SMTP
Server settings for sending email alerts.
Email services
Alerts
Email alerts from device item rule engine (digital/analog/global).
Where are emails used?
Alerts engine evaluates device item rules (digital/analog/global) and sends notifications to target users.
Per‑user preferences define recipients, enabled channels, and minimum send interval.
Cooldown prevents flooding: per rule and per user/device throttling is enforced.
SMTP must be configured and enabled; toggle and credentials are in the SMTP tab.
Diagnostics: alert processing logs go to logs/alerts.log and Console.
