Lost binary_sensor !?!

Weird but from some point of time I see an error in log

2020-10-06 20:56:24 WARNING (MainThread) [homeassistant.helpers.entity_component] 
Forced update failed. Entity binary_sensor.is_amazon_tvstick_on not found.

the sensor is configured in configuration.yaml

  - platform: command_line
    name: 'is_Amazon_TVStick_on'
    command: 'ping -c 2 -W 2 192.168.222.66 | grep "2 packets received" | wc -l'
    device_class: connectivity
    scan_interval: 60
    payload_on: 1
    payload_off: 0

But what is more interested the system creates a second instance of the sensor and its status keeps updating while the original sensor is not getting any update.

How can I fix this all?

Why not just use a ping device tracker?

… or a ping binary sensor.

Ok, Iv replaced config. WIll monitor it…
