How to determine command_line switch state

Configuration
1

I can get the status of a switch using curl

 curl -X GET https://us.wio.seeed.io/v1/node/GroveRelayD1/onoff_status?access_token=xxxxxxx

This returns json of either:

{ "onoff": "0" }

or

{ "onoff": "1" }

How do I use command_state in the command_line switch

What I’ve tried

switch:
  platform: command_line
  switches:
    port_1_wiolink_1_d0:
      command_on: "/usr/bin/curl -X POST https://us.wio.seeed.io/v1/node/GroveRelayD0/onoff/1?access_token=xxx"
      command_off: "/usr/bin/curl -X POST https://us.wio.seeed.io/v1/node/GroveRelayD0/onoff/0?access_token=xxx"
      command_state: "/usr/bin/curl -X GET https://us.wio.seeed.io/v1/node/GroveRelayD0/onoff_status?access_token=xxx"
      value_template: '{{ onoff == "1" }}'

Also

switch:
  platform: command_line
  switches:
    port_1_wiolink_1_d0:
      command_on: "/usr/bin/curl -X POST https://us.wio.seeed.io/v1/node/GroveRelayD0/onoff/1?access_token=xxx"
      command_off: "/usr/bin/curl -X POST https://us.wio.seeed.io/v1/node/GroveRelayD0/onoff/0?access_token=xxx"
      command_state: "/usr/bin/curl -X GET https://us.wio.seeed.io/v1/node/GroveRelayD0/onoff_status?access_token=xxx"
      value_template: '{{ value_json.onoff == "1"  }}'

Yet I find when I restart home assistant, it always shows the switches as being off.

How do I use value_template ?
How often does home assistant poll the switch to find its state?

The following works

value_template: '{{ value_json.onoff == 1 }}'

As for when the state is polled, It is polled shortly after a service restart.
It also seems to poll every minute or two.
