What may cause error Platform not found: sensor.ping?

Question

I am trying to setup a binary icmp sensor to see when my TV is on or off.

I have added this to my configuration.yaml

# Sensors
sensor:
 #TCL 
 - platform: ping
   host: 192.168.0.1

and I am getting the following error when I try to check the config:

Configuration invalid
Platform not found: sensor.ping

Version:0.84.6 (HASS.io)

Am I missing something obvious?

Answer 1

Silly me!

It is a binary sensor so it should be:

binary_sensor:
#TCL 
  - platform: ping
    host: 192.168.0.1

Answer 2

Binary sensor AND:

device_tracker:
  - platform: ping
    hosts:
      xi_readmi7a_name_ping: 192.168.1.43
      ...

Platform: ping allows you to create both a binary sensor (on/off) and a device_tracker (home/not_home). Accordingly, device_tracker can be added for stationary location of the user ...
