Connect Home Assistant Energy Devices to IAMMETER Cloud
Introduction
If your meter, inverter, or other energy device is already connected to Home Assistant, you can now reuse that data in IAMMETER Cloud without adding another physical meter first.
The new HACS integration IAMMETER-Link is built for exactly this scenario. It sends sensor data from Home Assistant to an IAMMETER Virtual Meter, where the data can then be displayed and analyzed in IAMMETER Cloud.
For users who already treat Home Assistant as their central data hub, this is a practical way to extend existing integrations into IAMMETER Cloud for visualization, energy analysis, and solar monitoring.
What IAMMETER-Link Does
IAMMETER-Link works as a bridge between Home Assistant and IAMMETER Cloud.
It does not read data directly from an IAMMETER hardware meter. Instead, it takes existing sensor entities from Home Assistant and uploads their values to a Virtual Meter in IAMMETER Cloud.
This brings several practical benefits:
- reuse existing meter or inverter data already available in Home Assistant
- avoid deploying another separate data collection path
- use IAMMETER Cloud for visualization and further energy analysis
Typical supported values include:
- voltage
- current
- active power
- energy in kWh
If your Home Assistant setup already exposes these values, it can be used as the source for IAMMETER-Link.
Prerequisites
Before adding the integration, make sure the following conditions are met:
- You need an IAMMETER Cloud account. If you do not have one yet, that is not a blocker. IAMMETER-Link can help you register an IAMMETER Cloud account in the first step of the setup flow.
- Home Assistant already has usable energy-related sensor entities.
- The source device provides the key values required for your scenario, such as voltage, current, power, and energy.
Once the account is ready, you can use the Virtual Meter provided by IAMMETER Cloud during setup.
If your goal is solar monitoring, it is also worth reviewing IAMMETER's solar PV monitoring solution to understand how this integration fits into the broader workflow.
Install IAMMETER-Link from HACS
The setup starts in HACS.
Install IAMMETER-Link in HACS, then go to:
Settings -> Devices & services
Add the IAMMETER-Link integration and start the configuration flow.
Sign In to IAMMETER Cloud
During configuration, the integration asks for your IAMMETER Cloud username and password.
If you do not have an IAMMETER Cloud account yet, you can also complete registration directly in this setup step.
If your account has already applied for a Virtual Meter, the integration will usually ask whether you want to reuse the existing Virtual Meter SN or request a new one. In practice, most users should simply reuse the existing Virtual Meter, because one account normally has one free Virtual Meter available.
Choose Single-Phase or Three-Phase
Next, choose whether the data source is single-phase or three-phase.
For a three-phase scenario, you also need to define the role of each phase. This affects how IAMMETER Cloud interprets and displays the uploaded data.
Map Home Assistant Sensors
After the phase type is confirmed, map the Home Assistant sensor entities to the required IAMMETER fields for Phase A, B, and C.
Not every field is required. Any unmapped field is uploaded as 0.
There is one practical limitation to keep in mind:
If a sensor is mapped but its value cannot be read correctly at runtime, the upload process stops.
So the safer approach is to map only sensors that you have already verified as stable and valid in Home Assistant.
If you want to use this integration for IAMMETER Cloud solar monitoring, the minimum recommended values are:
- power
- imported energy
- exported energy
These are the most useful values for solar-related analysis.
View the Data in IAMMETER Cloud
Once the configuration is complete, the Home Assistant sensor data is uploaded to IAMMETER Cloud through the Virtual Meter.
You can then view the data in IAMMETER Cloud and continue with energy analysis, home energy monitoring, or solar monitoring workflows.
Why This Integration Matters
For users who already use Home Assistant as a universal integration layer, IAMMETER-Link is more than just another upload path.
Its real value is this:
If any brand of inverter, meter, or other energy device is already connected to Home Assistant, then from the IAMMETER Cloud perspective, it can now also be connected to IAMMETER Cloud through IAMMETER-Link.
In other words, IAMMETER-Link allows IAMMETER Cloud to use Home Assistant as a compatibility bridge. The data source is no longer limited to IAMMETER hardware meters only. It can also come indirectly from the many devices that Home Assistant has already integrated.
That means you can combine:
- Home Assistant automation
- IAMMETER Cloud visualization
- energy analysis focused on optimizing usage and reducing electricity bills
One typical example is this:
You may already own an IAMMETER three-phase meter to monitor the three-phase grid. Later, you may also want to monitor a three-phase inverter. Previously, that often meant buying another three-phase meter to bring the inverter into the IAMMETER monitoring system.
Now, if the inverter is already connected to Home Assistant, IAMMETER-Link can send the inverter data directly to IAMMETER Cloud. This means both grid-side data and inverter-side data can be monitored together in IAMMETER's solar PV monitoring solution.
If you are also interested in Home Assistant based solar automation, you can further review IAMMETER's Home Assistant solar automation solution.
Conclusion
If your meter, inverter, or other energy device is already available in Home Assistant, IAMMETER-Link provides a direct way to bring that data into IAMMETER Cloud.
The workflow is straightforward:
- install IAMMETER-Link from HACS
- sign in to or register for IAMMETER Cloud
- choose single-phase or three-phase
- map the relevant sensors
- verify the uploaded data in IAMMETER Cloud
For users who want to extend existing Home Assistant energy data into IAMMETER Cloud, this is not only a new integration method. It also means IAMMETER Cloud can work with many more brands of inverters and meters through Home Assistant.
