It’s been several weeks that the rain sensor and code have been in place, and we have had rain on and off, so I thought I would follow up with some data on the Toro wireless rain sensor. The unit seems to be quite reliable. I’m running a cron job every minute on the OSPi machine and logging to a remote system.
zcat -f `ls -1tr /var/log/ospi*` | grep -i raining

As you can see the sensor goes on and off, and it’s raining now. I have the unit set at 1/4″ so it’s pretty sensitive.
For reference, this is the one I’m using.
