Know when a room turns dangerous.
Before someone gets hurt.
Wall-mounted WBGT and heat-index sensors watch every kitchen, warehouse and production floor — and text the right manager the moment conditions cross an OSHA threshold, with your company's own heat policy attached. Cellular units need no store network at all.
Proven in live restaurant deployments. Production units ship 2027.
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.
OSHA-aligned alert zones
Every chart shows the NWS/OSHA heat index bands — Safe, Caution, Extreme Caution, and Danger — so you can see at a glance where conditions have been and where they're headed.
Everything you need to stay compliant
True WBGT, not just heat index
A globe sensor measures radiant heat the way OSHA and ACGIH guidance expects — the five flag bands, on the unit's own display and in every alert. Units without a globe report heat index.
Live dashboard
Real-time conditions for every store, color-coded by alert band, with triage chips that answer 'is anything wrong?' in one glance across hundreds of locations.
Fleet map
See all your units on one map with street or satellite view. Color-coded markers show status at a glance.
7-day forecast
Weather-based heat index predictions. Our model learns each room's relationship to outdoor weather — including climate-controlled spaces.
Alerts that carry your policy
Texts and emails name the store, the reading, and what your company requires at that level — no binder lookup. One tap acknowledges, and the record shows who responded.
Escalation that climbs
Unacknowledged alerts escalate up your own chain — store, district, region — until someone owns it. Vacation coverage keeps the chain intact.
OSHA compliance reports
Auto-generated PDF reports showing monitoring activity, peak readings, and threshold crossings. Ready for regulatory audits.
History that holds up
Readings can never be edited or deleted — by you or by us. Up to 7 years of retention on Enterprise, with CSV export and date-range charts.
Roles and territories
District managers see their stores, regional VPs see their regions, and nobody responsible for a site can silence its alerts. Built for 2-unit shops and 500-store estates alike.
Business branding
Add your company name, logo, and brand color to the dashboard. Make it yours.
Cellular, no store IT required
Cellular units arrive provisioned: power on, assign a store, done. No Wi-Fi passwords, no firewall tickets. Firmware updates ship over the air — nobody visits a site for software.
