How to monitor webhook events in HA logs?

Hi, I have programed ESP8266 in PIO and want to send messages using webhook.
Messages are received by HA but unreliable. How to look for events related to webhook? I was trying to listed to events using Tools-Events listen to: binary_sensor.ddwrt_watchdog_relay or ddwrt_watchdog_relay but nothing detected.
IoT and HA on different SUBs, this is the reason for local_only: false.
Thank you.

My esp logs show consistently this: Webhook Status Update Sent. Response Code: 200
Here is what HA reports:

And this is my sensor in configuration.yaml

  • trigger:
    - platform: webhook
    webhook_id: “ddwrt_watch_Xxxxxxx”
    allowed_methods:
    - POST
    local_only: false
    binary_sensor:
    - name: “DDWRT watchdog relay”
    unique_id: “ddwrt_watchdog_relay”
    device_class: power
    # Reads the incoming key directly, completely ignoring whitespace variations
    state: “{{ trigger.json.state | lower == ‘on’ }}”
