Question about validation code esp32

ESPHome

I am trying to set ESPHome to work directly with Node-red to monitor some relays…

Is this mqtt code OK for the relay to include?

>     name: "Relay 1"
>     id: relay_1
>     pin:
>       pca9554: expander_hub
>       number: 0

>       state_topic:   "stat/8ro/relay1"      # custom state topic
>       state_on: "ON"
>       state_off: "OFF"
>       retain: true                          # ensure state is retained

^^ How / Where can I get the information documents for configuration?

I am using this device:

>   board: esp32-s3-devkitc-1
>   variant: esp32s3
>   flash_size: 16MB

^^ It doesn’t like the mqtt code under the relays and can’t validate.

No. From where you got that code in the first place? Esphome documentation doesn’t lead to that for sure and even AI doesn’t output code like that.
