TOVMT is a 2-pole smart metering switch designed for DIN-rail distribution board applications, combining basic switching control with metering visibility in a compact form.
——L-L (Line–Line) wiring: suitable for line-to-line supply scenarios
——L-N (Line–Neutral) wiring: suitable for line-to-neutral supply scenarios
TOGW is a gateway designed to extend smart device connectivity in projects where the uplink may vary. It can use Wi-Fi or 4G as the upstream connection, and provide Bluetooth and Zigbee on the local side to connect compatible smart devices.
——Flexible uplink: choose Wi-Fi or 4G depending on site conditions.
——Local device onboarding & networking: supports Bluetooth + Zigbee for connecting smart devices locally via the gateway.
——Simplifies deployment: ideal for sites where you want a consistent gateway layer while keeping end devices on Zigbee/Bluetooth.
TOVTH is a DIN-rail smart switch designed for temperature and humidity monitoring + automatic control in distribution boards and cabinet applications. It helps partners add a simple “environment layer” (temp/humidity) to projects, without changing the overall panel architecture.
TOWPS is a smart waterproof box switch designed for outdoor and harsh-environment installations, where a standard DIN-rail device is not suitable. It combines protected enclosure design with smart control, making it a practical option for projects like outdoor lighting, pumps, signage, garden systems, and wet-area equipment.
