Take smarter control of your lights and appliances with the Sonoff MINI-ZB1GSP<\/a><\/strong>, also known as the MINI ONE PM is a compact Zigbee 3.0 smart switch with built-in power and energy monitoring.<\/p>\n Designed to fit neatly behind compatible wall switches or inside junction boxes, this powerful single-channel relay combines up to 16A switching, detailed electricity monitoring, advanced safety protection and Zigbee mesh network expansion in one compact device.<\/p>\n Whether you want to automate a light, monitor an appliance, track electricity usage or build smarter energy automations in Home Assistant, the Sonoff MINI-ZB1GSP provides the flexibility and insight you need.<\/p>\n Control compatible lighting circuits and appliances remotely while retaining convenient physical control through an external wall switch.<\/p>\n With support for loads of up to 16A resistive<\/strong>, the MINI-ZB1GSP is suitable for a wide range of smart home applications where a compact, high-capacity Zigbee relay is required.<\/p>\n Use it for applications such as:<\/p>\n Always ensure that the connected load and installation comply with the device’s electrical specifications and local wiring regulations.<\/p>\n Go beyond simple on\/off control.<\/p>\n The built-in energy monitoring functionality allows you to track electrical activity and better understand how your connected devices consume power.<\/p>\n Monitor data such as:<\/p>\n View usage trends and historical information through the compatible smart home ecosystem to identify energy-hungry appliances and make smarter decisions about electricity consumption.<\/p>\n The MINI ONE PM supports bidirectional energy monitoring<\/strong>, making it useful for applications where energy may flow in either direction.<\/p>\n This capability can be particularly useful when monitoring compatible renewable or energy-generation systems, allowing you to track both consumption and generated energy where supported by the installation and connected platform.<\/p>\n This adds another layer of flexibility beyond traditional smart switches with basic one-way energy monitoring.<\/p>\n Make your energy data more meaningful by using supported electricity pricing and tariff tools.<\/p>\n Configure electricity rates and, where supported, time-based pricing to better estimate the cost of running connected equipment.<\/p>\n This can help you:<\/p>\n The MINI-ZB1GSP can help identify changes in appliance power consumption.<\/p>\n This opens the door to useful automations and notifications based on the behaviour of connected devices.<\/p>\n For example, you may be able to create notifications or automations when a compatible appliance completes its operating cycle based on changes in power consumption.<\/p>\n Potential applications include:<\/p>\n This allows your smart home to respond to what an appliance is actually doing \u2014 not simply whether the switch is turned on.<\/p>\n Because the MINI ONE PM is mains-powered, it can also act as a Zigbee router<\/strong>, helping strengthen and extend your Zigbee mesh network.<\/p>\n Instead of simply connecting to your Zigbee coordinator, the device can help relay Zigbee communications between compatible devices.<\/p>\n This can help:<\/p>\n It is an excellent choice for users expanding a Home Assistant, Zigbee2MQTT, ZHA or eWeLink Zigbee network<\/strong>.<\/p>\n Protect your connected circuit with configurable safety features.<\/p>\n The MINI-ZB1GSP supports protection functions for conditions such as:<\/p>\n Where configured and supported, the device can automatically disconnect the connected load when defined thresholds are exceeded.<\/p>\n This provides an additional layer of protection and makes the MINI ONE PM particularly useful for monitored appliance circuits.<\/p>\n Upgrade your home without losing traditional manual control.<\/p>\n The MINI ONE PM can be connected to compatible external wall switches, allowing household members to continue using the physical switch while also benefiting from smart control and automation.<\/p>\n Depending on the configuration, supported features include:<\/p>\n Detach Relay mode<\/strong> allows the external switch to act as a smart trigger while keeping the relay state independent \u2014 particularly useful when controlling smart bulbs or triggering automations.<\/p>\n The Sonoff MINI-ZB1GSP integrates into a Zigbee smart home through a compatible coordinator or gateway.<\/p>\n Use it as part of your wider automation system with compatible platforms such as:<\/p>\n Create automations based on schedules, sensor readings, energy usage or changes in appliance power consumption.<\/p>\n For example:<\/p>\n If the washing machine’s power consumption drops below a chosen level, send a notification that the wash cycle may be complete.<\/strong><\/p>\n<\/blockquote>\n Or:<\/p>\n Automatically switch off a device if its power consumption exceeds your chosen safety threshold.<\/strong><\/p>\n<\/blockquote>\n Despite its powerful feature set, the MINI ONE PM remains compact enough for many retrofit installations.<\/p>\n With dimensions of approximately 39.5 \u00d7 33 \u00d7 16.8 mm<\/strong>, it can be installed behind compatible wall switches or inside suitable junction boxes.<\/p>\n For easier installation, a mounting box with sufficient depth and space for wiring is recommended.<\/p>\n A neutral wire is required for operation.<\/strong><\/p>\n The Sonoff MINI-ZB1GSP is an excellent choice for:<\/p>\nWhy Choose the
