Moving into a new home
The first month is when off-gassing peaks, cleaning is heaviest, and the dashboard learns your normal. Expect noise; expect resolution.
Multi-room comparison
Two sensors tell more than one twice. The difference between rooms is often where the real story is.
Set up your Terrestream
A short first-run path: power the sensor, pair it, connect Wi-Fi, claim it to your account, then place it where the room air can circulate.
Pair with the app
Use the 6-digit passkey on the device screen to create an encrypted Bluetooth pairing, then finish the claim flow in the app.
Connect to Wi-Fi
Terrestream uses 2.4 GHz Wi-Fi. You can configure it from the app or use the temporary setup network when no Wi-Fi is saved.
