The SONOFF vs THIRDREALITY smart switch debate highlights two distinct approaches to home automation. Both brands rely on the Zigbee protocol for stable, local control without internet dependency. The primary difference lies in their form factor and application. SONOFF offers a compact module designed for direct wiring into wall boxes, while THIRDREALITY provides a plug-in outlet solution. You must choose between hardwired integration and simple plug-in convenience based on your existing infrastructure.
Key differences
| Aspect | SONOFF Compact Zigbee Smart Switch | THIRDREALITY Zigbee Smart Plug 4-Pack |
|---|---|---|
| Form Factor | Compact module (1.68 x 1.68 x 0.79 inches) | Plug-in outlet (2.6 x 1.5 x 1.1 inches) |
| Smart Home Compatibility | Alexa, Google Home | Apple HomeKit, Google Home, Alexa |
| Wiring Requirement | Neutral Line Required | Not listed |

| Connectivity | Zigbee 3.0 | Zigbee |
Which one should you choose?
Choose SONOFF Compact Zigbee Smart Switch if
- You need a device that fits inside a standard wall mounting box.
- Your setup already includes a neutral wire in the switch box.
- You primarily use Alexa or Google Home for voice control.
Choose THIRDREALITY Zigbee Smart Plug 4-Pack if
- You want to add smart control to a lamp or appliance without wiring.
- You require support for Apple HomeKit automation.
- You prefer a device with ETL safety certification.
Verdict: SONOFF is the better choice if you are installing new switches or replacing existing ones in-wall, provided you have a neutral wire. THIRDREALITY is the practical option for adding smart features to existing outlets or portable devices. Your decision depends on whether you are wiring into a wall box or plugging into an outlet.
SONOFF vs THIRDREALITY Switch Specs
smart home compatibility
THIRDREALITY offers broader ecosystem support for most users. Its smart plug connects with Apple HomeKit, Google Home, and Amazon Alexa. This triad compatibility lets you use Siri, Google Assistant, or Alexa voice commands without extra hurdles. SONONLY lists only Alexa and Google Home compatibility. While this covers most major platforms, it excludes Apple HomeKit users. If you rely on an iPhone or iPad for home automation, THIRDREALITY is the better fit. SONOFF works well if you stick to Android or Amazon devices.
connectivity features
Both brands use the Zigbee 3.0 protocol for stable, local communication. This means your switches work even if your internet goes down. THIRDREALITY adds value by including a Zigbee repeater function in its smart plugs. This helps extend the range of your Zigbee network, which is useful in larger homes with many devices. SONOFF provides a pure end-device function. It does not mention repeater capabilities. For users with large homes or thick walls, the signal boosting from THIRDREALITY can improve overall system reliability without buying extra hardware.
wiring requirement
Installation needs differ significantly between these two products. The SONOFF module explicitly requires a neutral line for power. This is standard for many modern smart switches but can be tricky in older homes where neutral wires are not present in the switch box. THIRDREALITY does not list a specific wiring requirement in its key specs, as it is a plug-in device. You simply insert it into an existing outlet. This makes THIRDREALITY the easier option for renters or older wiring setups where you cannot run new wires or access the electrical box.
physical dimensions
Size matters when fitting devices into tight spaces. The SONOFF module is extremely compact, measuring 1.68 by 1.68 by 0.79 inches. This tiny form factor allows it to fit inside standard EU-type, 86-type, or 120-type wall boxes with room to spare. THIRDREALITY is a plug, measuring 2.6 by 1.5 by 1.1 inches. While compact for a plug, it occupies a full wall socket. If you need to hide the device inside a wall, SONOFF is the only choice. If you just need to control a lamp, THIRDREALITY’s plug design is more practical.
certification
Safety certifications ensure devices meet electrical standards. THIRDREALITY explicitly states its smart plugs are ETL Certified. This independent verification gives you confidence in the product’s electrical safety and build quality. SONOFF’s provided data does not list any specific safety certifications like ETL or UL. While this does not mean the product is unsafe, the lack of listed certification in the specs makes it harder to verify its compliance with North American safety standards compared to the clearly marked THIRDREALITY option.
Which smart switch fits your setup?
Apple HomeKit users needing broad compatibility
The THIRDREALITY plug supports Apple HomeKit alongside Google Home and Alexa. This triad compatibility allows you to use Siri, Google Assistant, or Alexa for voice control. It requires a Zigbee hub or compatible Echo device. The compact design saves space in wall outlets. This makes it ideal for users who rely on multiple smart home ecosystems.
Users with tight electrical boxes
The SONOFF module measures just 1.68 by 1.68 by 0.79 inches. Its tiny size fits easily into small EU-type, 86-type, or 120-type mounting boxes. This compact form factor allows installation in spaces where larger switches would not fit. It connects via Zigbee 3.0 and works with Alexa and Google Home for reliable local control.
Homeowners wanting two-way stair lighting
The SONOFF switch supports two-way control, making it suitable for staircase lighting setups. You can pair it with external switches like rockers or push buttons for flexible control. The device operates on Zigbee 3.0 and requires a hub. It also supports timers and scheduled actions, allowing you to automate lighting routines without internet dependency.

Frequently asked questions
Do SONOFF and THIRDREALITY smart switches need a hub?
Yes, both brands require a separate hub to function. The SONOFF ZBMINIR2 and the THIRDREALITY 3RSP019BZ use the Zigbee protocol, which does not connect directly to your Wi-Fi router. You must have a compatible Zigbee hub to pair these devices with your smart home ecosystem.
Which brand supports Apple HomeKit?
The THIRDREALITY Zigbee Smart Plug supports Apple HomeKit. This allows you to control it using Siri alongside Google Home and Amazon Alexa. The SONOFF Compact Zigbee Smart Switch listed does not mention HomeKit compatibility in its specifications, so it is best for Alexa and Google Home users only.
Which switch is smaller for tight electrical boxes?
The SONOFF ZBMINIR2 is designed for tight spaces. Its compact dimensions measure 1.68 inches in width and length, with a height of 0.79 inches. This small form factor makes it ideal for standard electrical boxes where space is limited. The THIRDREALITY plug is larger and intended for outlet use.
Can I use these devices with voice assistants?
Yes, you can use voice commands with both products. The SONOFF switch works with Amazon Alexa and Google Home. The THIRDREALITY plug supports Apple HomeKit, Google Home, and Amazon Alexa. This gives you flexibility to choose your preferred assistant for controlling lights or plugged-in devices.
What is the difference between a smart switch and a smart plug?
A smart switch replaces the wall switch to control hardwired circuits, while a smart plug goes into an existing outlet. The SONOFF ZBMINIR2 is a switch module for tight electrical boxes. The THIRDREALITY 3RSP019BZ is a plug for lamps or appliances. Choose based on your wiring setup.
Do these devices work without an internet connection?
Local control is possible via the Zigbee hub. Both products rely on the Zigbee protocol for stable communication within your home network. This means they can respond to commands from the hub even if the internet is down, provided the hub itself is powered and connected.
Which option is better for multi-device control?
The THIRDREALITY 4-Pack offers a stable solution for controlling multiple devices. It allows you to manage several plugged-in items without straining your Wi-Fi network. The SONOFF option is a single switch unit. If you need to automate several outlets or lamps, the THIRDREALITY multi-pack is more efficient.
