Professional Smart Control for High-Power Electrical Circuits<\/h2>\n

Take intelligent control of your home’s most demanding electrical loads with the Sonoff Basic ZB1GSP Zigbee DIN Rail Smart Switch. Designed for installation inside standard electrical distribution boards, this professional-grade 32A Zigbee 3.0 smart relay combines powerful switching capabilities, advanced safety features, and real-time energy monitoring in a compact DIN rail module.<\/p>\n

Whether you’re automating a geyser, monitoring an EV charger, controlling underfloor heating, or managing commercial electrical equipment, the Basic ZB1GSP delivers reliable performance, precise power insights, and seamless smart home integration.<\/p>\n

\n
\n<\/div>\n

Built for High-Power Applications<\/h2>\n

Unlike standard smart plugs or compact relays, the BASIC-ZB1GSP is engineered to control demanding electrical circuits up to 32A (100\u2013240V AC)<\/strong>.<\/p>\n

Ideal for:<\/p>\n

    \n
  • EV chargers<\/li>\n
  • Electric geysers and water heaters<\/li>\n
  • Heat pumps<\/li>\n
  • Underfloor heating systems<\/li>\n
  • Pool pumps<\/li>\n
  • Air conditioning systems<\/li>\n
  • Workshop equipment<\/li>\n
  • High-power appliances<\/li>\n
  • Commercial and industrial installations<\/li>\n<\/ul>\n

    Its robust relay design makes it an excellent solution wherever reliable high-current switching is required.<\/p>\n

    \n
    \n<\/div>\n

    Standard DIN Rail Installation<\/h2>\n

    Designed for professional electrical installations, the BASIC-ZB1GSP clips directly onto a standard 35 mm DIN rail<\/strong> inside distribution boards.<\/p>\n

    Benefits include:<\/p>\n

      \n
    • Fast installation<\/li>\n
    • Neat, professional appearance<\/li>\n
    • No drilling or modification required<\/li>\n
    • Suitable for residential, commercial, and industrial applications<\/li>\n
    • Easy integration into existing electrical panels<\/li>\n<\/ul>\n

      Its compact footprint helps maximise available space inside crowded distribution boards.<\/p>\n

      \n
      \n<\/div>\n

      Real-Time Energy Monitoring<\/h2>\n

      Understand exactly how much electricity your equipment is using.<\/p>\n

      Monitor:<\/p>\n

        \n
      • Live power (W)<\/li>\n
      • Voltage (V)<\/li>\n
      • Current (A)<\/li>\n
      • Total energy consumption (kWh)<\/li>\n<\/ul>\n

        Access daily, monthly, and historical energy data to:<\/p>\n

          \n
        • Identify high-energy appliances<\/li>\n
        • Reduce electricity costs<\/li>\n
        • Optimise automation schedules<\/li>\n
        • Monitor long-term energy trends<\/li>\n
        • Export usage records where supported<\/li>\n<\/ul>\n

          Energy monitoring is especially valuable for large loads such as geysers, EV chargers, and heating systems.<\/p>\n

          \n
          \n<\/div>\n

          Advanced Double-Pole Isolation<\/h2>\n

          Safety is one of the standout features of the BASIC-ZB1GSP.<\/p>\n

          Unlike many smart relays that disconnect only the live conductor, this unit features double-pole switching<\/strong>, simultaneously isolating both Live and Neutral<\/strong>.<\/p>\n

          Benefits include:<\/p>\n

            \n
          • Improved electrical safety<\/li>\n
          • Complete circuit isolation<\/li>\n
          • Safer maintenance procedures<\/li>\n
          • Reduced risk of unintended energised conductors<\/li>\n<\/ul>\n

            This makes the BASIC-ZB1GSP particularly well suited to professional installations and critical electrical loads.<\/p>\n

            \n
            \n<\/div>\n

            Intelligent Overload Protection<\/h2>\n

            Protect your connected equipment with configurable protection settings.<\/p>\n

            Set custom limits for:<\/p>\n

              \n
            • Voltage<\/li>\n
            • Current<\/li>\n
            • Power<\/li>\n<\/ul>\n

              If any threshold is exceeded, the relay can automatically disconnect the load, helping to protect equipment from abnormal electrical conditions and reducing the risk of damage.<\/p>\n

              \n
              \n<\/div>\n

              Reliable Zigbee 3.0 Connectivity<\/h2>\n

              The BASIC-ZB1GSP communicates using Zigbee 3.0<\/strong>, providing fast, stable, low-latency local communication.<\/p>\n

              Benefits include:<\/p>\n

                \n
              • Reliable local operation<\/li>\n
              • Low wireless interference<\/li>\n
              • Fast response times<\/li>\n
              • Excellent network stability<\/li>\n
              • Low power consumption<\/li>\n<\/ul>\n

                Unlike Wi-Fi devices, Zigbee creates a self-healing mesh network that becomes stronger as additional powered devices are added.<\/p>\n

                \n
                \n<\/div>\n

                Strengthen Your Zigbee Mesh<\/h2>\n

                Because the BASIC-ZB1GSP is permanently powered, it also functions as a Zigbee router<\/strong>, helping extend and strengthen your Zigbee network.<\/p>\n

                This improves communication for nearby battery-powered Zigbee devices, reduces dead spots, and enhances the reliability of your entire smart home.<\/p>\n

                \n
                \n<\/div>\n

                Powerful Smart Automation<\/h2>\n

                Integrate the BASIC-ZB1GSP into your favourite Zigbee platform to create intelligent automations.<\/p>\n

                Examples include:<\/p>\n

                  \n
                • Automatically heat your geyser during off-peak electricity tariffs<\/li>\n
                • Monitor EV charging energy usage<\/li>\n
