Setting up a sensor
How do I add a sensor?
Open the Grovasense app, sign in, and choose Add a sensor. Keep your phone close to the sensor. The app finds it over Bluetooth, asks which Wi-Fi network it should join, and then adds it to your account.
The app doesn't find my sensor
- Make sure Bluetooth is on and that the app is allowed to find nearby devices. If you declined, turn it on in your phone's Settings.
- Bring your phone within a few metres of the sensor.
- Check that the sensor has power: it's charged or plugged in.
Which sensor is which?
When several sensors show up, tap Blink and the light on the selected sensor flashes white for 15 seconds.
The sensor can't join my Wi-Fi
- Check the Wi-Fi password. It's case-sensitive.
- The sensor uses 2.4 GHz Wi-Fi. Most routers broadcast 2.4 GHz and 5 GHz together; if yours has a separate 5 GHz-only network, choose the 2.4 GHz one.
- The sensor has to be within range of your router where it will sit, not just where you set it up.
Using Grovasense
My sensor shows as offline
The app shows a sensor as offline when it hasn't heard from it recently. Check that it has power, that your Wi-Fi is working, and that the sensor is within range of your router. If you changed your Wi-Fi name or password, set the sensor up again from the app.
How do watering alerts work?
Grovasense watches your soil moisture readings and lets you know when a plant needs water. You can turn push notifications on or off in the app's Settings, and set quiet hours when you don't want to be disturbed.
What does the plant assistant do?
The plant assistant answers your plant-care questions in the app. You can also send it a photo of a plant. See our privacy policy for how messages and photos are handled.
Your account
How do I delete my account?
In the app, go to Settings and choose Delete account. You can also use our account deletion page. Our privacy policy explains what is deleted and what is kept.
How do I contact support?
Email [email protected], or use Contact support in the app's Settings. Include your sensor's ID (it starts with GH-) if your question is about a sensor.
