WiFi sensor can send alarm emails directly via SMTP server. Device can
send warning email when alarm on channel occurs or alarm is cleared. Email
on system alarm can inform about measurement error or other hardware
related issues. Device can send keep alive emails and repeat warning emails
when alarm on channels persists.
In case of ATAL Onlinesensor or ATAL Database is used, it is not mandatory
set sending emails from device itself. ATAL Onlinesensor and ATAL
Database have independent way how to send warning emails.

need to be properly set. Information how to set SMTP parameters can
provide network administrator. SMTP server address and port need to be set
according to used server. When SMTP authentication is used it needs to be

email sender. When encrypted communication with server is used it can be
enabled TLS or STARTTLS feature. Common combinations of SMTP port,
