This article introduces an addition to IAMMETER’s ecosystem—a Tasmota-based smart plug that supports MQTT and provides real-time electrical data. The smart plug has been pre-flashed with the open-source Tasmota firmware and configured for seamless MQTT integration, making it an ideal companion for energy monitoring enthusiasts, especially those already using platforms like Home Assistant, Node-RED, or their own MQTT-based logging solutions.

The smart plug is capable of reporting key electrical parameters, including voltage, current, active power (W), power factor, and accumulated energy consumption (kWh). It publishes telemetry data to the tele/ MQTT topic and responds to control commands via the cmnd/ topic. With this setup, users can monitor the power usage of individual appliances in real time, perform automation based on load, or analyze standby power drain.

IAMMETER has also shared how this smart plug can be used in conjunction with their three-phase energy meters (like the WEM3080T) for more granular device-level monitoring. This is particularly useful for users who want to complement whole-house monitoring with per-outlet insights.

As part of a limited-time promotion, IAMMETER is offering this smart plug as a free gift to select customers who place new orders, and to contributors who actively share their system integrations, use cases, or tutorials involving IAMMETER products in online communities.

This initiative not only encourages community engagement but also empowers users to build more comprehensive and open-source-friendly energy monitoring systems based on MQTT, Tasmota, and IAMMETER.
