How it works
Mount the sensor
Plug in a HeatAlert device, connect it to Wi-Fi via the setup portal on your phone, and pair it with your dashboard.
Monitor in real time
Temperature, humidity, and heat index stream to your dashboard every 60 seconds. Color-coded alerts match NWS/OSHA standards.
Get notified before it's dangerous
Email and SMS alerts fire when heat index crosses into Caution, Extreme Caution, or Danger — before your workers are at risk.
See every facility on one map
Color-coded markers show each unit's status at a glance. Street or satellite view. Click any marker for live readings and a direct link to the unit detail page.
Live readings + predictive forecast
Each unit's page shows the current heat index with a color-coded ring, plus a 7-day forecast that learns your building's relationship to outdoor weather. Know when Danger is coming — before your workers feel it.
