Since this affected the weather service, no updates are needed on your part as the weather service has already been patched.
Also, if you notice the code changes, 2.1.6 will be adding an “Auto Rain Delay” which is a direct equivalent of my PHP based code which applied a rain delay that’s user configurable if it is raining. This is also similar to the OSPi plugin that I started. This allows the user to have weather based rain delay without affecting the watering level. We will announce this with 2.1.6 in the coming weeks.
