This GreenSPD App is applied in the Wi-Fi connection settings for Watchful EyE Smart Surge Protective Device－Smart GreenSPD series. For example, after the Smart GreenSPD is connected to Wi-Fi successfully, the working condition of the Smart GreenSPD and surge counts will be periodically transmitted to the GreenSPD Cloud, A professional personnel can use an internet browser for remote accessing to www.greenspd.com for real-time viewing working conditions of the Surge Protective Devices.
Setting Steps:
1. Display App GreenSPD
2. Log in with password of Wi-Fi connection.
3. Connect Smart SPD to power supply: connect the Micro USB port of Smart GreenSPD to a USB power supply
4. The green, orange and red LED lights on the Smart GreenSPD panel will be steady-on for 2 seconds, then followed by the green LED light blinking slowly; if the Smart GreenSPD fails to connect to Wi-Fi router in 20 seconds, the green LED light will blink quickly.
5. While the green LED light is blinking quickly, continuously press RESET button for 5 seconds. Release the button until the orange LED light blinks quickly instead.
6. Click TICK button on the App interface.
7. Wait for up to 40 seconds, the user name and password of Wi-Fi connection is being written into the Smart GreenSPD in this process.
8. When the green LED light blinks, Wi-Fi password setting is completed and the Smart GreenSPD is being connected to Wi-Fi router.
9. If the green LED light is Steady-on, the Smart GreenSPD is connected to Wi-Fi router properly.
10. If the orange LED lights are Steady-on, TCP/IP is connected properly.
11. If the red LED is steady-on, it indicates that the surge protector is faulty or surge counts increasing. Press RESET to recover. If the red LED is still Steady-on, it indicates fault, requiring replacement of the surge protector.
Smart GreenSPD LED indicators:
I Red LED light
1. Off: SPD works properly
2. Steady-on: SPD is defective
II Green LED light
1. Off: no access to Wi-Fi router
2. Blink slowly: in the access to Wi-Fi router
3. Steady-on: Smart GreenSPD is connected to Wi-Fi router properly
4. Blink quickly: Smart GreenSPD cannot be connected to Wi-Fi, check if the Wi-Fi router works normally; reset the username and password of Wi-Fi connection.
III Orange LED light
1. Off: TCP/IP can’t be connected.
2. Steady-on：TCP/IP is connected properly.
3. Blink slowly：TCP/IP is sending data, the frequency of blinking is based on the frequency of data sending, e.g. if data is sent once every minute, the orange LED light will blink slowly once every minute accordingly.
4. Blink quickly：When press the RESET button continuously, LED lights will blink quickly, requiring the App to reset username and password of Wi-Fi connection.
Memo: four status of LED indicators:
1. Off
2. Steady-on
3. Blink slowly: LED lights blink in a rate of twice a second
4. Blink quickly: LED lights blink in a rate of 5 times a second
