Enphase Envoy

An integration for the Enphase Envoy solar energy gateway. This integration works with older models that only have production metrics (ie. Envoy-C) and newer models that offer both production and consumption metrics (ie. Envoy-S). Firmware version 3.9 or newer is required.


To add the Enphase Envoy integration to your Home Assistant instance, use this My button:

Enphase Envoy can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.


This integration will offer various sensors depending on the configuration of your Enphase system. Sensors are available for the following:

  • Current energy production & consumption
  • Historical energy production & consumption
  • Power production per-inverter

Consumption sensors require your Envoy to be properly configured with consumption CT sensors installed.

For Envoy S Metered / IQ Gateway Metered with installed and configured current transformers (CT), additional features are available:

  • Sensors for net production (grid export) and net consumption (grid import) if the consumption CT is a net-consumption CT.

  • Disabled sensors for:

    • Production and consumption sensors for each phase, if CT are installed on more than 1 phase.
    • Phase net production and net consumption, if CT are installed on more than 1 phase.
    • Frequency net consumption CT (aggregate and phase).
    • Voltage net consumption CT (aggregate and phase).1
    • Metering status for net consumption and production CT (normal | not-metering | check-wiring) (aggregate and phase).
    • Meter status flags active for net consumption and production CT (aggregate and phase).2

For Enphase Ensemble systems with the Enpower/IQ System Controller and Encharge/IQ Batteries installed, additional features are available:

  • Sensors for battery status and usage
  • Sensors for grid status
  • Sensors for the state of the Enpower’s 4 load-shedding relays
  • A switch allowing you to take your system on-grid and off-grid. Note that the Enpower has a slight delay built-in between receiving these commands and actually switching the system on or off grid.
  • A switch allowing you to enable or disable charging the Encharge/IQ Batteries from the power grid.
  • Support for changing the battery storage mode between full backup, self-consumption, and savings mode and setting the reserve battery level for outages.
  • If a storage CT is installed:
    • Sensors for battery storage energy charged and discharged and current active power discharge/charge
    • Disabled sensors for:
      • Phase battery storage energy charged and discharged and current power discharge/charge
      • Voltage net consumption CT (aggregate and phase)
      • Metering status for storage CT (aggregate and phase)
      • Meter status flags active storage CT (aggregate and phase)

Envoy authentication requirements

For newer models running firmware 7 and greater, you will need your Enlighten cloud username and password. The integration will use these credentials to obtain an Envoy access token from the Enlighten cloud.

For models running firmware 5 and older, use installer for the username. No password is required. The integration will automatically detect the installer password.

Enpower load shedding relays

The Enphase Enpower has 4 load shedding relays that can be used to control non-essential loads in your home. These have two main modes of operation:


When the mode entity is set to standard, you can simply set the state of the relay to be powered or not powered for each mode of operation: on grid, off grid, and on generator.

Battery level

When the relay mode is set to battery level, the relays will turn on and off based on the remaining battery level of your Encharge batteries. Two number entities are available to control the cutoff and restore levels for the relays. When the battery level drops below the cutoff level, the relays will turn off. When the battery level rises above the restore level, the relays will turn back on.

Polling interval

The default polling interval is 60 seconds. To customize the polling interval, refer to defining a custom polling interval. Specify one single entity from the envoy device as target of the service using the + choose entity button. Updating one entity will update all entities of the Envoy and the related devices like the inverters; there is no need to specify multiple or all entities or add (all) inverter entities. When using multiple Envoys, add one entity for each envoy as targets or create separate custom polling intervals with a single entity as needed.

Credentials or device IP address update

This integration supports updating the Envoy configuration through a reconfigure menu option. The reconfiguration allows for changing the Envoy IP address, username, and/or password. Use this menu option if your Enlighten credentials or the device’s IP address has changed and needs to be manually updated. The latter is typically automatically detected and updated.

Use this menu option also when an Envoy firmware upgrade requires a switch from local Envoy username/password to token-based authentication with Enlighten username/password (refer to authentication requirements).

Energy dashboard

This integration provides several values suitable for the energy dashboard:

  • For Solar production, use the Envoy Lifetime energy production entity.
  • For Grid consumption, use the Envoy Lifetime net energy consumption entity.3
  • For Return to grid, use the Envoy Lifetime net energy production entity.3
  • For Energy going into the battery, use the the Envoy Lifetime battery energy charged entity.4
  • For Energy coming out off the battery, use the the Envoy Lifetime battery energy discharged entity.4

Debug logs and diagnostics

This integration provides debug logs and diagnostics reports as described in the Home Assistant troubleshooting pages.

Debug log

When experiencing issues during the use of the integration, enable the debug log for the Envoy / IQ Gateway. This will add details on the data collection to the Home Assistant log file. Leave the debug log enabled long enough to capture the occurrence of the issue. If the issue is intermittent, this may take a while and it may grow the log file quite a bit.

If you’re expecting features to show but they are not shown, reload the integration while debug logging is enabled. When this integration is loaded, it will scan the Envoy / IQ Gateway for available features and configure these as needed. Following this initial scan, only data for the found features is collected. Performing a reload with debug enabled results in the debug log containing the initial full scan to assist with analyzing any missing features. Some features are disabled by default, and you need to enable them if you want them to show. Verify this before starting a debug session.

The debug log will show all communication with the Envoy / IQ Gateway. Lines starting with entities are log entries for the integration:

2024-03-07 11:20:11.897 DEBUG (MainThread) [homeassistant.components.enphase_envoy
2024-03-07 11:20:11.898 DEBUG (MainThread) [pyenphase.envoy

Below a typical data request / reply sequence in the log file. These lines will contain the data details received from the Envoy / IQ Gateway.

... [pyenphase.envoy] Requesting with timeout ...
... [pyenphase.envoy] Request reply from status 200:...

The end of a collection cycle is marked by:

... [homeassistant.components.enphase_envoy.coordinator] Finished fetching Envoy 123456 data in 1.234 seconds (success: True)


The diagnostics file is a JSON file and includes a data section with the details for this integration. The file can be viewed with any text editor5. The data section has 5 major subsections which reflects how the integration is setup and data is used. Below the 5 subsections, each collapsed.

  "data": {
    "config_entry": { ...
    "envoy_properties": { ...
    "raw_data": { ...
    "envoy_model_data": { ...
    "envoy_entities_by_device": [ ...

Config entry

Shows the integration configuration created when the integration was added.

Envoy properties

Shows the conclusions of the initial data scan and what features were identified, including the detected firmware version in the Envoy.

Raw data

Shows the data collected from the Envoy during the last data scan when the diagnostic report was created. If in doubt about data shown in the dashboards, consult this section to find the raw data sent by the Envoy. The integration is not modifying this data, it’s just providing the data to the entities.

Envoy model data

Shows the data of the Envoy extracted from the raw_data into Envoy class data used by the Home Assistant integration. This is a subset of the full raw dataset.

Envoy entities by device

Shows all entities created by the integration based on the findings of the initial scan, grouped by device. Entity state based on the last data collection cycle is included. State values here come from the Envoy model data and are the values visible in the dashboards.

  1. For multi-phase systems, the Envoy sums the voltages of the phases. May be valid for split-phase, but for 3-phase systems use the individual phases rather than the summed value.

  2. If this value is non-zero, consult the diagnostic report of the Envoy and look for raw_data - /ivp/meters - statusFlags for set flags (production-imbalance | negative-production | power-on-unused-phase | negative-total-consumption).

  3. Only applies when using Envoy S Metered / IQ Gateway Metered with installed and configured CT.

  4. Only applies when using Envoy S Metered / IQ Gateway Metered / IQ Combiner with installed and configured storage / battery CT.

  5. Use of a JSON-aware viewer is not required but makes inspecting the file easier.
