SOLVED: Configuration problem with Modbus TCP

Configuration
1

I have an issue configuring modbus. This is my config:

modbus:
  - name: Pracht Alpha XT
    type: tcp
    host: alpha-xt.mylocal.domain
    port: 502
    sensors:
      - name: max_total_power
        address: 2
        unit_of_measurement: A

And this is in my logs:

2025-05-25 13:32:11.823 DEBUG (MainThread) [pymodbus.logging] Connecting to alpha-xt.mylocal.domain:502.

2025-05-25 13:32:11.957 DEBUG (MainThread) [pymodbus.logging] Frame advanced, resetting header!!

for me, it looks like it is working. But I do not get an entity created. What is missing?

Thanks

Ok, I got it. Had to restart my browser. For some reason old data was cached on some parts of the UI. Historical data was up to date, but current values not. Same for the list of entities. Strange.
