Wi-Fi temperature monitoring
Know the moment it crosses the line.
Setpoint watches your temperature around the clock and alerts you the instant it breaks a threshold you set — over Wi-Fi, straight to your phone. No hub. No gateway. No subscription to read your own data.
Why Setpoint
Monitoring built to be trusted, not babysat.
No hub required
Talks to your Wi-Fi directly. Nothing extra to buy, plug in, or keep alive on your network.
Threshold alerts
Set a high and low limit per probe. Cross it and Setpoint tells you — the moment it happens, not on the next poll.
Own your data
A dashboard you run yourself. Per-probe min / max / average, full history, one-click CSV export.
Weeks per charge
A protected 18650 and deep-sleep firmware. Recharge over USB-C; a power switch stops shelf drain.
How it works
From probe to alert in three steps.
Place the probe
Drop the waterproof stainless probe wherever temperature matters — a fridge, a tank, a room, a rack. Add a humidity sensor on the expansion header if you need it.
Join your Wi-Fi
Power on and connect in the browser — no app-store download to get started. Setpoint remembers the network and reconnects on its own.
Set the line, walk away
Choose your safe range. Watch it live on the dashboard, and let the alerts do the watching when you can't.
