[Solved]Pimatic REST API GPIO Switch?

---

Hello,
I try to use a second Raspberry Pi with pimatic. On the second RPI are relais installed which are switched over GPIO. I like to have my first RPI like a server, where I use the Web-Fronted. I tried now several times to switch on the other RPI the relais, but it did not work. Maybe somebody can tell me what i do wrong. E.g. I tried the following commands:

curl -X PATCH --header “Content-Type:application/json” --data ‘{“type”:“boolean”,“changeStateTo”: true}’ --user “user:password” http://xxx.xxx.xxx.xxx:8080/api/devices/relais1

Thank you Jodi

execute "sudo curl --silent --data 'state=true' http://ip_of_pimatric:8080/api/device/relais1/changeStateTo > /dev/null"

Thanks for the answer. I tried it with true and false state. Unfortunately it did not work on my pimatic. The state never change.

sorry, forget the user/pass part in my example:
execute "sudo curl --silent " --user "admin:admin" --data 'state=true' http://ip_of_pimatric:8080/api/device/relais1/changeStateTo > /dev/null"
Also if that doesn’t work try to to look at the error messages on the Pimatic you’re connecting to.
It’s the best to first try and play with the curl commands from commandline

Thanks again, I did the command from the command line. I tried /api/device and /api/devices at the http request, because it told me not to know the …/device/relais1, but it seems to know …/devices/relais1. Unfortunately the state did not change as well. When I look at the pimatic surface at Messages Info/Warn/Error nothing pop up. Don’t know what I do wrong… My command I typed is:

sudo curl --silent --data ‘state=true’ http://ip_of_pimatric:8080/api/devices/relais1/changeStateTo > /dev/null

Hi,

I tried now the following command:

sudo curl --data ‘state=true’ --user"user:password" http://XXX.XXX.XXX.XXX:8080/api/devices/relais1/changeStateTo

I get now the message

Cannot POST /api/devices/relais1/changeStateTo

The configuration of the switch looks like that:

{“device”:
{“id”:“relais1”,
“name”:“Relais1”,
“template”:“switch”,
“attributes”:[
{“description”:“The current state of the switch”,
“type”:“boolean”,
“labels”:[“on”,“off”],
“label”:“State”,
“discrete”:true,
“name”:“state”,
“value”:false,
“history”:[
{“t”:1485723808913,
“v”:false},
{“t”:1485724026009,
“v”:false},
{“t”:1485779324396,
“v”:true},
{“t”:1485779326678,
“v”:false}],
“lastUpdate”:1485779326678}],
“actions”:[
{“description”:“Turns the switch on”,
“name”:“turnOn”},
{“description”:“Turns the switch off”,
“name”:“turnOff”},
{“description”:“Changes the switch to on or off”,
“params”:{
“state”:{“type”:“boolean”}
},
“name”:“changeStateTo”},
{“description”:“Toggle the state of the switch”,
“name”:“toggle”},
{“description”:“Returns the current state of the switch”,
“returns”:{
“state”:{“type”:“boolean”}
},
“name”:“getState”}],
“config”:{
“gpio”:19,
“id”:“relais1”,
“name”:“Relais1”,
“class”:“GpioSwitch”,
“inverted”:true},
“configDefaults”:{
“inverted”:false}},
“success”:true}

Hope somebody can help.

Thanks in advanced,
Jodi

Are you using api/device/relais1 of api/deviceS/relai1 ?
for the ChangeStateTo part to work you must need the part /device/ without the S on the end (like my first example)
Also try it in a browser : http://xxx.xxx.xxx.xxx:8080/api/device/relais1/changeStateTo?state=true

Hi koffienl,

I tried it in the browser. This worked. I got the result:
{“result”:true,“success”:true}
Unfortunately when I use the command line with the command:

sudo curl --data ‘state=true’ --user “user:password” http://xxx.xxx.xxx.xxx:8080/api/device/relais1/changeStateTo

I get the reply:

Cannot POST /api/device/relais1/changeStateTo

I have no clue what I do wrong…

put -x GET right after curl

!It works! Thank you very much!
