IamMeter

IAMMETER provides both a bi-directional single-phase energy meter(WEM3080) and a bi-directional three-phase energy monitor (WEM3080T). Both of them can be integrated into Home Assistant. The WEM3050T is the latest three-phase/split-phase meter, released by IAMMETER on Nov 2023. The WEM3050T provides nearly all of the features the WEM3080T provides, with the exception of the cloud service. The WEM3050T can be integrated into Home Assistant by all of the methods that WEM3080T supports. Because there is no cloud service by default, the WEM3050T is much cheaper than the WEM3080T.

Configuration

To use this integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] in your installation, add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file. After changing the configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file.
