5.6.5 E-mail service
HT22IoT monitors have been equipped with a function to send email messages
using SMTP.
To send a message the user must provide authentication data to SMTP proxy
server. The server should be located in the same network as the device.
Caution:
SMTP proxy server must support AUTH PLAIN
authentication for unencrypted connection.
The service allows the user to send information about alarm events and information in the
form of regular short e-mail messages that contain the following information:
•
The time at which the event occurred,
•
The quantity that caused the event,
•
The measured values which occurred at the moment of alarm status change,
•
The name of the device from which the information was sent.
HT22IoT monitor has a memory buffer allowing for storage of maximum of 20 e-mail
messages. If an e-mail can not be sent on a regular basis, for example, due to lack of
connection they are queued up one after the other until their number does not exceed 20.
When the limit is exceeded, the subsequent messages will be lost. In the case of
transmission errors, wrong configuration or other factors beyond the control of the device
(e.g. Anti-spam protection of SMPT server), the messages may not reach the recipient.
