Energy monitor(three phase energy meter Wi-Fi,single-phase energy meter Wi-Fi) in Home Assistant
premise:Which type of electrical meter best fits your needs?
This article will show you how to integrate the Wi-Fi energy meter (both single phase and 3 phase) into the home assistant, by the core integration. If you are more interested in other ways (Modbus/TCP, MQTT, or HACS), please refer to this article first.
Summary:how to use IAMMETER`s Wi-Fi energy meter in the Home assistant
If you want to integrate the Wi-Fi energy meter (IAMMETER) into Home assistant, there are three options now.
| No. | Products | Description |
|---|---|---|
| 1 |  |
WEM3080T : three phase wifi energy meter |
| 2 |  |
WEM3080 : single phase wifi energy meter |
Home Assistant (https://www.home-assistant.io/) is an open source home automation system.
IAMMETER WiFi energy meter can be integrated with Home Assistant system.
Introduction in Home Assistant https://www.home-assistant.io/integrations/iammeter/
This is a simple demo of integrating the bi-directional Wi-Fi Energy meter to Home-Assistant system,

You can remotely switch ON/OFF the three lights and see how the power changes accordingly.
Install the latest version of Home Assistant (0.107.0.dev20200310 or later version)
To use the Iammeter sensors in your installation, add the following to your configuration.yaml file:
# Example configuration.yaml entry
sensor:
- platform: iammeter
host: 192.168.1.6
name: meter
Tips: You can find your meter and check its host IP address by double clicking its icon in the network of your PC which is connected to the same home Wi-Fi network
Restart the server management and reconnect to it, then you will see the entity of the meter if the meter is already connected to the Internet.

Here you can add the card manually
Or you can copy and paste the following code
cards:
- cards:
- entity: sensor.meter_voltage
max: 300
min: 100
name: voltage
theme: default
type: gauge
- entity: sensor.meter_power
max: 5000
min: 0
name: power
theme: default
type: gauge
type: horizontal-stack
- entities:
- entity: sensor.meter_voltage
name: voltage
- entity: sensor.meter_power
name: power
- entity: sensor.meter_importenergy

- entity: sensor.meter_power
- entity: sensor.meter_voltage
- entity: sensor.meter_importenergy
hours_to_show: 24

Save and then you will see the meter's data.
Compared with the IAMMETER integration in the home assistant, you can also try to use the Modbus/TCP sensor in the home assistant to request the data of the IAMMETER`s energy meter.
The most advantage of the Modbus/TCP sensor in Home Assistant is it can request the data faster, up to 1s/s(sample/second). Because of the faster sample rate, it can be used as a real-time sensor feedback value in a control loop.

We provide an IAMMETER-simulater that will help the user to evaluate IAMMETER`s product before ordering it. It can simulate the solar PV output, loads profile, and an EV charger with a specific battery capacity. It also supports the same API as WEM3080T so that you can integrate it into the Home assistant with the same method as WEM3080T. After you confirm that this meets your requirements, you can purchase real hardware. The replacement (IAMMETER-Simulator->real energy meter)is also easy, only need to do the following two steps. 1 install the energy meter in your system. 2 replace the IP in the HA from the IAMMETER-simulator to your real hardware.
