Every unit measures temperature and humidity, computes the heat level on board, and shows it on its own round display at the site.
There is one monitor, with two options you choose per unit. Both are physical, so both are part of what that unit costs once — not something added to your subscription.
| Option | What it changes | Without it |
|---|---|---|
| WBGT globe probe | Adds radiant heat, upgrading the reading from heat index to full WBGT — the measure OSHA guidance is written in. | The unit still monitors, still alerts and still escalates, on heat index. Nothing about the safety pipeline changes. |
| Cellular radio | The unit reports over the mobile network and needs no store network at all. | The unit joins the store's Wi-Fi during a short setup step. |
A cellular unit involves two separate charges, and they're easy to confuse: the radio is part of the hardware, once, and the mobile data it uses each month is the cellular add-on on your subscription. A Wi-Fi unit has neither.
The display is not a convenience. It means the people in the room are warned whether or not the network, the dashboard or anyone's phone is working. Everything else in this product is remote oversight layered on top of that.
Units need continuous power. They are not battery devices — a heat monitor that switches itself off to save power is not a heat monitor.
