The Latest firmware of IAMMETER`s products
Welcome to Test the Latest Firmware for IAMMETER Energy Meter i.76.057
- This is a test version, not the final release.
- All IAMMETER energy meters can upgrade to this firmware for testing.
Brand New UI Interface
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:
- Run Mode: Select "MQTT."
- Address: Enter the MQTT broker's address and port.
- Username/Password: Provide the MQTT broker's username and password.
- HA MQTT Discovery: Check this option to enable data publishing in the MQTT discovery format required by Home Assistant (topic and data format).
- Note: If this option is not checked, the meter will publish data in the original IAMMETER MQTT format. Refer to Publish the data of IAMMETER's energy meter to your MQTT broker for details.
- 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.
