huawei_solar - 1.5.7 beta 1

The only difference between this beta and the 1.5.7 release is that this beta has been marked to support HA2025.09.b0 .

[!WARNING] This release is INCOMPATIBLE with HA 2025.08 and earlier This release is REQUIRED for HA 2025.09 and later

This integration communicates with the Huawei inverters using the Modbus protocol. To achieve this, we use the popular pyModbus library. Sadly, the maintainer of this library frequently releases new versions which are slightly incompatible with each other, leading to stuff breaking all over the place for Home Assistant. As a stop-gap solution, Home Assistant is now pinning its monthly releases to a specific pyModbus version. As long as this integration keeps using pyModbus, this integration will need to tightly follow the pinned versions by Home Assistant. Every time Home Assistant changes the pinned pyModbus-version, you will need to upgrade this integration at exactly the moment you do your monthly HA upgrade.

I'm working on an alternative solution, but don't expect it to be ready for prime-time until the end of the year.

huawei_solar - 1.5.6

This is an emergency release because of compatibility issues with the native HA modbus integration in HA2025.08.2 which prevent this integration from loading.

Some background: both this integration and the native modbus integration use the same underlying Python library called "pyModbus". The maintainer of said library frequently makes small changes to the API, leading to subtly incompatible versions being released every few months. This release relaxes the version requirements of the pyModbus library so that it can be combined with a fixed version requirement set by the native modbus integration in 2025.08.2 .

Please be aware that breakage is already guaranteed when HA2025.9 will be released, as the pyModbus library maintainer has changed a parameter name affecting almost every function call without any backward compatibility. I will release a new version around the release day of HA2025.9

Keeping up with the frequent pyModbus API changes is a very tiring game of playing cat and mouse where little is gained. Sadly, there is currently no other Python library which is powerful enough to implement all the Huawei-specific calls. I'm considering creating my own Modbus library instead, but this will take time to get to a sufficiently stable and mature state. Hopefully something that will be ready for general usage by the end of the year.

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 🐛

• Fix serial connection (was broken in v1.5.0 and v1.5.1, cfr: #901)
• Update of some device_class and entity_class values to remove warnings in logs (by @peetersch in #817)
• fix unit of reactive power (by @mpw96 in https://github.com/wlcrs/huawei_solar/pull/804)
• Fix writing TOU registers (cfr. https://github.com/wlcrs/huawei_solar/issues/877 )
• Fix support for Huawei-inverters that were rebadged by EDF (cfr. #902) and other brands (was broken in v1.5.2, cfr. #906)

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.

• Fix writing TOU registers (cfr. https://github.com/wlcrs/huawei_solar/issues/877 )

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.

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 deviceclass and stateclass of battery (dis)charge entities (#684)

huawei_solar - 1.2.0 beta 1

New ✨

This release upgrades the huawei-solar library from 2.1.6 to 2.2.0b2. The main difference between these library versions is that underlying pyModbus library has been upgraded from 2.5.3 to 3.0.2. This has allowed some cleanup in huawei-solar, and should hopefully fix some bugs present in pyModbus.

Thank you

A big thanks to all my current and past sponsors. Your contributions keep me motivated to maintain this integration to a high standard! ❤️

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 - Accumulated Energy Yield - Voltage to Ground (disabled by default) - Running Status (online/offline/disconnected)

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

You will now see a list of all devices associated with this integration, including one per optimizer:

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.
