Centralized System Alerts & Notifications

Stay informed of cellular drops, carrier tower handoffs, SIM swaps, and hardware reboots.

How QManager Alerts Work#

Traditional routers send email alerts when internet goes down. But if internet is down, email cannot be sent!

QManager solves this with a Dual-Channel Notification Strategy:

1. Email Alerts (Post-Recovery): Sent once WAN connectivity is restored, providing full incident report, downtime duration, and recovery tier details.
2. SMS Control Channel Alerts (During Outage): Sent during the active outage over the cellular baseband control channel via sms_tool, reaching your phone even while the IP data link is completely offline!

Cellular Control Channel Alerts#

• Reaches you even if data routing is frozen.
• Features de-duplication to prevent SMS spam during transient tower flickers.
• Configurable threshold (e.g. only alert if outage exceeds 5 minutes).

Email (SMTP) Alert Configuration#

Configure lightweight msmtp in Messages > Alert Settings:

• Host: smtp.gmail.com (or any custom SMTP server)
• Port: 587 (STARTTLS) or 465 (TLS)
• App Password authentication.
