ThermalTrace vs WeatherFlow Tempest
A Tempest on the roof tells you outdoor air, wind, and rain with excellent fidelity. Pipes freeze where the water is, usually a garage, crawlspace, or shop the station never sees. Use Tempest for yard weather and ThermalTrace for the indoor probe that sits by the plumbing.

Frequently asked questions
Straight answers for people comparing ThermalTrace to WeatherFlow Tempest.
Does Tempest replace an indoor freeze probe?
No. Tempest measures outdoor yard weather. Pipe freeze risk lives indoors (garage, crawlspace, shop). Use Tempest for outdoor context and ThermalTrace for the probe by the plumbing.
Can I use both Tempest and ThermalTrace?
Yes. Many households keep Tempest for weather and ThermalTrace for space temperature alerts where water actually sits.
Will outdoor air alone catch a garage freeze?
Not reliably. Garages lag outdoor air and can freeze while the yard looks milder, or stay warmer while outdoor air plummets. Probe the space.
