Descriptions

PEM-U200 can measure

• (1)Voltage: 80~260V AC,
• (2)Current: 0~100A,
• (3)Power: 0~22kW,
• (4)Energy: 0~9999kWh,
• and provide Ultrasonic Ranging Sensor to measure distance (2 ~ 400cm).

WiFi Connections

PEM-U200 uses 2.4GHz IEEE802.11b/g/n to connect to WiFi AP router by Station Mode. If SSID cannot be detected by the WiFi AP Router, PEM-U200 will set itself to Limited WiFi AP Mode for users to configure a new SSID/password, etc. for the new WiFi AP Router by the Web UI.

Connect to Blynk Server and IFTTT

PEM-U200 is connected to the Blynk server, and via Blynk App to remotely monitor Voltage, Current, Power, Energy and distance. PEM-U200 is connected to the IFTTT Server, and users can configure abnormal or alarm condition parameters, and then uses LINE Notify to push abnormal and alarm status. PEM-U200 provides a user friendly Web UI.

Blynk Server

PEM-U200 provide software to connect to the Blynk server by configuring Authentication Tokens (Auth Token) in the device. When the PEM-U200 is connected to the Blynk server through the Internet, the Blynk App. in the Smart phone can then be configured to provide remote monitor and control for the device. The Voltage, Current, Power, Energy and the Ultrasonic Ranging distance can be displayed in Blynk App. Auth Token can be filled in the box in Web UI.

IFTTT

If This Then That, also known as IFTTT, is a free web-based service. Services are the basic building blocks of IFTTT, each service has a particular set of triggers and actions. Triggers are the changes of power measurement states. Actions are the outputs that results from the input from the trigger. Every event can be controlled by the IFTTT applet settings. IFTTT Webhooks API setting can be filled in the box in Web UI.

LINE Notify

IFTTT is used to push notification message to LINE Notify. IFTTT Webhooks is needed to trigger the LINE Notify Action. Same principle can be applied to PushBullet or Gmail for alarm notification.
