WEM3046TE Quickstart

If you are looking for a power meter, please read this article first. It will help you quickly confirm whether IAMMETER products meet your requirements. How to choose the power meter with regard to your requirements

1. Hardware Installation

Note:

WEM3046TE is designed for retrofit projects and double-CT installation scenarios. Unlike WEM3046T, which connects third-party xxx:5A CTs directly to the terminal, WEM3046TE includes three 5A split-core CTs. These CTs are typically clamped onto the existing CT circuits on site, making WEM3046TE suitable for site retrofit projects where the original wiring should remain unchanged.

How to connect WEM3046TE to the existing CT circuit

WEM3046TE is designed for retrofit projects where 5A CTs are already installed on site and the original CT wiring should remain unchanged. The included split-core 5A CTs can be clamped onto the existing CT secondary circuit for non-intrusive installation.

Note: This is the most typical application scenario of WEM3046TE. It is suitable for retrofit projects where the existing CT circuit is already available in the distribution box.

3. Wi-Fi Setup

There are two ways to configure the meter's Wi-Fi settings. Setting up by mobile app is recommended. However, you can also set it up in the browser if you encounter any problems when using the app.

3.1 Set up by mobile app

Step 1, scan the QR code and download the mobile app.

Step 2, search and connect your phone to the iMeter access point signal iMeter_xxxxxxxx.

Step 3, open the app and find the iMeter.

Tips: If the app prompts "Invalid device version", you need to set up the Wi-Fi network by browser, same as 3.1 WEM3162 QuickStart

Step 4, select the SSID of your home Wi-Fi network.

Step 5, enter the password and save. After the Wi-Fi settings are configured successfully, you will see the IP address allocated to the iMeter.

3.2 Set up in the browser

If you have successfully set up the meter's Wi-Fi settings in step 3.1, you can skip this section.

4. Sign up by Mobile App

Tips: SN is the unique serial number of your iMeter. You can copy it from the iMeter's access point signal (iMeter_xxxxxxxx, where xxxxxxxx is the SN).

5. Set the Time Zone

Tips: The time zone must be set according to where your meter is located for correct data display and time-based reports.

6. Edit the Meter Type

Tips: It is "single phase" as the default meter type in IAMMETER. You need to change the meter type to "Three Phase".

7. Set the Use Type of Each CT

Tips: Please set the use type of each CT according to the actual CT installation. For example, if you clamp the CT of phase A onto the grid side, then set its use type as "grid".

9. How to know that the meter already connected to your router

1. After the meter connects to your home Wi-Fi router, the iMeter access point signal (iMeter_xxxxxxxx) disappears for security reasons.
2. You can find your iMeter in the network list of your PC connected to the same home Wi-Fi network.
3. If you want to see the iMeter signal again, you can switch off your Wi-Fi router or move the meter to a place where your router coverage is unavailable.
