OH 3 Channel disappears

Setup, Configuration and Use Beginners

Hi,

unfortunately one channel from my generic MQTT Thing disappears after refreshing the page or navigating to somewhere else. This is my YAML code:

UID: mqtt:topic:broker:Trockner
label: Trockner
thingTypeUID: mqtt:topic
configuration:
  payloadNotAvailable: offline
  availabilityTopic: tele/sonoff/trockner/LWT
  payloadAvailable: online
bridgeUID: mqtt:broker:broker
location: Waschküche
channels:
  - id: Trockner Verbrauch Aktuell
    channelTypeUID: mqtt:number
    label: Energy
   description: ""
   configuration:
      stateTopic: tele/sonoff/trockner/SENSOR
      transformationPattern: JSONPATH($.ENERGY.Power)
      unit: W

Any idea?

Disappears from where? Is that the YAML before the Channel disappears? Are you clicking Save after making any changes? Have you edited any of the properties which have a UID in the name?

Also, your transformation pattern syntax is wrong: check the other thread again!

Yes, JSONPATH is wrong, but that´s not the source of the problem.

I added a blank channel for testing, but it also disappears completely from the things channel list.

  • The YAML code is the code before it disappears.
  • Yes, I saved.
  • Have not edited any other properties

This must not contain spaces.

yeah, that´s what I was just guessing after I tested this now and that channel disappeared only:

label: Trockner
thingTypeUID: mqtt:topic
configuration:
  payloadNotAvailable: offline
  availabilityTopic: tele/sonoff/trockner/LWT
  payloadAvailable: online
bridgeUID: mqtt:broker:broker
location: Waschküche
channels:
  - id: test
    channelTypeUID: mqtt:number
    label: test
    description: ""
    configuration: {}
  - id: Trockner Verbrauch Aktuell
    channelTypeUID: mqtt:number
    label: Energy
    description: ""
    configuration: {}

Ok, let´s see if this is just the solution…
