control 2nd pimatic via api

---

hello,

i ve 2 pimatic system

the first is my mainsystem (192.168.1.2), the second in the barn (192.168.1.3).
in the barn i have a dimmer. how can i control this device with the main system?

i use this device in the barn:

    {
      "id": "rfswitch",
      "name": "Dimmer",
      "class": "HomeduinoRFDimmer",
      "protocols": [
        {
          "name": "dimmer1",
          "options": {
            "id": 17494366,
            "unit": 0
          }
        }
      ]
    },
    {
      "id": "stall-dimmer",
      "name": "Hühnerstall Dimmer",
      "class": "VariablesDevice",
      "variables": [
        {
          "name": "dimlevel",
          "expression": "$rfswitch.dimlevel",
          "type": "number"
        }
      ]
    },
    {
      "id": "dimmer-buttons",
      "name": "Dimmer Button",
      "class": "ButtonsDevice",
      "buttons": [
        {
          "id": "dim-plus",
          "text": "Dim +"
        },
        {
          "id": "dim-minus",
          "text": "Dim -"
        }
      ]
    }

with this rule

    {
      "id": "lichtplus",
      "name": "LichtPlus_Morgens",
      "rule": "if its after 6:00 and before 7:00 and every 20 seconds and $rfswitch.dimlevel < 100 then dim Dimmer to $rfswitch.dimlevel +1",
      "active": true,
      "logging": true
    }

@noxx Did you looked at the API documentation ?

no, where can i find this?

edit:

this?
https://pimatic.org/guide/api/

https://pimatic.org/api/actions/#scrollNav-5 -> go to callDeviceAction
You will see the explanation :

GET /api/device/:deviceId/:actionName

Thus, to control a device over the API you should call http://pimatic/api/device/deviceid/turnOn to turn on a device.
To find out what Actions you device has, get all the device info via the API : http://pimatic/api/devices/deviceid
note : the first API all uses /device the seconde /devices (extra S).

thx… i try this: http://192.168.1.225/api/devices/rfswitch/
and get:

{
“device”: {
“id”: “rfswitch”,
“name”: “Dimmer”,
“template”: “dimmer”,
“attributes”: [
{
“description”: “The current dim level”,
“type”: “number”,
“unit”: “%”,
“label”: “Dimlevel”,
“discrete”: false,
“name”: “dimlevel”,
“value”: 0,
“history”: [
{
“t”: 1455654200679,
“v”: 29
…

but http://192.168.1.225/api/devices/rfswitch?value=10
dont work
i want change the dimlevel of a dimmer

found it

http://192.168.1.225/api/device/rfswitch/changeDimlevelTo?dimlevel=10

Great!

but, how can i use this in a rule
"rule": “if its after 6:00 and before 7:00 and every 20 seconds and $rfswitch.dimlevel < 100 then dim Dimmer to $rfswitch.dimlevel +1”

It is not possible to native call the API in pimatic itself. You should call the API via a curl command.
here I explain how to call curl in a rule. For pimatic you would need to add username and password.
A rule would look something like this:
execute "curl --silent --user \"api:admin\" --data '\{\"type\": \"value\", \"valueOrExpression\": $waterin.temperature\}' http://192.168.2.118:82/api/variables/ZwembadWaterIn > /dev/null"

thx for the links, but i find the desciption very complicated.

perhaps you can help me with my example.

1. master-system: how can add the dimmer of my barn as device in my master-system?
   (i know this code isnt right)

   {
   “id”: “barn-led-dimmer”,
   “name”: “rfswitch”,
   “class”: “ApiDimmer”,
   “adress”:“192.168.1.225:80”
   }

or

“rule”: "if its after 6:00 and before 7:00 and every 20 seconds and http://192.168.1.225/api/device/rfswitch/dimlevel < 100 then dim Dimmer to http://192.168.1.225/api/device/rfswitch/changeDimlevelTo?dimlevel=dimlevel+1

(sorry for no code blocks…sometimes goes automatically. then not again.
do not have the desire to learn and the heart

Your dimming logic should be complete on your second pi and implement an dummy switch.
From your second pimatic (master) your switch the dummyswitch over the api and it should work,

Slave Rule example
"if DUMMYSWITCH is on and every 20 seconds and $rfswitch.dimlevel < 100 then dim Dimmer to $rfswitch.dimlevel +1"

Master Rule
"if its after 6:00 and before 7:00 then execute “curl --silent …”
