Number temperature2 “Temperature [%.1f°C]” {mqtt="<[broker:bruh/sensornode1:state:JSONPATH($.temperature)]"}
Number temperature3 “Real feel Temperature [%.1f°C]” {mqtt="<[broker:bruh/sensornode1:state:JSONPATH($.heatIndex)]"}

and below is sitemap
sitemap Home label=“MyHome”
{

Hi
thanks for help now few thing confusion about mqtt and sitemap becuase i am new i used to do work on Home assistant
Number LDR “LDR [%.1f%%]” {mqtt=“<[broker:bruh/sensornode1:state:JSONPATH($.ldr)]”}
how to print this currently its printer as Number

and how to do below mqtt in item and site map
platform: mqtt_json
name: “SN1 LED”
state_topic: “bruh/sensornode1”
command_topic: “bruh/sensornode1/set”
brightness: true
flash: true
rgb: true
optimistic: false
qos: 0
what i have to use for show rgb selection in site map as well in items

4

In order to Show the number item “LDR” on your sitemap just use:

Text item=LDR

Sorry, can’t help on the second question (new to that as well)

Hi
thanks for reply ,can you confirm how i read this mqtt for light
light:

  • platform: mqtt_json
    name: "SN1 LED"
    state_topic: "bruh/sensornode1"
    command_topic: "bruh/sensornode1/set"
    brightness: true
    flash: true
    rgb: true
    optimistic: false
    qos: 0

please if possible write item code for this rgb.
thanks

I have everything on the multisensor working through Openhab except for the LED. Anyone have an example for changing color, or have the native MQTT cmnd to change it manually from MQTT client?
Thanks!

Hi,
The led was pretty hard!

Example of payload: {“state”:“ON”,“color”:{“r”:255,“g”:255,“b”:255}}
remember to publish to your set topic (default: bruh/sensornode1/set)

You can also pass: transition(int) and flash(int)

So I have these items:

String Motion 	{mqtt="<[broker:bruh/sensornode1:state:JSONPATH($.motion):.*]"}
String SensornodeSet {mqtt=">[broker:bruh/sensornode1/set:command:*:default]"}

and rules to publish to that SensornodeSet topic

rule "alarmSetRedlight"
when
   Item Motion changed from standby to "motion detected"
then
  SensornodeSet.sendCommand("{\"state\":\"ON\",\"color\":{\"r\":255,\"g\":0,\"b\":0}}")
end

rule "alarmNolight"
when
   Item Motion changed from "motion detected" to standby
then
    SensornodeSet .sendCommand("{\"state\":\"OFF\",\"color\":{\"r\":0,\"g\":0,\"b\":0}}")
end
