NO Wiring, Work With Alexa
The Nexete kit is the lighting-control pick for shoppers who want a wireless dimmer and receiver rather than a door device. It stands out for app control, remote control, wireless operation, and the included CR2032 battery. The description also emphasizes brightness adjustment, a wall plate, and use with Alexa, so it is aimed at people trying to control lighting more flexibly. Its limitation is focus: it is not a general smart-home hub, door lock, or standalone wall-switch replacement in the same sense as a hardwired smart switch. It is best judged as a light-control kit.
ARPHA Smart Front Door Lock Set 100Code Electronic Keypad Deadbolt Keyless Entry
ARPHA is the keypad-centered door option. It is new, silver, matte, and universal/reversible, with features that include 100 user codes, anti-peeping password, automatic relocking, one-touch lock, keypad, keyless use, and included keys. That makes it appealing if you want a front-door lock set with multiple entry-code management features instead of a lighting product. The limitation is that its description includes a long mix of lock functions, so shoppers who mainly want Bluetooth in the product title may prefer the Philips model. Its silver finish also may not suit a door where black hardware is the goal.
GE Enbrighten Add-On Z-Wave Zigbee Switch White/Almond 12723 Not Standalone
The GE Enbrighten switch is the most specific item here: an add-on Z-Wave/Zigbee switch in white and light almond. It is meant for shoppers expanding control points for a compatible GE-branded smart control setup, and the description highlights multi-switch operation from additional locations. Choose it when the phrase "add-on" is exactly what you need. The limitation is equally important: the title says "Not Standalone," and the description repeats that it cannot be used as a standalone switch. If you need a complete independent light-control kit, the Nexete dimmer kit is the more direct match.
Final recommendation
Start with the device category before comparing finishes or smart features. If you need a door lock with Bluetooth, the Philips Home Access 4000 Deadbolt Bluetooth Smart Keyless Door Lock DDL240X-1HB is the clearest match, though its USD 36.56 price is the top of the group and its condition is open box. If you want a new keypad deadbolt with many code-oriented features, the ARPHA Smart Front Door Lock Set 100Code Electronic Keypad Deadbolt Keyless Entry is the more focused pick at USD 22.49.
For lighting, the choice is between a complete control kit and an add-on part. The Smart Wireless Dimmer Switch and Receiver Kit, NO Wiring, Work With Alexa is the better fit when you want wireless dimming with app and remote control. The GE Enbrighten Add-On Z-Wave Zigbee Switch White/Almond 12723 Not Standalone is the right call only when you specifically need an add-on switch for a GE Z-Wave or Zigbee-style multi-switch setup. Overall, the best practical choice is the one that matches the job: Philips or ARPHA for entry, Nexete for wireless dimming, and GE for an add-on switch role.
