[Solved] Bash command to update a variable

temp

Hello,
is this syntax correct to update a variable?

curl --insecure -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": '"${pimatic_var_value}"'}' --user "${PIMATIC_USER}:${pimatic_pwd}" http://$PIMATIC_HOST/api/variables/$pimatic_var >/dev/null 2>&1

Thanks.

But is is not working

curl --silent -X PATCH --header "Content-Type:application/json" --user "test:test" --data '{"type": "value", "valueOrExpression": "20"}' http://smarthome:5000/api/variables/variable_string_today > /dev/null

what exactly does not work? do you have the debug or error message for us?
from where do you call the curl command? bash, pimatic rule, pimatic device etc…

temp

No, i don’t have any debug info. I try to change it from an other Linux PC. The value hasn’t changed

Gleno0h

@temp well, if you dont remove “–silent” and “> /dev/null” you wont get any output/debug data…

This works just fine:

curl --silent -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "YOURVALUEHERE"}' --user "USERNAME:PASSWORD" http://IPADDRESS:PORT/api/variables/VARIABLE > /dev/null

So in your case asuming you have a variable “$variable_string_today”:

curl --silent -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "20"}' --user "test:test" http://smarthome:5000/api/variables/variable_string_today > /dev/null

Wrong port number

Sorry

The goal is to switch in a switch if a defined time and date is reached. I like to send the time and date info via curl to the variable and check that variable against current time. Which format do I need to send?

Gleno0h

@temp this is already build in? WHEN its 22:00 THEN …?

And what do you mean by wrong port number? You have it fixed because you used the wrong port?

Also, what time do you want to send?
System time or just “17:00” ?

"valueOrExpression": "17:00"

temp

Yes, i fixed it with the correct port number.

The variable has then the value 2.10.2017-17:00:00 and the rule shoud check if it is 2.10.2017-17:00:00 and switch on the wall plug.

Gleno0h

@temp idk what you exactly want but ill give you a hint.

Lets define the time first:

systemtime=$(date '+%X')

You can now manipulate how you want to output the time. Experiment with it.

Then, to use it with curl:

curl --silent -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$systemtime'"}' --user "test:test" http://IPADDRESS/api/variables/your_variable > /dev/null

So, paste this in your bash:

systemtime=$(date '+%X')

curl --silent -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$systemtime'"}' --user "test:test" http://IPADDRESS/api/variables/your_variable > /dev/null

This will write 11:20:10 to your variable.

Want only the current day?
Use date '+%A'
want day and time?
Use ```date ‘+%A %X’``

Or simply use
systemtime="2.10.2017-17:00:00" if you want to use a fixed time

@temp i dont know. Post your bash script?

I also see you have date in ’ ’ tags, thats wrong. I also see $ t. Why is there a space? Should be $t.

Post your bash pls

temp

This post is deleted!

Hello,

  t=`date -d@$timestamp +%d-%m-%Y\ %H:%M`
 curl -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$t'"}' --user "a:a" http://smarthome:5001/api/variables/variable_string_today

mwittig

@temp Looks like the command spans multiple lines including line breaks. Note, line breaks are not supported and need to be escaped with an \ at the end of the line, e.g.

curl -X PATCH --header "Content- \     
 Type:application/json" --data '{"type": "value",\
  "valueOrExpression": "'$t'"}' --user "a:a"  \
      http://smarthome:5001/api/variables/variable_string_today

Gleno0h

@temp what @mwittig said and following line doesnt make sense to me…

t=`date -d@$timestamp +%d-%m-%Y\ %H:%M`

t=date -d ‘+%d-%m-%Y\ %H:%M’ makes more sense to me, except for -d. Thats invalid… Why do you have @$timestamp?

Also why the \ ?

Please let me know what you want and ill post a bash code you can copy and use.

everything is fine if I use

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y/%H:%M`

instead of

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y\ %H:%M`

@temp im sorry i still dont know what you want. Did you solve it or not?

I get this error

If I am using this line for defining the Start time

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y\ %H:%M`

When I use this line

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y/%H:%M`

Everything is good

But i like to see in the pimatic GUI the format

16-05-2017 17:30

And not

16-05-2017/17:30

Gleno0h

@temp well, you define it yourself in your date command…

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y/%H:%M`

But you want:

wake_start_time=`date -d@$wake_start_timestamp +%d-%m-%Y %H:%M`

As you can see, i only removed the /…

NSA@raspberrypi:~# date '+%d-%m-%Y/%H:%M'
16-05-2017/23:46
NSA@raspberrypi:~# date '+%d-%m-%Y %H:%M'
