RAINPOINT HCS021FRF | Frequently Asked Questions (FAQ) · 15 questions

Q1. What does the HCS021FRF measure?

A. The HCS021FRF measures Soil Moisture, Surface Temperature, and Light Intensity.

Q2. Does the HCS021FRF measure soil temperature?

A. The current manual describes the temperature value as Surface Temperature. Keep this terminology rather than changing it to Soil Temperature.

Q3. What is the soil-moisture measurement range?

A. 0%–100% RH, as printed in the current specification.

Q4. What is the temperature range?

A. -4°F–140°F (-20°C–60°C).

Q5. What is the light-intensity range?

A. 0–200,000 lux.

Q6. Does the HCS021FRF require a Gateway?

A. Yes. The current manual specifically describes the HCS021FRF as a sub-device and instructs users to connect a RAINPOINT Smart+ Gateway first.

Q7. Can I add the HCS021FRF directly to my phone without a Gateway?

A. Direct standalone phone connection is not described in the current manual. Follow the Smart+ Gateway connection process.

Q8. Does the HCS021FRF work with a Water Timer?

A. The manual states that the sensor can be paired with Water Timers for more efficient irrigation. However, specific compatible Water Timer models are not listed in the current manual.

Q9. How far can the sensor be from the Gateway?

A. The specification states up to approximately 60 m depending on obstacles and installation conditions. Actual range may be shorter around walls, structures, vegetation, or other obstructions.

Q10. What batteries does it use?

A. 3 × AA batteries. Batteries are not included.

Q11. Is the HCS021FRF waterproof?

A. The specified protection rating is IPX5.

Q12. How deep should the sensor be installed?

A. The manual illustrates an approximately 20 cm installation hole. More importantly, the soil should cover the probe section below the MAX mark.

Q13. Can I bury the entire HCS021FRF?

A. No. Only the sensing section below the MAX mark should be buried. The upper device body and light sensor should remain exposed.

Q14. What soil types can be selected?

A. The app provides multiple soil-type options. Select the option that best matches the soil in the growing area.

Q15. Can I view historical data?

A. Yes. The app provides charts for Soil Moisture, Surface Temperature, and Light Intensity, with historical views for the previous 24 hours and 10 days.
