Rain bucket from (J6) reading problem

Dear Switchdoc Labs

I have a problem with my Grove Weatherboard.

I connect the rain bucket from (J6) to the Grovepi board (D6) and use 12c (J3) to 12c-1.

This has caused no problems until very recently when I use the code below:


import time

import grovepi




# GROVE SENSORS

anemometer = 5 # Pin 5 is D5 Port. ----- Anemometer

rain_tipper = 6 # Pin 6 is D6 Port. ----- Rain_Tipper



grovepi.pinMode(anemometer, "INPUT") # Anemometer

grovepi.pinMode(rain_tipper, "INPUT") # Rain Tipper



while True:

try:

print("Port 5 D5", grovepi.digitalRead(anemometer))

print("Port 6 D6", grovepi.digitalRead(rain_tipper))



time.sleep(2)



except IOError:

print("Error")



For some reason D6 has started to give me a value of 1 when the rain bucket switch is open instead off 0

I have removed all external sensors and devices and so only the cables between the Raspberry Pi with Grovepi board and Grove Weatherboard are connected, and still the problem occurs, I have also replaced the cables, and tried on another Raspberry Pi and Grovepi, and again has the same problem.

I removed the 12c connections and the reading returned 0, I then reconnected the 12c and the result returned 1.

Have you any suggestion as what may be wrong?

Could weatherboard be at fault?

Note: I powered down the system when making changes.
