LG Webos show items value on TV

Hello, I successfully use LG TV, where I display, for example, Toast messages to children. However, I cannot use the Toast message to display the value of items when it is changed, please advise? Thank you

Here is a sample rule, when the hot water circulation is started, messages appear on the TV that in 5 minutes they should go for a bath. I would also like to transfer, for example, the time or temperature of the boiler

configuration: {}

  • id: “3”
    command: ON
    itemName: GenericMQTTThingESP826604data_HotWater
    type: core.ItemCommandTrigger
  • inputs: {}
    id: “1”
    itemName: TV_kids_Power
    state: ON
    operator: =
    type: core.ItemStateCondition
  • inputs: {}
    id: “2”
    command: Cirkulace vody puštěna, za 5 minut do vany kdo je na řadě!
    itemName: LGTVkids_Toast
    type: core.ItemCommandAction

Items with boiler is this

I must be missing some syntax or something, but I can’t figure it out, thanks

In order to dynamically built a message that will include the item state you need to add a script action to the rule.

If you are new to scripting I would recommend using blockly, as this is most likely the easiest way to start
