RASPI 4 on UNIPI 1.1

Hello,

hope someone could help me.
My config looks like:

RPI4 on a UniPI 1.1
The Unipi 1.1 has a mcp23008 build in to controll 8 relay’s. I have try to configure with the module mcp23017 the unipi as switch.
I have looked in the dokumentation of the unipi. i2c_address ist 0x20

I2C is configured an seams to work.

My configuration.xml:

switch:
- platform: mcp23017
    i2c_address: 0x20
    pins:
       0: tuerlicht
       1: Gartenhaus
       2: Lischtschlauch
       3: Beetlampe
       4: Klingel
       5: test1
       6: test2
       7: test3
       8: test4

My problem is, if i hit on of the switch’s nothing happend.
What could i do? Could some help me?

thx
