SONOFF SNZB-01P Review (2026): Why This $12 Zigbee Button Still Crushes the Competition

Updated February 24, 2026

In a smart home world obsessed with the latest standards like Matter, doing a SONOFF SNZB-01P review in 2026 might feel like a throwback. But let’s be real: this tiny-but-mighty Zigbee button is still a rock-solid, indispensable workhorse for any Home Assistant setup. For years, it’s been the go-to budget-friendly solution for controlling scenes, lights, or any automation with a simple click. And its relevance hasn’t faded—it’s become an essential for those of us who prioritize fast, local, and reliable control. You can grab one for a killer price on the official Sonoff store.

Is the Sonoff SNZB-01P Still Worth It in 2026?

The short answer: a resounding yes. While the market is flooded with shiny new Matter over Thread alternatives, the Zigbee 3.0 protocol remains a cornerstone of local-first smart homes. The SNZB-01P stands out for three key reasons that keep it on top:

• Unbeatable Value: It’s virtually impossible to beat on price. You can scatter these physical control points all over your house for a fraction of the cost of its modern counterparts.
• Rock-Solid Reliability: On a well-managed Zigbee network with a powerful coordinator like the SMLIGHT SLZB-06, its latency and response time are instantaneous. It’s 100% cloud-free, ensuring it works flawlessly even when your internet is down.
• Epic Battery Life: The CR2477 battery it uses is massive for a device this size. In my long-term testing and based on community feedback, its real-world battery life easily surpasses two years—a benchmark many newer gadgets still can’t hit.

Key Tech Specs of the SNZB-01P

The hardware hasn’t changed, but our understanding of its long-term performance has. Here’s a look at its most relevant specs from a 2026 perspective.

Home Assistant Integration: The Perfect Match

The SNZB-01P’s true power is unleashed when you pair it with Home Assistant. Forget the eWeLink app; this button was born for 100% local control. The process is dead simple:

1. Make sure you have a Zigbee coordinator, like the popular Sonoff Zigbee 3.0 USB Dongle Plus, connected to your Home Assistant instance.
2. Put your integration (ZHA or Zigbee2MQTT) into pairing mode.
3. Press and hold the button on the SNZB-01P for about 5 seconds until the LED blinks.
4. Home Assistant will automatically discover it and expose an entity with sensors for the action and battery level.

Once integrated, you can use its three actions (single, double, long) to trigger any automation. For example, to toggle a light with a single press, the YAML automation is as simple as this:

alias: 'Office Light with Sonoff Button'
description: 'Toggles the office light with the SNZB-01P'
trigger:
  - platform: device
    device_id: your_button_device_id
    domain: zha # or mqtt if you use Zigbee2MQTT
    type: remote_button_short_press # or the action name exposed by your integration
condition: []
action:
  - service: light.toggle
    target:
      entity_id: light.office_light
mode: single

The SNZB-01P and Matter Compatibility in 2026

It’s crucial to understand this: the Sonoff SNZB-01P is not a native Matter device. It runs on Zigbee. However, thanks to the magic of bridges, we can make it fully compatible with a Matter ecosystem.

Home Assistant is the perfect example of a “Matter bridge”. By integrating the SNZB-01P button into Home Assistant via Zigbee, Home Assistant can then “expose” that button to other systems like Apple Home or Google Home using its Matter implementation. In practice, this means you can use this dirt-cheap Zigbee button to control native Matter devices in your home, as long as Home Assistant is the central brain.

SONOFF SNZB-01P (2026) vs. Matter over Thread Alternatives

To put it in perspective, let’s see how this Zigbee classic stacks up against the Matter over Thread alternatives that have gained popularity in 2026.

Long-Term Security, Battery, and Performance

The security of a Zigbee ecosystem, when managed locally with Zigbee2MQTT or ZHA, is extremely high. By using a unique network key and not relying on external servers, you create a private network for your IoT devices—a key concept for proper home network segmentation.

As I mentioned, the CR2477 battery is its secret weapon. While many new devices struggle to hit the one-year mark, it’s not uncommon for an SNZB-01P to still be chugging along perfectly after two years. Its performance is consistent: you press it, the action happens. Simple, effective, and hassle-free.

Price and Where to Buy

One of the biggest advantages of the Sonoff SNZB-01P is still its price. You can usually find it for under $12, making it an impulse buy for expanding physical control in your smart home. The best bet is usually the official ITEAD (Sonoff) store to guarantee authenticity and support.

Plus, as a Tecnoyfoto reader, you can get a 10% discount on your purchase by using the coupon code TECNOYFOTO in the official store.

The Verdict: My Final Take on the SONOFF SNZB-01P in 2026

After years of using this button and watching the market evolve, my conclusion is crystal clear: the Sonoff SNZB-01P is still a masterclass purchase for any Home Assistant user. It’s the “foot soldier” of the smart home: cheap, incredibly reliable, and with a battery life that puts far more expensive and modern devices to shame.

If Home Assistant is your smart home’s brain and you already have (or are planning) a Zigbee network, don’t hesitate. This button gives you instant, local, physical control over your automations for a ridiculously low cost. While Matter over Thread alternatives might be the future, the practical reality for many of us today lies in the robustness and maturity of ecosystems like Zigbee. And in that arena, the SNZB-01P is still the undisputed king.
