Automated Reefer Pre-Cool Reminders
Every hour, WebRun reads your upcoming pickups from Google Calendar, checks each assigned trailer's current box temperature in Wireless Links Fleet.Net, and posts a Slack reminder to pre-cool any reefer not yet at loading temperature while queuing the remote pre-cool command for a dispatcher to approve.
How do I make sure reefers are pre-cooled in time for each scheduled load?
WebRun reads upcoming pickups from Google Calendar every hour and checks each assigned trailer's box temperature in Wireless Links Fleet.Net. When a reefer will not reach loading temperature in time, it posts a Slack reminder and queues the remote pre-cool command for a dispatcher to approve, so trailers are ready and reefer hours are saved.
- Trailers reach loading temperature before the driver arrives to load
- Reefer hours and fuel are saved by starting pre-cool just in time
- The remote start command always waits for a dispatcher to approve

Every action is checked against this policy before it runs.
Questions, answered
Will it start the reefer remotely on its own?
No. WebRun posts the reminder and queues the remote pre-cool command in Fleet.Net, but leaves it for a dispatcher to approve. Starting a unit is a physical action, so it always waits for human sign off.
How far ahead does it plan the pre-cool?
It uses your lead window and each trailer's pull down rate to decide when pre-cool must start so the box hits target before the pickup time. You can widen the lead window in your run settings.
What if the trailer is already at temperature?
It reads the live box temperature each hour, so any trailer already at its load target is marked ready and no pre-cool reminder or command is created for it.
