HCS012 FAQ

Pairing Steps:
Open the app, select "Add Sub-device" → "Rain Gauge" to enter pairing mode (the app will start a countdown).
Before the countdown ends, install the rain gauge’s batteries to complete pairing.
Note:
Ensure the hub is in pairing mode before powering on the rain gauge.
Keep the rain gauge close to the hub during pairing.

• Check if the tipping bucket’s protective tape is removed:
  Open the rain gauge cover and remove the fixing tape from the tipping bucket.
• Check for mechanical issues:
  Ensure the tipping bucket is not stuck. Manually adjust if needed.
• Check distance & interference:
  Place the rain gauge closer to the hub (avoid thick walls, glass, or electronic interference).
  Most issues are caused by weak signals.
• Test for hardware failure:
  Pour water slowly into the funnel (or manually tip the bucket).
  Wait 3 minutes to see if rainfall data updates in the app.

• Verify bucket flips match reported data:
  Each tip = 1mm rainfall. Manually flip the bucket (e.g., 10 flips = 10mm) to test.
• Ensure proper installation:
  Check if the rain gauge is level (adjust using the built-in bubble level).
• Calibrate if needed:
  If the error persists, manually measure rainfall and calibrate in the app (±20% range).

Delete the device in the app to clear historical data.
Reinstall batteries carefully:
Secure the tipping bucket with tape before reinstalling batteries to prevent false readings from movement.
