Sonoff MINI Extreme Zigbee Dimmer Switch | MINI-ZBDIM

The SONOFF MINI Extreme Zigbee Dimmer Switch (MINI-ZBDIM) is an ultra-compact, professional-grade in-wall smart dimmer module engineered to bring elegant, adaptive lighting control to modern homes. Powered by the robust Zigbee 3.0 protocol, it delivers flawless 1% to 100% trailing-edge brightness adjustments for dimmable LEDs, halogens, and incandescent bulbs without buzzing or flickering. Its miniature form factor hides perfectly behind standard wall switches, converting traditional circuits into automated powerhouses with real-time energy tracking. Packed with high-tier safety safeguards, customizable dimming curves, and intelligent post-load shedding state recovery, it stands as the ultimate, cloud-free lighting upgrade for your local smart home ecosystem.

Overview:

The SONOFF MINI Extreme Zigbee Dimmer Switch (MINI-ZBDIM) represents a major advancement in retrofittable smart lighting systems. Built on premium Silicon Labs EFR32MG21 hardware, this module functions as an active Zigbee mesh router to boost signals, bridge coverage gaps, and strengthen network range across your property. The MINI-ZBDIM accommodates traditional physical rocker or momentary switches, supporting dual 2-way configurations for stairways or long hallways while maintaining continuous, uninterrupted smart automation availability. Designed explicitly for local, subscription-free frameworks, it integrates natively with Home Assistant (ZHA/Zigbee2MQTT), Amazon Alexa, and Google Assistant. With its advanced manual brightness calibration curves and built-in thermal sensor cutoff safeties, it provides a stable and highly personalized lighting control hub built for heavy daily use.

Features:

• Precision 1–100% Brightness Control: Smooth trailing-edge phase dimming creates custom accent moods with seamless transitions and no bulb flickering.
• Zigbee 3.0 Low-Latency Mesh: Operates locally on efficient mesh architecture and acts as a signal-boosting router to eliminate dead zones.
• Real-Time Power Consumption Monitoring: Tracks exact live wattage draw and checks continuous energy metrics straight inside your smart application.
• Ultra-Compact In-Wall Blueprint: Exceptionally tiny profile fits comfortably inside cramped standard South African backing boxes behind existing plates.
• Dual Location 2-Way Switching Support: Connects easily to up to two external manual switches to command single light loops simultaneously from separate rooms.
• Advanced Brightness Calibration Matrix: Easily configure manual minimum brightness levels to perfectly match the specific dimming thresholds of different bulb brands.
• Configurable Power-On Memory States: Define exact light behavior (ON, OFF, or Last State) to prevent lights from flaring up unguided when mains return after a load shedding cut.
• Built-In Advanced Thermal Protection: Integrated internal temperature sensor monitors heat thresholds 24/7, auto-shutting down loops if overheating flags occur.

Broad Lamp Compatibility for Effortless Home Retrofitting

Eliminate the frustrating guessing game of finding matching smart fixtures. The MINI-ZBDIM supports an extensive range of traditional and modern residential lights—including up to 200VA dimmable LEDs, 400W halogens or incandescent bulbs, and 200W electronic transformers—making it an all-in-one upgrade for your home's current lighting setup.

*Note: Connected LED fixtures must be explicitly marked as dimmable to prevent micro-current humming or performance degradation.

Flawless, Pro-Grade Dimming Across the Entire Range

— Create the perfect environment for a relaxing evening lounge or crisp morning workspace. Utilizing premium trailing-edge phase-cut technology, the module delivers linear, flicker-free dimming curves, ensuring smooth transitions between brightness levels without annoying buzzing or strobing.

Adaptive Brightness Calibration Built for Your Bulbs

- Fine-tune your lighting response to eliminate flickering entirely. Because different bulb brands trigger power thresholds differently, the MINI-ZBDIM includes an intelligent automatic or manual brightness calibration setup. Easily lock in the lowest stable dimming point to avoid cutouts or ghosting at low percentages.

Your Invisible Energy Detective: Real-Time Power Monitoring

Take charge of your electricity bill with live tracking metrics. The instant you dim your lights, the MINI Extreme recalculates and synchronizes the active power draw, giving you detailed insights into your home's efficiency right inside your smart home dashboard. It is a vital tool for optimizing solar setups or tracking inverter reserves.

Dual-Location 2-Way Switching with Your Original Toggles

Control a single lighting loop from two different locations without complicated, messy rewiring. The module easily pairs with dual mechanical rocker switches or momentary push buttons, letting you turn on or dim lights from the bottom of the stairs and shut them off from the top bedroom landing with ease.

Advanced Automation Schedules and Intelligent Timers

Let your home manage itself with autonomous lighting schedules. Set customized recurring alarms, automated countdown timers, or gentle sleep-fading sequences that automatically cycle your lights based on specific times of day, motion triggers, or sunset conditions.

Hands-Free Freedom with Smart Voice Integration

Control your lighting using simple voice commands. Compatible with major platforms like Amazon Alexa and Google Assistant via your Zigbee hub, you can dim the lounge, check light status, or adjust rooms instantly without lifting a finger.

Reinforce and Amplify Your Local Zigbee Mesh Range

Eliminate dropping signals and sluggish device responses for good. Built on the mains-powered Zigbee 3.0 protocol, the MINI-ZBDIM automatically acts as a dedicated mesh network router. It continuously relays and strengthens signals across distant sensors, switches, and remotes to keep your entire network stable.

Advanced Overheat Protection for Complete Safety

Keep your home safe with industrial-grade, hardware-level protection. The dimmer features an integrated TC temperature sensor that actively monitors working conditions 24/7. If excessive heat or overload conditions are detected, it issues a warning and cuts power automatically to protect your home.
