Smart ZigBee Energy Meter Bidirection 1, 2 Channel with Current Transformer Clamp App Monitor Power 80A 110V/240V 50/60Hz

NOTE

Customer review: This product is a good choice when used together with Home Assistant on Zigbee2mqtt. For it to function properly, you need to stop z2m and change >TZE28C1000000_81yrt3lo to >TZE284_81yrt3lo. Make the changes in the database of Zigbee2mqtt through the "file editor" and then restart.

Q: Why can't my device connect to 2.4G WiFi?
A: This is a ZigBee device, it can't connect WIFI signal directly, but require a Tuya ZigBee gateway as hub to work, please make sure you have a Tuya ZigBee gateway to work with this item.

Q: Is it ZigBee 3.0 standard Item?
A: No. It's Tuya ZigBee device, not with ZigBee 3.0. Standard, so it can only work with Tuya ZigBee Gateway.

Q: Is this device compatible with HomeAssistant?
A: No, it's not compatible. You need configure it with ZigBee2MQTT first, then it can work with Home Assistant. If you don't know how to configure it, please use the Tuya Smart or Smart Life APP.

Q: Is this device compatible with Zigbee2MQTT?
​A: Sure.. If you have any question about how to figure it, please be free to contact with customer service, we will make guide.

This device is not compatible with Zigbee Home Automation.

Hi, friend. Do you have a Tuya Zigbee Gateway?
You need to prepare a Tuya Zigbee Gateway for this device, because Zigbee device can not receive 2.4G wifi signals.

If you don't have a Tuya gateway, you can click on the picture below to buy one.

App can display Channel A and B Real-time power, current, voltage for Forward and Reverse direction clrealy

The meter is allow to do calibration

2 Channels For Reverse and Forward direction

1 Channle or 2 Channels are available to Choose
And you can read from App for each Channel

- Real-time total power of 2 channels of reverse and forward direction
- Power for Channel A and B Separately(W)
- Current(mA)
- Voltage(V),
- Power factor, and Frequency(Hz)

Electricity Statistic for each channel in Forward and Reverse direction.

Hourly Elec. (KWh)
Daily Elec. (KWh),

Electricity Statistic Channel A , B Separately and Total daily monthly, yearly Reverse and Forward Direction

Automation , It allows to make a Scene for this device working with other tuya devices

Set Automation for the Measured Device ,
For example, If Power or Current Is over the Value, then other tuya device starts to work .

Wiring Diagram

1. To measure the power 'from Grid' and 'To Grid'
Please note to make sure the circuit mesaured is in the same phase as the circuit power to the module.

2. Measure the power consumption.
Please note to make sure the circuit mesaured is in the same phase as the circuit power to the module.

Non-connect to Be Safe, Easy and Safe to Install

No need to change the wires, Just put the wire into the clamp, then it can measure, very easy.

Small Size Module , Easy to Install

We guarantee good quality, every product will be tested before delivery. Not before Order

Q&A

Q : After I configure it with App , why App shows 'shutdown' ?
A : Only if you put a device's wire (either live wire or neutral wire, not both) in the clamp, and turn on the device, then the clamp can sense the current, and App will show it is working

Q : I suppose P= U*I, why the value shows on App is not correct ?
A : Please consider the cos(Φ).
Because As resistances do not produce any phasor difference (phase shift) between voltage and current waveforms, all the useful power is delivered directly to the resistance and converted to heat, light and work. Then the power consumed by a resistance is real power which is fundamentally the circuits average power.
To find the corresponding value of the real power the rms voltage and current values are multiplied by the cosine of the phase angle, Φ as shown.
Real Power P = I2R = V*I*cos(Φ) Watts, (W)
