The email node

Send an email to one or more recipients

Note: This node is a sink node and does not output any flow-data, therefore any node connected to this node will not get any data.

Example

|email()
.to('name@email.com')
.subject('Alert #ex3 EnergyData {{"building"}}')
.body('
    No data since {{"datetime"}} on topic ''home/garage/energy'', 
    last value was {{"val"}}. 
    ')

Sends an email with the subject 'Alert #ex3 EnergyData'.

The body will be rendered into an html template (see parameters). Body is a text_template parameter with two template-values: datetime and val, these two fields must be present in the data_point last received in the email node. If a field used in a text_template is not found in the current data_point, the string 'undefined' will be used.

|eval(lambda: str_concat('Module', "mod_number"))
.as('email_subject')
|email()
.to('name@email.com','another@email.com')
.subject_field('email_subject')
.body('
    No data since {{"datetime"}} on topic ''home/garage/energy'', 
    last value was {{"val"}}. 
    ')

Sends an email with the subject build with a lambda expression to 2 recipients.
