Automated Reefer Unit Alarm Escalation
Every few minutes, WebRun opens Wireless Links Fleet.Net, scans for reefer unit alarm and fault codes, posts each active alarm to a Microsoft Teams maintenance channel with its severity, and drafts a Twilio SMS to the on-call technician so a failing reefer unit gets a fast response, with the text held for approval.
How do I escalate a reefer unit alarm to my on-call technician quickly?
WebRun scans Wireless Links Fleet.Net every few minutes for reefer unit alarm and fault codes. It posts each active alarm to a Microsoft Teams maintenance channel ranked by severity, and for critical faults it drafts a Twilio SMS to the on-call technician, held for approval, so a failing reefer unit gets a fast, controlled response.
- Critical reefer faults reach the on-call tech within minutes of the alarm
- The maintenance team sees every alarm ranked by severity in one channel
- Escalation texts stay under supervisor approval, never auto sent
Built for reefer carriers · fleet maintenance teams · cold chain fleets · reefer service techs

Questions, answered
Will it text the on-call technician without approval?
No. WebRun drafts and queues the on-call SMS in Twilio and leaves it unsent for a supervisor to approve. The internal Teams post is automatic, but the external text always waits for a human.
Which alarms escalate to a text versus just a Teams post?
You set the severity threshold. Lower severity alarms are posted to the maintenance Teams channel only, while high severity alarms, especially with a load aboard, also draft an on-call technician SMS.
What if the alarm clears before anyone responds?
It rechecks Fleet.Net every few minutes, so a resolved alarm is marked cleared in the Teams thread and any pending draft for it is withdrawn automatically.
