[SOLVED] How can I work with the item value {"value":false}

Master79 · December 29, 2018, 2:47am

Hi to all.
After using this:

#!/bin/sh
NanoStatus=`curl -X GET -H "Content-Type: application/json" -d '{"on" : {"value":true}}' "http://192.x.x.x:16021/api/v1/xxx/state/on"`
echo "NanoStatus is: "$NanoStatus
#
curl --header "Content-Type: text/plain" -H POST  "http://192.x.x.x:8080/rest/items/NanoStatus"  --data "$NanoStatus"
#
NanoSelect=`curl -X GET -H "Content-Type: application/json" -d '{"on" : {"value":true}}' "http://192.x.x.x:16021/api/v1/xxx/effects/select"`
echo "NanoSelect is: "$NanoSelect
#
curl --header "Content-Type: text/plain" -H POST  "http://192.x.x.x:8080/rest/items/NanoSelect"  --data "$NanoSelect"
#
NanoBrightness=`curl -X GET -H "Content-Type: application/json" -d '{"on" : {"value":true}}' "http://192.x.x.x:16021/api/v1/xxx/state/brightness"`
echo "NanoBrightness is: "$NanoBrightness
#
curl --header "Content-Type: text/plain" -H POST  "http://192.x.x.x:8080/rest/items/NanoBrightness"  --data "$NanoBrightness"
#

I get this:

2018-12-28 02:58:00.056 [ome.event.ItemCommandEvent] - Item 'NanoStatus' received command {"value":false}

2018-12-28 02:58:00.081 [ome.event.ItemCommandEvent] - Item 'NanoSelect' received command "Earth Day"

2018-12-28 02:58:00.107 [ome.event.ItemCommandEvent] - Item 'NanoBrightness' received command {"value":46,"max":100,"min":0}

How can i work with the value {“value”:false} or {“value”:46,“max”:100,“min”:0}.
Or is something wrong in my curl request?
I am searching for examples, but cannot find something like this.
Thanks for help and greetings,
Markus

It would’ve helped if you had included the output of the script.

Item 'NanoStatus' received command {"value":false}

It’s not apparent where this output comes from, since none of the script lines you showed includes it.

Hi namraccr.
I have only this description in the api documentation.

curl --location --request GET "http://192.168.x.x:16021/api/v1/Add-a-user-to-generate-auth-token/state/on"

and example request:

{
  "value": true
}

And in my script, i send a request for this state and give the answer to the item Nanostatus. Line 2 and 5. Sorry, but i don’t know what you mean. Can you explain me, what you need?
Greetings, Markus

Can you post the items and/or the rules that you use to get the value into OH
You will need a JSONPATH transformation to extract the value from the generated JSON strings

Master79 · December 29, 2018, 9:28am

Yes, no problem.

nano.item:

String NanoStatus "NanoStatus"
String NanoSelect "NanoSelect"
String NanoBrightness "NanoBrightness"

rule "Skript nanoget.sh alle 30 Sekunden laden"

when
 Time cron "0/30 0/0 * * * ?"
then
  executeCommandLine("/etc/openhab2/scripts/nanoget.sh", 10000)
  //logInfo("Skript nanoget.sh", results)
end

Greetings,
Markus

Install the JSONPATH transformation service in the PaperUI

rule "Skript nanoget.sh alle 30 Sekunden laden"
when
 Time cron "0/30 0/0 * * * ?"
then
    val jsonString = executeCommandLine("/etc/openhab2/scripts/nanoget.sh", 10000)
    //logInfo("Skript nanoget.sh", results)
    NanoStatus.postUpdate(transform("JSONPATH", "$.value", jsonString))
end

See: https://www.openhab.org/docs/configuration/transformations.html#usage

Hi Vincent.
I have changed it and get now:

 The name 'jsonString' cannot be resolved to an item or type;

Greetings,
Markus

vzorglub · December 29, 2018, 4:43pm

Show me your code and try:
val String jsonString = executeCommandLine("/etc/openhab2/scripts/nanoget.sh", 10000)

That’s in the logs now:

And this is the rule:

rule "Skript nanoget.sh alle 1 Minuten laden"

when
 Time cron "0 0/1 * * * ?"
then
 val String jsonString = executeCommandLine("/etc/openhab2/scripts/nanoget.sh", 10000)
  //logInfo("Skript nanoget.sh", results)
  NanoStatus.postUpdate(transform("JSONPATH", "$.value", jsonString))
end

What exactly are you trying to achieve here?
Can you post your items?

Master79 · December 29, 2018, 7:26pm

I want to transform the item value Nanostate to On or Off and the item value Nanobrightness to xx%.
The items are:

String NanoStatus "NanoStatus"
String NanoSelect "NanoSelect"
String NanoBrightness "NanoBrightness"

Nanoleaf is a light and i can switch it by the script from Dennis (mrJakez).
But i miss the actual state of the item. When i use the light for notification warnings, i have to know, if the light is On or OFF and which scene is on, to the set the previous state. Therefore i wrote the script and now i get the item values. But cannot work with it. I think the script is not right too, because i have copyed it and make it runnable with my knowledge.

Master79 · December 29, 2018, 11:04pm

Got it.

rule "Skript nanoget.sh alle 1 Minuten laden"

when
 Time cron "0 0/1 * * * ?"
then
  executeCommandLine("/etc/openhab2/scripts/nanoget.sh", 10000)
  
  var String jsonString = (NanoStatus.state as StringType).toString
  var String jsonString1 = (NanoBrightness.state as StringType).toString 
  
  NanoStatusK.postUpdate(transform("JSONPATH", "$.value", jsonString))
  NanoBrightnessK.postUpdate(transform("JSONPATH", "$.value", jsonString1))
end

Thanks to all and Greetings,
Markus
