This logic group reads values from a Huawei SUN2000 inverter via the FusionSolar API.

A token is required to query the values via an http request. This token, which is necessary for the query, is queried with the http request element "getToken" and transferred to the actual http request elements that query the values.
The queried values are then sent to the KNX bus via four outputs.

To be able to use the API, an account for your installation is necessary!
Contact the service team at eu_inverter_support@huawei.com to create an "openAPI" account for your installation.

Insert these credentials into the http element "getToken".

In the http request, the login information is entered in the field "User data" (type JSON).
{
"userName": "XxXxXxxXxAPI",
"systemCode": "ZxZxxZxZxZ"
}

The following values are read out with this logic group and made available on the KNX bus:
- Active power (kW)
- Daily output (kWh)
- Monthly output (kWh)
- Total output (kWh)

Further values are available via the API interface.
