Recent Releases of huawei_solar

huawei_solar - 1.5.4

Fixes 🐛

  • Force pyModbus version to "<3.8.5", as it contains a regression that breaks all communication with devices with slave-id 0 (cfr. #940)

Thank you! 💖

A big thank you to all my sponsors! Your support helps to keep this integration in great shape.

huawei_solar - 1.5.3

Improvements 🚀

This release adds:

  • support for Huawei EMMA devices (unstable)
  • auto-discovery of devices during initial setup, making it unnecessary to lookup the Modbus Slave ID's of each device.
  • Sensors for temperatures of individual battery packs (by @TomHarm in #830)
  • MPPT scan interval is now configurable (by @TomHarm in #830)

Fixes 🐛

Dependency upgrades 📦

This integration relies on the Python library 'pyModbus' to communicate with your Huawei Solar installation via the Modbus protocol. Other integrations, like the native modbus-integration of Home Assistant do the same. Recently, the pyModbus project released a series of releases containing breaking changes. When this integration is used in conjunction with other integrations which rely on an incompatible version, this breaks your installation as only one version of pyModbus can be installed at any one time. This led to issues in HA2025.1 (cfr. issue #873).

This release upgrades the pyModbus version used to v3.8.3, which is in line with the version used by the native modbus-integration of HA 2025.2, restoring compatibility.

[!NOTE]
If you use other (custom) integrations which rely on incompatible pyModbus versions, then these compatibility problems will persist until the other integration also upgrades their pyModbus dependency. Please contact the author of that integration if that is the case.

huawei_solar - 1.5.0 beta 2

Improvements 🚀

This release adds:

  • support for Huawei EMMA devices (unstable)
  • auto-discovery of devices during initial setup, making it unnecessary to lookup the Modbus Slave ID's of each device.

Fixes 🐛

Dependency upgrades 📦

This integration aims to use a compatible pyModbus version which allows it to be used together with the native modbus-integration of Home Assistant. As of HA 2025.1, Home Assistant was upgraded to use pyModbus v3.7.2 instead of v3.6.9, which had breaking changes. This is causing issues for users which use this integration alongside that native modbus-integration: https://github.com/wlcrs/huawei_solar/issues/873.

As the pyModbus project has already released v3.8.2, which once again has breaking changes, this integration was upgraded to use that latest version. At the time of writing these release notes, a PR already exists against HA core to upgrade pyModbus there from v3.7.2 to v3.8.2, bringing everything back into sync.

Note: if you use other (custom) integrations which rely on incompatible pyModbus versions, then you can expect compatibility problems. Please contact the author of that integration and ask him to upgrade the pyModbus version used.

⚠️ Alpha release: expect that things can be broken ⚠️

Please report any unexpected behavior via an Issue. I'm particularly expecting issues regarding to changing inverter and battery configuration parameters when connected via an EMMA device. Please check if you are using the latest EMMA firmware version, and properly document how you connect to the EMMA in your issue.

huawei_solar - 1.4.0

This release is a large overhaul to further improve the efficiency of the integration, made possible by improvements in Home Assistant.

Most notably, the integration can now dynamically compute which registers must be queried from the inverter, depending if they are enabled or disabled in HA.

This has also made it possible to add more entities to the integration. While they have all been disabled by default for performance reasons/because they provide (almost) duplicate information, they might be of interest to some users.

Furthermore, the update cycle of inverter, power meter and battery entities have now been separated into three separate parts. This allows you to raise the update interval for only one of those three parts instead of all entities. This will be particularly useful for people wanting to update power meter values at high speed.

⚠️ If you have changed the polling frequency in the past, you will need to duplicate this into three separate automations now ⚠️

This release has been tested by 200 users for an extended time as an alpha-version. Thank you for testing! 🎉

Improvements 🚀

  • Add inverter active power derating entities (#683)
  • Add forcible charge status sensor (#731)
  • Add reconfigure flow (#689)
  • Add insulation resistance sensor (#727)

Fixes 🐛

  • Fix detection logic for power meters (#671)
  • Fix device_class and state_class of battery (dis)charge entities (#684)

huawei_solar - 1.1.0

New recommended connection option: direct serial RS485

This release features adds support for direct serial connection via the RS485A1 and RS485B1 pins of the COM-port of the SUN2000-inverter. This is the new preferred method of connecting to the inverter, as it is not susceptible to network connectivity issues, and has elevated permissions by default (necessary for retrieving optimizer data and setting battery configuration parameters).

New feature: reading optimizer data

This data is refreshed every 5 minutes, as the inverter does not offer more granular updates.

Exposed entities:

  • Input Current
  • Input Voltage
  • Output Current
  • Output Voltage
  • Output Power
  • Temperature

The option "Advanced: elevate permissions" needs to be checked for this to work: the inverter requires elevated permissions to request the optimizer data.

Tip: the easiest way to find the Optimizer "devices" in Home Assistant is via:

  • Go to Settings > "Devices & Services"
  • click on "X devices" in the "Huawei Solar" tile

Clicking on a specific optimizer will show you the entities associated with that specific optimizer. You can now rename them to something more clear for your setup.
