Hi I discovered openHab
I have a lot personal IOT devices who work with HTTP get request

for example a switch to light the light are write

http://xxx.xxx.xxx/set.htm?D12=
the answer are the state of the relay.

I try different configuration but no are all functional.
when I used for exemple if the D12=1 i can change the state
but if I used of OFF to ON the request is launch but no change on my device.
what is the best configuration in this case, how to variabilise the get reqest ?
I try this configuration for the think :

UID: http:url:1f0999da96
label: Lampadaire Bureau ESP32
thingTypeUID: http:url
configuration:
  authMode: BASIC
  ignoreSSLErrors: false
  baseURL: http://192.168.10.180/
  delay: 0
  stateMethod: GET
  refresh: 100000
  commandMethod: GET
  contentType: text/html
  timeout: 30000
  bufferSize: 2048
location: Bureau
channels:
  - id: switch
    channelTypeUID: http:switch
    label: switch
    description: ""
    configuration:
      onValue: "0"
      mode: READWRITE
      offValue: "1"
      stateExtension: get.htm?D12
      commandExtension: set.htm?D12=

I waited the Best Solution and understand how to configure in the best way the add-on to used this component

You’ll have to add the command to the URL:

UID: http:url:1f0999da96
label: Lampadaire Bureau ESP32
thingTypeUID: http:url
configuration:
  authMode: BASIC
  ignoreSSLErrors: false
  baseURL: http://192.168.10.180/
  delay: 0
  stateMethod: GET
  refresh: 100000
  commandMethod: GET
  contentType: text/html
  timeout: 30000
  bufferSize: 2048
location: Bureau
channels:
  - id: switch
    channelTypeUID: http:switch
    label: switch
    description: ""
    configuration:
      onValue: "0"
      mode: READWRITE
      offValue: "1"
      stateExtension: get.htm?D12
      commandExtension: set.htm?D12=%2$
//                                  ^^^

Because, as mentioned in the documentation, you need to add the format parameter too. Try %2$s instead of just %2$.

If that doesn’t work, please share your new configuration.
