Frequently Asked

Popular Questions

How long does setup take?

A few minutes: charge over USB-C, pair over Bluetooth, join your Wi-Fi, and place the probe. The Quick Start Guide walks through each step.

Do I need a subscription?

No, never. PlantSense Connect is free — the app, the web dashboard, and updates are all included.

How long does the battery last?

3 months or more on a USB-C charge. The sensor sleeps between readings — one every 90 minutes to 5 hours — to conserve power.

Which Wi-Fi networks are supported?

2.4 GHz Wi-Fi, not 5 GHz. Bluetooth is used only for first-time setup, then the sensor reports over Wi-Fi.

Does it know when I last watered?

It infers watering from the moisture readings — no logging — and estimates when the next watering is due.

Troubleshooting

When something isn't working

Connection issues

  1. Make sure your phone's Bluetooth is on and you're near the sensor.
  2. Join a 2.4 GHz Wi-Fi network — the sensor doesn't support 5 GHz.
  3. Wake it: slide the shell off and press RESTART. A 1-second white flash means it restarted.
  4. If it never shows up in the app, charge it fully over USB-C and try again.
  5. New router or password? Use Reconnect Wi-Fi in the plant's settings. Don't delete the device; that erases its history.

Calibration

  1. Moisture works out of the box, and you can fit it to each plant's soil in the app.
  2. In the plant's settings, Moisture scale: tap "I just watered: set this as 100%" right after a thorough watering, or drag the slider until the reading looks right.
  3. Advanced: Sensor calibration saves dry and wet points on the sensor over Bluetooth. Calibrate Dry in completely dry soil and Calibrate Wet in the plant's soil right after watering, never in a glass of water.
  4. Temperature and humidity need no user calibration.

Battery & charging

  1. Charge through the USB-C port under the shell with any phone charger.
  2. The small charger light is red while charging and green when full — it's separate from the status LED.
  3. Sleep is automatic: readings every 90 minutes to 5 hours is what stretches a charge to 3 months or more.
  4. Draining fast? Watch the status LED — a red blink means the sensor can't reach your Wi-Fi.

More problems and fixes are in Troubleshooting, and every LED colour is explained in What the light means.
