graffiti wifi smart 3-way electric meter transformer lcd display 1-way 16a on-off device over-temperature safety alarm

 Six core selling points, creating ultimate safety and intelligence

1. Professional-grade accurate measurement | 3-channel independent 100A large current detection

• Integrated with three high-precision current transformers (CTs), each can independently measure up to 100A of current, making it easy to monitor the power usage of household main switches, large appliances (such as air conditioners, electric water heaters), and commercial establishments.

• Wide Range and High Precision: Measurement accuracy up to ±2%, supports a wide voltage range of 80V-260V, suitable for global use.

2. Seamless Intelligent Ecosystem | Native Doodle WiFi, 5-second Fast Network Configuration

• No gateway required, directly connect to the cloud: Built-in graffiti WiFi module, directly connect to the home router, and achieve global remote control through the "Tuya Smart" or "Smart Life" APP.

3. Remote circuit control | Built-in reliable 16A relay switch

• One-click mobile phone switch: Remote control of the connected electrical switch or large appliances through the APP, convenient management and energy-saving.

• Overload Protection: The relay has a rated current of 16A, which meets the mainstream home electrical circuit standards and has an overcurrent protection mechanism.

4. Active Safety Defense | Real-time Overheat Alarm, Preventing Potential Fires

• Built-in high-sensitivity temperature sensor: 7x24-hour monitoring of the temperature inside the electrical box or at the connection points of the equipment.

• Double alarm mechanism: When the temperature exceeds the safety threshold (e.g., 65°C), the APP immediately pushes an alarm notification, and it can be set to automatically link with the machine to break the 16A relay, thereby cutting off the risk at the source.

5. Solid Safety Foundation | V-0 Grade Fire-Resistant Material

• The shell is made of PC+ABS alloy material, meeting the UL94 V-0 flame retardant standard. It is not easy to burn when exposed to open flame, and will extinguish when removed from the flame, effectively preventing the spread of fire caused by internal electrical failures, providing hardware-level security for your property and personal safety.

6. Local clear display | High-definition LCD screen

• Data at a glance: No need to open the phone, you can view the total electricity consumption, current power, voltage, current, temperature, and on/off status in real time on the local LCD screen of the device, making it convenient for daily inspections.
