EM-126T multifunctional timer relay is a microprocessor-based device designed for home automation, functioning as a smart plug.

EM-126T Features:

• Enables scheduled or manual switching of loads, while protecting loads from various voltage faults and power overloads.
• Includes a temperature sensor for measuring ambient air temperature, allowing EM-126T to control heating or cooling devices based on measured air temperature.
• Equipped with a single control button (for entering Wi-Fi setup mode or manual load control) and two indicators (to show fault presence, load status, and Wi-Fi connection status).
• Collects real-time energy consumption data and transmits it to the "my.overvis.com" server, where saved reports can be viewed for a week, month, or year.

Enables electricity savings by controlling climate and water heating devices according to a pre-planned schedule. Based on energy consumption data, the "my.overvis.com" server can suggest optimal schedule settings.

Main Functions:

• Measures network voltage and frequency
• Measures ambient air temperature
• Measures current consumed by the load
• Measures power consumed by the load
• Records energy consumption of the load
• Protects the load from voltage faults in the network
• Provides over-current and over-power protection for the load
• Real-time clock with up to 5 days of power reserve (in case of power outage)
• Automatic time synchronization with SNTP time server
• Automatic load management based on user-defined schedule
• Vacation scheduling (with program lock)
• Load operation time restriction
• Manual load control from the front panel
• Manual control lock after a set time period (child lock)
• LED brightness adjustment

Operating Modes for EM-126:

The device can operate in three modes:

• Normal operation mode
• Manual control mode
• Wi-Fi connection setup mode

Normal Operation Mode:

EM-126T connects to the specified Wi-Fi access point, monitors network parameters (voltage and current) to protect the load, and manages load switching according to the user-defined schedule.

In case of a fault (over-current, over-voltage, or under-voltage), EM-126T performs an emergency disconnection of the load.

Manual Control Mode:

If the user manually changes the load status (by pressing the button on the front panel or remotely via the server at my.overvis.com), the EM-126T blocks the current scheduled event and enters manual control mode.

Upon the next scheduled event, EM-126T returns to normal operation. Manual control status is retained if the device is powered off.

Wi-Fi Connection Setup Mode:

In this mode, EM-126T creates its own access point named "EM-126T_xxxxxxxx" (where xxxxxxxx is the unique code of the device). The user can connect to this access point and access the Wi-Fi setup in a web browser (e.g., Opera, Google Chrome, Firefox) by going to "em.com" or "http://192.168.4.1" to configure Wi-Fi settings.
