[$] The OpenSprinkler controller

The more one pays attention to the Internet of Things (IoT), the more one
learns to appreciate simple, unconnected devices. Your editor long ago
acquired an aversion to products that advertise themselves as 'smart'
or 'WiFi-enabled'. There can be advantages, though, to devices that
contain microprocessors, are Internet connected, and are remotely
accessible, if they are implemented well. The OpenSprinkler sprinkler timer would
appear to be a case in point.
