Choosing smart home electronics gets tricky because the products often solve very different problems. A smart plug helps automate appliances, an add-on switch expands a wall-control setup, and a smart door lock changes how entry is managed. The right pick depends less on a single feature count and more on where you want control: at an outlet, at a wall switch, or at a door.
Quick take
- GE Enbrighten Add-On Z-Wave Zigbee Switch White/Almond 12723 Not Standalone is the narrowest but most specific pick: it is for expanding compatible GE-branded in-wall smart-control setups, not replacing a switch by itself.
- Keyless Electronic Entry Door Knob, Keypad Smart Door Knob, Interior D is the simplest lock choice here for shoppers who want a keypad-style door knob with changeable codes and automatic relocking language.
- Security Keyless Smart Door Lock WiFi APP Control Plam Vein 6 Ways Unolck is the feature-heavy lock option, with WiFi app control, palm vein recognition language, video-related features, and several unlock methods.
- Linkind Matter Smart WiFi Plug Home Outlet 6 Pack White Apple Siri Alexa Google is the most outlet-focused choice, especially if you want multiple white smart plugs in one pack for lights, fans, or home appliances.

Concise product notes
GE Enbrighten Add-On Z-Wave Zigbee Switch White/Almond 12723 Not Standalone
This GE Enbrighten add-on switch makes sense when the goal is extending control in a multi-switch setup. The title and description point to Z-Wave, Zigbee, and GE-branded smart-control use, with white and light almond color options and plastic material. Its strongest reason to choose it is specificity: it is designed to mirror functions from a connected GE-branded smart switch, dimmer, or fan control in a multi-location arrangement. The limitation is just as important as the benefit: "Not Standalone" is part of the title, and the description says it cannot be used as a standalone switch. Shoppers wanting one independent smart switch should look elsewhere in this group.
Keyless Electronic Entry Door Knob, Keypad Smart Door Knob, Interior D
This YE LOCK silver keypad door knob is the most conventional entry-control option among the two locks. It centers on keypad use, up to eight changeable codes, anti-spy code encryption wording, a backlit keyboard, automatic locking after opening language, low-power alert language, and a backup battery port. Choose it if you want a smart-style door knob with keypad access rather than a wall plug or add-on switch. Its limitation is that it stays relatively focused: compared with the WiFi app-control palm vein lock, this one does not carry the same title emphasis on app control, video, or multiple biometric-style unlocking methods. It is better framed as a keypad door knob than an all-feature smart-lock hub.
Security Keyless Smart Door Lock WiFi APP Control Plam Vein 6 Ways Unolck
This black smart door lock is the most feature-dense lock in the comparison. The title calls out WiFi app control, palm vein recognition, and six unlocking ways, while the attributes include items such as 150° wide-angle video screen, two-way audio, alarm, anti-peeping password, automatic relocking, doorbell notification, keypad, one-time code, remote control, smartphone compatibility, user management, and video camera. Pick it when those smart-lock controls matter more than a simple keypad knob. The main limitation is condition: it is marked open box, while the other three products are marked new. It also has a long feature set, so it is not the minimalist choice for someone who only wants keypad entry.
Linkind Matter Smart WiFi Plug Home Outlet 6 Pack White Apple Siri Alexa Google
The Linkind Matter smart plug pack is the best fit here for outlet-level automation rather than door or wall-switch projects. The six-pack format is useful if you want several white plugs for electronics, fan control, light control, home appliances, or general outlets. The control styles include app control, digital, push button, and switch, and the features include app-controlled operation, auto-off, remote control, timer, and wall plug-in use. The limitation is ecosystem planning: the description says Matter use with Apple Home, Alexa, Google Home, or SmartThings can require a Matter-certified hub or controller, while AiDot app use is described separately. It is also a plug solution, not a replacement for a built-in switch or lock.
Final recommendation
If you are choosing strictly by job-to-be-done, the cleanest pick for most outlet automation needs is the Linkind Matter Smart WiFi Plug Home Outlet 6 Pack White Apple Siri Alexa Google at USD 33.99 because it covers multiple plug-in devices in one pack and supports app, timer, and remote-control style use. For a smart lock, choose based on how much access technology you want: the Keyless Electronic Entry Door Knob, Keypad Smart Door Knob, Interior D is the keypad-focused door knob at USD 47.79, while the Security Keyless Smart Door Lock WiFi APP Control Plam Vein 6 Ways Unolck at USD 26.99 carries the broadest lock feature list but is marked open box.
The GE Enbrighten Add-On Z-Wave Zigbee Switch White/Almond 12723 Not Standalone is the lowest listed choice at USD 15.91, yet it is also the most specialized. Buy it only for the add-on role described in the title and product language. The 67% spread between the lowest and highest listed prices is less important than matching the category of control: add-on wall control, keypad door entry, feature-heavy smart lock, or multi-outlet smart plug control.
