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.

1.0.2

Bump huawei-solar library to v2.0.2, which fixes the re-login flow after an interruption of the initial session.

1.0.1

Update to huawei-solar 2.0.1:

• Add resilience against permission loss due to connectivity issues
• Recognize invalid register values and return None instead

v1.0.0

This release uses the new 'HuaweiSolarBridge' which moves a lot of the complexity into the huawei-solar library.

It also contains support for changing settings, all of which are related to use of battery storage.

.

v1.0.0 alpha 4

• Add battery running status (#34)
• Fix battery detection logic (#35)

v1.0.0 alpha 3

This release uses the new 'HuaweiSolarBridge' which moves a lot of the complexity into the huawei-solar library.

It also contains support for changing settings, all of which are related to use of battery storage.

Fixes in 1.0.0 alpha 3:

• Remove dysfunctional second Grid Active Power-entity from single power meter entities
• Improve handling of Slave Busy exception
• prevent multiple slaves running update at the same time
• Increase cooldown-time between requests from 0.01 to 0.05 seconds.

v0.5.1

This release contains initial support for bundled modbus-requests: adjacent modbus registers are queried together with one request, instead of being queried one by one.
