OH3 Http Binding Switch ESP01

Setup, Configuration and Use Beginners
1

Hello Forum,
I programmed a ESP01 with Arduino IDE (no Tamota, connected to my WLAN) to blink in a Lighthouse Sequence .
Now I want to turn the Sequence on and off whit a OH3 Http Binding Switch.
When I manually type 192.168.0.23/whvon in a Browser the Seqence starts and /whvoff it stops.

OH is running on a Raspberry 3.

Here is the Code:

UID: http:url:acd697c3a2
label: Lighthouse
thingTypeUID: http:url
configuration:
  authMode: BASIC
  ignoreSSLErrors: false
  refresh: 30
  baseURL: 192.168.0.23/
  commandMethod: GET
  contentType: text/html
channels:
  - id: Whv
    channelTypeUID: http:switch
    label: Whv
    description: ""
    configuration:
      onValue: whvon
      offValue: whvoff
      commandExtension: "%2$s"

I read this Post (Http binding OH3, how to create a switch channel in UI?), but unfortunately it won’t work.

Can you please halp me? What is wrong?

Kind regards and stay healthy, Helmut

Of you Set the Loglevel to TRACE you can see what is sent and what the answer is. Please post that.

Hi Jan,
I tried to set the Loglevel to TRACE with this command in a Terminal:
sudo log:set TRACE org.openhab.binding.http
It said that the command was not found. Writing mistake?
From the “normal log” in Openhab I found this:

2021-04-05 08:21:21.389 [INFO ] [openhab.event.ItemCommandEvent ] - Item ‘LskTest_Whv’ received command OFF

Hmmm…it seems that OH sends the On and Off, but not in /whvon and /whv off? Why does the System start a Mqtt Broker when I’m on http?
I try to switch to TRACE, but wanted to report this to you first.

Kind regards, Helmut

I’m pretty sure you need:

baseURL: http://192.168.0.23/

Hi,
partial solution with http://192.168.0.23 :slight_smile:
I can turn it on and off but after 14 sek off the Sequence starts running again whitout that I do anything. Seems that by changing from OFF to UNDEF it starts again.

2021-04-05 09:29:00.123 [INFO ] [penhab.event.ItemStatePredictedEvent] - Item ‘LskTest_Whv’ predicted to become OFF

2021-04-05 09:29:00.130 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item ‘LskTest_Whv’ changed from ON to OFF

2021-04-05 09:29:14.572 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item ‘LskTest_Whv’ changed from OFF to UNDEF

How can I avoid switching from OFF to UNDEF?

Regards, Helmut

I’ve got it :slight_smile:
It switched to UNDEF after the Refresh time. Setting it to “Write only” made it work.
