OH3 Tasmota MQTT current energy

I have a Powerplug with Tasmota. In MQTT.fx it sends Power ON OFF and the SENSOR like this

{"Time":"2021-01-22T20:26:48","ENERGY":{"TotalStartTime":"2020-06-22T12:31:48","Total":2.514,"Yesterday":0.000,"Today":0.170,"Period":4,"Power":54,"ApparentPower":211,"ReactivePower":204,"Factor":0.26,"Voltage":227,"Current":0.929}}

Integrated in OH3 only the ON / OFF switch is working via Generic MQTT Device, but when I want to measure Sensor stats like the Current Power Use it shows only NULL

I opened a Channel at this Thing as Number with JSONPATH:$.ENERGY.Current it´s not working.

What I´m doing wrong?

As per example provided below JSONPath Expression try to use:
$.ENERGY.Current
instead of JSONPATH.$.ENERGY.Current

To be honest I am guessing. All my MQTT items things are created by code. And I don’t have multilevel JSON’s :slight_smile:

Thank you, but I don´t know where to put at OH3 :frowning:

Thank you 4 your Link, but I think JSONPATH. have to be in front

Did you try it? Because you selected JSONPATH above the expression field, it looks like you don’t need it in the expression field itself. See the example underneath the expression field.

Yes, sure I tried it first - thank you :grinning:

Try to do it manually:


go to the newly greated Thing and add below code

UID: mqtt:topic:Waschmachine:Waschmachine1
label: Waschmachine
thingTypeUID: mqtt:topic
configuration: {}
bridgeUID: mqtt:broker:Waschmachine
location: 
channels:
  - id: Cyrrent
    channelTypeUID: mqtt:number
    label: Current
    description: null
    configuration:
      stateTopic: HERE_YOU_NEED_TO_PUT_MQTT_TOPIC
      transformationPattern: JSONPATH:$.ENERGY.Current


Be carefull with stateTopic.

In next step create the link for this new channel.
