Grid State

[leodale]

Hello,
I would ask if its possibile to integrate a "Status Flag" where i can ask the inverter if the Grid is on or off so that i can control other things when the grid became off. (For example turn off big loads when grid goes off and backup on the inverter goes on)

I have found on internet that the inverter have a Register: 13030 Grid State.
I have included to the configuration yaml this, but it dosnt work, it returns a value: "65535"

  - name: Grid state
        unique_id: sg_grid_state
        slave: !secret sungrow_modbus_slave
        address: 13029 # reg 13030
        input_type: input
        count: 1
        data_type: uint16
        scan_interval: 10

Can anybody help me ?
Thank you
Leonardo

Take a look at sg_inverter_state. Will tell you the current inverter state. If grid fails, the state changes to Off-grid mode. Or you use sensor.system_state` and decode it yourself. Mayne as a binary sensor. You will find the values for the different states in the yaml beginning with line 1946.

Thank you! I tried to set up a new automation so that I can activate a scene to turn off big loads in case of "Black out".
If i have correctly unterstand so
the value off sensor.system_state "64" is Running, and "4096" ist Off Grid.
I became the following error when i try to add an automation (numeric state):
Response error: 500

This is my automation
`description: ""
mode: single
trigger:

• platform: numeric_state
  entity_id: sensor.system_state
  attribute: "4096"
  above: 4095
  below: 4097
  condition: []
  action:
• service: scene.turn_on
  target:
  entity_id: scene.not_betrieb
  metadata: {}
  alias: Neue Automatisierung`

I have implemented the automation manually in the automation.yaml. Now the problem is the following. When i simulate a black out (turn off the Grid) the value from inverter state is "256" = Fault. But it should be 4096 = Off Grid.
Why the inverter goes "Fault" ?
