I have the RFToy and used it to decode a remote socket, but could not get opensprinkler to control it. Have you tested any of the Sonoff devices ? There seems to be a lot of neat stuff, and I’d like to be able to use them with opensprinkler as my hub. I don’t like the idea of having Sonoff software on my phone or in my network phoning home to China, I’d also rather not buy a hub just to do this work.
Something like this to control landscape lights …
