Subscribing the instant value of the Energy meter
Subscribing the real time power value of the Energy meter
This article is a summary, mainly for customers who want to do the second development.
It lists different methods that can subscribe the energy data from systems or WiFi energy meter .
Welcome to discuss with us here https://imeter.club/topic/445
Subscribing the data from IAMMETER-cloud
IAMMETER-cloud can return the instant reading by an API. The user can create a token in the account and read the instant value(voltage, current,active power,forward kWh, and reverse kWh) by the API with this token.
For more details ,please refer to HTTP API of IAMMETER
IAMMETER-cloud also provide the MQTT broker for testing(not a standard service). So you can also subscribe the instant value from IAMMETER-cloud by MQTT.

new feature: Develop your own web monitoring view
Subscribe topic from IAMMETER by Home Assistant
Subscribing the data from IAMMETER-Docker
IAMMETER Docker is an simple version energy monitoring system, deployed by IAMMETER. Its key features are:
- it can be deployed in customer`s own server (recommend to use Raspberry PI as your server).
- Running as API server, you can design and develop your own UI by open API.
IAMMETER-docker provides MQTT broker inside. So you can subscribe the instant data by mqtt . Please refer to https://www.iammeter.com/docs/docker-advanced#subscribe
For more introduction about IAMMETER-docker ,please refer to Introduction about IAMMETER-Docker
Subscribing the data from a MQTT broker
IAMMETER`s product supports MQTT protocol, it can be configured to publish data via MQTT. If you have an MQTT broker, you can configure the energy meter to publish data directly to it, then you would be able to subscribe the data from your own mqtt broker.
More details ,please refer to
Read the data directly from the energy meter
The above chapters show you how to integrate the energy meter into different systems and then subscribe the data. This chapter will show you how to read the data directly from the hardware directly. Both single-phase energy meter and three-phase energy meter support flexible data interfaces.
Method: http get
Method: http get
Modbus TCP is common protocol that used in industrial system such as ICS, DCS, SCADA.
Both WEM3080T(3 phase energy meter ,Wi-Fi) and WEM3080 (single phase energy meter, Wi-Fi) have supported Modbus/TCP now.
In this mode, it supports data inquiry in 1s/s.This is the biggest advantage of this mode.
Support Modbus/TCP in the Wi-Fi energy meter of IAMMETER
Read the data from Home assistant and NodeRed
If you are familiar with some open-source platforms, such as home assistant, NodeRed. It will also be easy to integrate the WiFi Energy meter in them and then subscribe the data.
