Get to know your device
All of the ports are labeled on the back of the main unit.
- The 3.5mm L1/A, L2/B, and L3/C audio ports on the top of the main unit are the inputs for the Main CTs.
- The 2.5mm audio ports on the sides of the main unit are the inputs for the Sub CTs
- The port on the bottom of the main unit are the input for the power cable
Reset Button
Reset. Press and hold the reset button for 5 seconds until the LED indicator
flashes red 3 times quickly to restore the Power Meter to default factory
settings (energy data will not be cleared).
If you want to clear the energy data, please delete the device and wipe data
on the app and add it again.
LED indicator
The LED status gives the following information of the Power Meter:
LED Status / What it means
- Green LED blinking /Wait for pairing
- Green LED solid on /Device has connected to the cloud.
- Red LED solid on /Device is connected to the router but failed to connect to the cloud.
- Red LED blinking/ Wi-Fi has been configured but failed to connect to the router.
Installation
Important safety information!
- The Power Meter must be installed and serviced only by a qualified electrical personnel.
- Do not touch the terminals of the device during testing.
- Make sure that the power supply is off before connecting or disconnecting it to an auxiliary device.
- Always use a properly rated voltage sensing device to confirm power is off.
- Replace all devices, doors and covers before applying power to the equipment. Failure to follow these instructions will result in death or serious injury.
Turn off power
You need to turn off the main breaker in your electric panel to shut off all of the power in your home (However, the service mains are always live!). Then remove the screws securing the cover to the panel to access the circuit breakers.
Find a spot for a Power Meter
Find a spot that works for you. You can fit it within your electrical panel or you can use a mounting bracket to fix it on the wall outside the electrical panel if there is no room for your electrical panel.
Install the antenna
Locate the External Antenna outside the electrical panel to ensure that the Power Meter signal is not blocked by metal (The base of the antenna has magnetic and can be adsorbed on iron materials). After that, screw the External Antenna to the Antenna connector.
If you install the Power Meter into the electrical panel, you can use a screwdriver to punch out a knockout cover in the electrical panel. Then feed the External Antenna cable through the hole.
Clamp Main CTs around service mains
- Open the clasps on the Main CTs(3.5mm audio plug) to see the arrow (P1→P2) or (K→L) or you can find it on the sticker on the outside of the clamp. This is the direction of CT.
- Clamp one Main CT on each main service lines. Make sure the arrow on the CT must point towards the breakers! Your system may have 1, 2, or 3 main service lines, and a corresponding number of Main CTs are required.
- If you have Line/Service-side tap solar, the Main CT must be clamped between the electricity meter and incoming feeds from inverter.
- Insert each 3.5mm audio plug of Main CT into the corresponding audio jack on the top of the Power Meter:
- The CT measuring the L1/A line should plug into the audio jack labeled L1/A.
- The CT measuring the L2/B line should plug into the audio jack labeled L2/B.
- The CT measuring the L3/C line should plug into the audio jack labeled L3/C.
Please refer to the picture below for the number and location of Main CTs in different systems:
Connect the power
- Connect the power cable into the bottom of the main unit until it clicks into place securely.
- Secure N wire from the power cable to the neutral bus bar and L1 wire to the L1/A breaker pole.
If your system is 3-Phase, secure the L2, L3 wire corresponding to L2/B, L3/C breaker pole.
3-Phase
If your system is Split-Phase, only secure the L2 wire to L2/B breaker pole.
L3 wire need to connect to the neutral bus bar.
If your system is Single Phase, the L2 and L3 wire need to connect to the neutral bus bar.
Single Phase
Clamp Sub CTs around the circuit
If you don’t have Sub CTs(2.5mm audio plug), skip this step.
- Open the clasps on the Sub CTs to see the arrow (P1→P2) or (K→L) or you can find it on the sticker on the outside of the clamp. This is the direction of CT.
- Clamp each Sub CTs around the circuit you wish to monitor. Make sure the arrow on the CT must point towards the load or Inverter!
- Note: If the circuit you are monitoring can generate energy such as Inverter, etc., after all the wiring is completed, please manually set the phase of the circuit in the app settings, otherwise the power measurement will be incorrect.
- Insert each 2.5mm audio plug of Sub CT into the audio jack on the side of the Power Meter. Remember the number of the audio jack connected to the circuit you are measuring, and you may need to match it on your app.
