⁠Description

This module enables a customized composition of messages, in example alert messages that can be later passed to the next module like Slack Alert which would further pass it to the selected Slack endpoint channel. To include some data in the message use double curly brackets and provide a desired label like {{ label_name }}. To use one of the supported utils functions to add extra information to your message, use double curly brackets and prefix utils. before the name of the function you want to apply {{ utils.function_name }} (see Supported Utils Functions section below).

For instance, if we expect to receive data in the following format:

{
    "temperature": 12,
    "volume": 375,
    "location": "Berlin"
}

and if we have our Message Label set to alertMessage and our Message Content variable is set to the following:

Device {{utils.getNodeName}} (in {{location}}) measured temperature {{temperature}} on {{utils.getDateAndTime}}

then the output of the module will be:

{
    "alertMessage": "Device Kunbus (in Berlin) measured temperature 12 on 2022-09-25 15:35:17.31234"
}
