FAQ
First Use & Calibration
1. Do I need to calibrate the device when I first receive it?
The device is ready to use when you receive it. If it has not been used for an extended period or the readings appear inaccurate, calibrate it before use.
2. How often should the device be calibrated?
We recommend calibrating the pH value every 4–6 months and the EC value once a year. If you use the device frequently, you can shorten each calibration interval by half.
App & Connectivity
1. Why can’t my device connect to the app?
Try these steps:
1. Make sure Bluetooth and Location permissions are enabled for the app in your phone settings.
2. Restart the app and the device, then try connecting again.
3. Check that the device indicator light is flashing, which means it is ready to connect.
4. Android users: If you still cannot connect after several attempts, close the app, clear your phone’s cache, reopen the app, and try again.
2. Can the soil tester connect to Home Assistant smart devices?
No. The tester uses Bluetooth rather than an internet connection, so it cannot connect to Home Assistant. It can operate without an internet connection.
Soil Testing
1. Is there anything I should be aware of when using the product?
Insert the probe at least 2.7 inches (7 cm) into the soil. Do not test extremely hard or compacted soil, and make sure the soil is in full contact with the probe. Keep the area above the probe’s sensor dry. This area contains key components, so do not get it wet or apply pressure to it.
2. Can the soil tester be used to test nutrient solution?
Yes. Make sure that only the sensor comes into contact with the liquid.
3. Can the soil tester be used in a kitchen composter?
Yes. It can help you assess the nutrient levels in the soil produced from food waste.
Understanding Readings
1. Why does soil pH read higher when the soil is dry and lower when it is wet?
This can happen because soil moisture affects pH measurements. When soil is dry, alkaline ions such as calcium, magnesium, and sodium may accumulate near the surface, resulting in a higher reading. When soil is too wet, ions may become diluted and redistributed, temporarily lowering the reading.
For more stable results, test about 12–24 hours after watering, when the soil is slightly moist and its moisture and ion distribution are more balanced.
2. Why do readings vary in different areas of the garden?
Readings may vary because of differences in soil type and compaction. For example, regular soil and mixed soil may produce different readings. Mixed soil is often more porous and less cohesive, which can affect moisture detection. Compacted and loose soil may also produce different results.
