Simplified API Calls

The following settings can now be configured directly on the web page, eliminating the need to manually call the API:

  • Enable NEM mode (Net Energy Metering mode).
  • Enable Reactive Power Measurement (kvar, kvarh).
  • Set the CTC Ratio (primarily used in split-phase systems, allowing a three-phase meter to monitor both split-phase inverters and grids simultaneously. For details, refer to Monitor the system of 120/240V or 120/208V in North America and Understand the parameter of CTCratio).
  • Configure the upload interval, with a minimum setting of 1 second.
    • Note: This upload interval applies only to modes other than IAMMETER-cloud. When using IAMMETER-cloud, the upload interval is fixed at 1 minute.

Support for MQTT Discovery in Home Assistant

Watch Video: Enable MQTT Discovery for Home Assistant in IAMMETER's Energy Meter

With the following settings, IAMMETER's energy meters can be automatically discovered in Home Assistant:

  1. Run Mode: Select "MQTT."
  2. Address: Enter the MQTT broker's address and port.
  3. Username/Password: Provide the MQTT broker's username and password.
  4. HA MQTT Discovery: Check this option to enable data publishing in the MQTT discovery format required by Home Assistant (topic and data format).
  5. Upload Interval: Set the data upload interval (e.g., 1 second means the meter uploads data to the MQTT broker every second).
    • Caution: Setting a very short interval may increase the likelihood of firmware upgrade failures. It is recommended to set this parameter to 1 minute during firmware upgrades.
