Cool. Thanks for sharing. Interestingly, I also recently discovered the TP-Link N300 range extender, and was glad to see that it can act as a WiFi adapter for OpenSprinkler. One of the nice thing about the N300 adapter is that the set up procedure is much easier — it can be easily paired with any router that has a WPS button. Of course if your router doesn’t have a WPS button, you can still go through the traditional way. But the WPS feature makes it really a breeze to set up.
