Sending an email to multiple recipients is possible. Just add a comma “,” (no spaces) between the different email addresses in the <Email to> or in the <Email CC>.

Using BASIC Script

You can send emails through the Talk2M SMTP relay by using the SENDMAIL BASIC command.

  • Example:
SENDMAIL "[email protected]", "[email protected]", "Email Subject", "Email Body"

More information can be found in the Programming Reference Guide.
 

Send Text Messages (SMS)

You have the possibility to send text messages even if your Ewon is not equipped with a cellular extension card.
The process can be summarized as follows:
  • You configure the Ewon Flexy to send an email through the Talk2M SMTP relay like previously explained and you specify the recipient phone number inside the email address
  • The Talk2M relay transforms the email into a text message (SMS) and sends it to the phone number provided in the former email address.

This SMS sending is a Paid service of Talk2M.  Talk2M will charge 0.30 €/SMS on your account credit for the Free+ Account and 0.15€/SMS for the Pro Account.

 

Syntax

To send a text message (SMS) through the Talk2M relay, you must send an email to the following address:<mobilenumber>@sms.talk2m.com.


The mobile number format must begin with the international prefix phone number syntax starting. The international prefix is a or a series of 0 (zero) followed by the country code.


For example: use [email protected], to send a text message (SMS) to the phone number 0470123456 in Belgium (country code: 32).


Do not use the + sign instead of the (series of) 0 (zero) as this results in an error in the event logs as well as the scheduled actions.
