Command Line switch/sensor & Curl error

DOESIT · January 9, 2018, 10:18am

Hello,

I just installed the image of Hassio on a raspberry, but when I created a switch with a command_line it tells me continually an error, here is the command used:

platform: command_line
name: Room temperature
command: “curl -s’ http: // IP: PORT / json.htm? type = devices & rid = 122 ‘| jq -r .result [].’ Data ‘| cut -d’ -f1”
unit_of_measurement: “° C”
scan_interval: 30

Do you have any idea where the problem will come from?

How about creating a scrape sensor and use it with a a template switch instead?

Thank you I did not know I will test

I do not understand how to use scrape sensors.
I would like to recover the value of a temperature sensor.

If I open the url "http://IP:PORT/json.htm?type=devices&rid=18"in chrome, here is the result:
{
“ActTime”: 1515506873,
“ServerTime”: “2018-01-09 15:07:53”,

“XOffset”: “341”,

}
]
“status”: “OK”,
“title”: “Devices”
}

I would like to recover the value of “Data” so “18.9 C”

Do you have an article or tutorial that explains how it works?
Thank you.

Ah if your URL returns JSON, you might be better off using the REST platform?

sensor:
  - platform: rest
    resource: http://IP:PORT/json.htm?type=devices&rid=18
    name: Room temperature
    value_template: '{{ value_json.Data }}'

Not played too much with JSON extraction so I think you’ll need to amend '{{ value_json.Data }}' as your Data is under result

DOESIT · January 9, 2018, 3:30pm

I was just trying this but without success it returns a null value:

Temperature Salon ° C

It does not indicate the temperature.

[

platform: rest
resource: http://IP:PORT/json.htm?type=devices&rid=18
name: Température Salon
value_template: ‘{{ value_json.Data }}’
unit_of_measurement: °C
]

Result in the Home Assistant “< >” :
sensor.temperature_salon unit_of_measurement: °C
friendly_name: Température Salon
icon: mdi:thermometer

lolouk44 · January 9, 2018, 3:58pm

yes, as I said it won’t work with just {{ value_json.Data }}, you jeed to adjust as Data is under result in the JSON tree…
not sure if it should be {{ value_json.result.Data }} or {{ value_json.result[Data] }} or different.

DOESIT · January 10, 2018, 10:39am

Thanks again for the help, I managed by writing:

value_template: ‘{{ value_json.result[0].Data }}’

lolouk44 · January 10, 2018, 10:41am

Thanks for confirming and providing the format, I’ll keep a note of this for when I pull json data in the future

@DOESIT Just out of curiosity, is this a Netatmo Thermostat?

If so, why not use the Netatmo Thermostat component? Why re-invent the wheel, ya know!

DOESIT · January 10, 2018, 8:16pm

Yes indeed, he is not here to reinvent the wheel, I simply took an example parmit multiple temperature sensors that I have at home.

It is a Netatmo themostat indeed, the others are cheap sensors.

lolouk44 · January 10, 2018, 11:17pm

Quick question, what do you use to receive the signal from the cheap sensors?

DOESIT · January 11, 2018, 8:12pm

I use a Rfxcom transceiver.

lolouk44 · January 11, 2018, 8:29pm

Thanks.i was hoping you’d say something else. I have one too but it’s a type 1 and doesn’t support that sensor (I realised that after I bought 6 of course)

DOESIT · January 11, 2018, 10:31pm

Ok, I do not know the other models but you have I think, check if there was no update to support this sensor?

lolouk44 · January 12, 2018, 5:09pm

Thanks but no. It’s one of the first ones and doesn’t support that sensor

DOESIT · January 16, 2018, 9:04pm

I have a new question!

So I manage to make the switch work, but I would like to get its status, because if I turn on my switch via my home automation, home-assistant doesn’t know it, so use the "command_state"option.

Here is the command I use to get the status of the switch:“command_state:’ /usr/bin/curl -s “http://IP:PORT/json.htm?type=devices&rid=RID” | jq -r. result[]. Data’”.

It’s not working!
It seems that the returned data must be “0” or “1” and not “On” or “Off”. Do you have any idea how to transform “On” into “0” and “Off” into “1”??

lolouk44 · January 19, 2018, 10:38am

why don’t you adjust your template from:
{{ value_json.result[0].Data }}
to:
{% if value_json.result[0].Data == "On" %} 1 {% else %} 0 {% endif %} ?

DOESIT · January 21, 2018, 9:23pm

I tried this but it doesn’t work:

  command_on: '/usr/bin/curl k- "http://IP:PORT/json.htm?type=command&param=switchlight&idx=IDX&switchcmd=On"'
  command_off: '/usr/bin/curl -k "http://IP:PORT/json.htm?type=command&param=switchlight&idx=IDX&switchcmd=Off"'
   command_state: '/usr/bin/curl -s "http://IP:PORT/json.htm?type=devices&rid=IDX"'
   value_template: '{% if value_json.result[0].Data == "On" %} 1 {% else %} 0 {% endif %}'

lolouk44 · January 22, 2018, 1:57pm

Does you log state anything?
The syntax appears to be correct I can’t test the full command of course as I don’t have any value_json.result[0].Data to play with…
