"Platform" is not a valid option for a template binary sensor (ping)?

Until now, I’ve been doing network pings through Node-RED exclusively. I was playing around with setting up some binary sensors in my templates.yaml file (referenced from configuration.yaml) and this is causing problems:

# Network ping sensors
  - binary_sensor:
    - unique_id: upstairs_mesh_node
      name: Mesh Node
      platform: ping
      count: 5
      scan_interval: 600

I get this error on checking config:

Logger: homeassistant.config
Source: config.py:916
First occurred: 8:31:55 AM (7 occurrences)
Last logged: 8:42:42 AM

Invalid config for [template]: [platform] is an invalid option for [template]. Check: template->binary_sensor->0->platform. (See /config/templates.yaml, line 659).

The sensor syntax, spacing and everything is identical to my other sensors. Any ideas?

You got that error because you added a Ping Binary Sensor into a file reserved for the configuration of Template entities.

That’s what this line in your configuration.yaml file means:

template: !include templates.yaml
Template entities 

Move the Ping Binary Sensor out of the templates.yaml file.

Oof, thank you. I’ve made this error before and forgot what I learned. I’ve placed it in a new file, binary_sensors.yaml.

You’re welcome!
