This is a summary article that includes two parts.
|integration method||interface||refresh period|
|1||Core integration||HTTP||1 min|
|2||Modbus/TCP sensor||Modbus/TCP||1 s|
|3||MQTT sensor||MQTT||12 s|
|4||HACS||HTTP or Modbus/TCP||1 min(http),1s(Modbus/TCP)|
This is the first integration method that IAMMETER supported and has already been merged into the core of Home Assistant.
IAMMETER energy meter @ Home Assistant
Because it is very hard to merge new code in Home assistant core now(or maybe we still have not found a proper method), so many new features can not be used directly (such as device discovery, energy management component etc).

This is the best options if you want to refresh the energy meter`s reading (up to 1s/s) quickly in the home assistant. The support of high sample rate makes it can be used as the sensor value in some control loop.

It is a very common mode that integrates the device into the Home Assistant by MQTT.
The Wi-Fi energy meter of IAMMETER supports the MQTT uploading, with user/PWD authentication mode.
Set the username and pwd of the MQTT ,connect the energy meter to the Home Assistant

Because it is difficult to upgrade the IAMMETER`s integration in the core of Home assistant now, we provide a custom component about IAMMETER in HACS.

This article provide two methods to display the dashboard, use the lovelace dashboard or use the energy management component.
Monitor your solar PV system in the home assistant
Because of the high sample rate (1s/s) that supported in the modbus/tcp integration mode, there are many interesting function can be achieved. This app note show how to read the active power of the energy meter each 1 second and use this value to control the relay in home assistant.
Do a realtime control loop in the home assistant,use the reading of modbus tcp sensor to control the sonoff output.
