I don’t think distance is a problem in your case. Try the following:

(with the Normally Open checkbox left unchecked)
1. Disconnect the rain sensor wires from the OSPi.
2. OSPi should now read “rain detected”.
3. Replace it with a short piece of wire between the rain sensor terminals.
4. OSPi should now read “rain detected”.

Alternatively you could wait until the next time it rains. When the OSPi fails to clear the rain detected state connect a short piece of wire between the rain sensor terminals. If doing this clears the rain detected option it could be a problem with your wiring or the rain sensor.

A couple more things; Are you sure your rain sensor is normally closed? Most are, but if you have an ohm meter its worth checking. It seems odd to me that in your step #4 you say the OSPi does not detect rain. If it is a normally closed sensor I would expect that the OSPi would say rain detected in this state (Normally Open checkbox checked). Also check the OSPi log file. At the end of a rain event it will show the runtime of the rain sensor (the time the sensor was enabled).

Hi,
I don’t know if this helps but I also have an older Raspberry Pi Model B. I successfully installed the 2.1.7 firmware without any problems. I previously had the 2.1.6 firmware installed and was able to do the update from within the 2.1.6 app. In the past I always did a git pull to get the latest update. Have you tried deleting the current firmware you have installed and updating from the repository instead of overwriting the old firmware?

Hi Rob,
This sounds like a hardware problem – possible bad RTC. I would open a support ticket.
