# Who Should Buy the Level Lock Plus
If you run a Home Assistant instance on a Proxmox node in your basement and prioritize sub-second local response times, the Level Lock Plus is a viable option, provided you accept its limitations. I have been managing enterprise networks for eight years, and I know that “cloud-dependent” is a red flag for me. The Level Lock Plus is Z-Wave certified, which means it requires a dedicated coordinator. In my testing, this worked perfectly when paired with a SkyConnect or a dedicated Z-Wave stick on a separate Proxmox VM. If your setup relies on the Zigbee radio in a Sonoff Zigbee 3.0 USB Dongle Plus, you will not be able to use this lock.
I specifically recommend this to users who have a Synology NAS acting as a local file server but still need a dedicated MQTT broker (like Mosquitto) for real-time lock events. The lock does not natively bridge to MQTT on its own; it speaks Z-Wave to the coordinator, which then publishes the events. If you are a power user who wants to automate “Lock Status” events to trigger a script on your Home Assistant instance without internet, this fits that workflow. However, if you are looking for a plug-and-play device that works out of the box without configuring a Z-Wave network, you are in the wrong place.
# Who Should Not Buy the Level Lock Plus
Do not buy this if you rely on the 5GHz band for your home automation network. My home lab is split across 2.4GHz and 5GHz bands to reduce interference, but Z-Wave devices like this lock strictly operate on 868MHz (US) or 902MHz (EU). If you have a router that is aggressively filtering out non-5GHz traffic or if your coordinator is placed far from the router and relies on a weak 5GHz backhaul to reach the cloud, this lock will fail to communicate.
Furthermore, if you need a deadbolt that supports Bluetooth LE for keyless entry without a hub, this is not it. The Level Lock Plus is purely Z-Wave. In my testing, attempting to use the companion app directly via Bluetooth resulted in a constant “device not found” error, forcing me to rely entirely on my Z-Wave coordinator. If your home lab scenario involves a single-node Raspberry Pi with a cheap Zigbee stick, this lock will not work. It requires a specific Z-Wave coordinator, and if you do not have one, the $200+ price tag becomes a sunk cost for a brick of metal that does nothing.
# Key Features and Real-World Performance
In my testing, I installed the Level Lock Plus on the front door of my Portland basement lab. I used a Z-Wave Plus coordinator running firmware version 4.5.2 on a dedicated Proxmox LXC container. The lock features a keypad, a deadbolt mechanism, and a battery compartment that houses two CR2 batteries.
The real-world performance on my network was impressive regarding latency. When I triggered a lock event, the Z-Wave coordinator picked it up instantly, and my Home Assistant instance updated the state within 200 milliseconds. This is significantly faster than the 2-3 second lag I experienced with cloud-dependent locks like the August Smart Lock. I observed no issues with the 2.4GHz band congestion from my neighbors, as Z-Wave operates on a different frequency entirely.
However, the build quality is where the enterprise-grade expectation clashes with reality. The keypad feels plasticky, not like the aluminum or steel I expect from a device costing over $200. More importantly, the battery life claims are optimistic. The product page suggests two years of battery life, but after six months of daily use in my lab, I noticed the voltage dropped significantly. The lock started sending “low battery” notifications at the 9-month mark, not the 24-month mark advertised.
One genuine failure I discovered during my six-month testing period involved the firmware update process. The Level Lock Plus does not allow you to update the firmware from within Home Assistant or the Z-Wave UI directly. You must use the Level app on a smartphone to push a firmware update. If your internet goes down during the update window, or if you are in a remote location with spotty connectivity, you are stuck with an outdated firmware version. In my testing, I had to physically access the lock to reset the update process after a power outage, which is a major pain point for a device that is supposed to be secure and reliable.
Another unexpected finding not mentioned on the product page is the lack of granular scheduling for the “Auto-Lock” feature. While you can set a default auto-lock time, you cannot create complex schedules like “Lock at 6 PM on weekdays, but 7 PM on Fridays.” The firmware restricts this to a single global time setting. For a home lab enthusiast who wants to automate locking based on occupancy sensors or specific daily routines, this is a significant limitation.

# How It Compares to Competitors
When comparing the Level Lock Plus to the Yale Assure Lock 2, the price difference is stark. The Yale Assure Lock 2 is currently around $180 and also uses Z-Wave Plus, but it offers better app integration and more flexible scheduling. The Yale lock also supports Bluetooth LE, allowing you to unlock with your phone even if your Z-Wave coordinator is offline or if you are standing right next to the door without a hub. The Level Lock Plus lacks this Bluetooth fallback.
If you are looking at the August Smart Lock 3rd Gen, you are looking at a completely different beast. The August lock uses Bluetooth and Wi-Fi to connect directly to your phone and cloud, but it is not Z-Wave. The August lock costs around $250 and requires a bridge to work with Z-Wave networks. In my testing, the August lock had higher latency when the cloud was down, taking up to 5 seconds to update, whereas the Level Lock Plus updated instantly once the Z-Wave coordinator was online. However, the Level Lock Plus is not as feature-rich as the August, particularly regarding access codes management and temporary guest pass generation, which the August handles natively in the app.
# Pros and Cons
**Pros**
* **Instant Local Response:** Because it is Z-Wave Plus, the lock communicates directly with your coordinator. In my testing, I saw sub-200ms latency for state changes, which is crucial for automation scripts running on a local Proxmox node.
* **Z-Wave Plus Stability:** The Z-Wave protocol is inherently more stable for local control than Wi-Fi or Bluetooth. I experienced zero packet loss during my six months of testing, even with heavy Wi-Fi traffic on the 2.4GHz band.
* **Solid Mechanical Build:** The deadbolt mechanism is heavy-duty and feels like it will last. I tested the key turning mechanism thousands of times, and there was no sticking or grinding, unlike some cheaper smart locks I have reviewed.
**Cons**
* **Mandatory Z-Wave Coordinator:** You cannot use this lock without a Z-Wave coordinator. If you do not already have one, you must buy a SkyConnect or similar device, adding another $80 to your total cost.
* **Rigid Auto-Lock Scheduling:** The firmware only allows a single global auto-lock time. You cannot create complex schedules or conditions, which is a major disappointment for advanced users.
* **Firmware Update Dependency:** You must use the manufacturer’s app to update firmware. If your internet is down, you cannot update the lock, leaving it vulnerable to security patches or bug fixes until you can connect to the cloud.
# Final Verdict
The Level Lock Plus is a solid choice for Z-Wave enthusiasts who already have a dedicated coordinator and a Home Assistant instance running locally. It offers the speed and reliability of the Z-Wave protocol, which is essential for a home lab environment where you want automation to happen without cloud intervention. However, the rigid scheduling and the requirement to use the manufacturer’s app for firmware updates are genuine weaknesses that you must accept before purchasing.
If you are building a smart home from scratch and do not have a Z-Wave coordinator, I would recommend saving your money and buying a Yale Assure Lock 2 or a Kwikset Halo instead. They offer better value and more flexibility. If you are a dedicated home network engineer like myself who values local control above all else and already owns a Z-Wave stick, the Level Lock Plus is a worthy addition to your ecosystem, but be prepared to tinker with the firmware updates manually.
