Hi there,
I have recently started to connect my existing home automation hardware to OH3.
I am using the latest version of OH from openhab.org on a Linux PC. HTTP binding and JSONPATH installed.
My hardware provides a HTTP server and can be controlled using a REST API and JSON. I got it managed that roller shutters and simple switches are already working, however I got stuck with full-color lights: My HTTP server returns two objects for a full-color LED stripe:
{
"RGB1_1": {
"value": "32767",
"level": 0,
"type": "FB Switch",
"age": 1
},
"RGB1_1_COL": {
"value": "36,100,50",
"level": 0,
"type": "Color",
"age": 2
}
}
I used the following configuration for the HTTP binding to create a “Testroom” thing:
UID: http:url:2714827e25
label: Testroom
thingTypeUID: http:url
configuration:
authMode: BASIC
ignoreSSLErrors: false
baseURL: http://192.168.1.43/signal/
refresh: 1
commandMethod: PUT
contentType: application/json
timeout: 3000
bufferSize: 8192
channels:
- id: RGB1_1
channelTypeUID: http:switch
label: "LED Stripe On/Off"
description: null
configuration:
onValue: "32767"
offValue: "0"
stateTransformation: JSONPATH:$.RGB1_1.value
commandExtension: RGB1_1
- id: RGB1_1_COL
channelTypeUID: http:color
label: "LED Stripe Color"
description: null
configuration:
mode: READWRITE
colorMode: HSB
stateTransformation: JSONPATH:$.RGB1_1_COL.value
commandExtension: RGB1_1_COL
I’ve used the graphical UI to connect the two channels to items: a switch and a color item. The switch item works fine, however the color item already shows up in the overview with UNDEF data. Setting a color using HABPanel works (i.e. the right PUT request with valid data is fired), but the color picker will be reset to “black” as soon as a new color was entered.
The log doesn’t output any errors.
Any thoughts on what I’ve missed / did wrong?
