Get ready to experiment!

No documentation. The website isn't fancy either, so it was a suck and see day. I couldn't get this to work by hooking it up to an 8 channel relay board. It wasn't until I discovered that the 5v and ground on the output jack were misplaced (?) that I was able to get this to work by connecting them back to front. This meant bending the contacts on the relay board 45 degrees to make the connection. I think I could make an extension or use cords but I didn't have any. Also, as stated above, the http commands are wrong; However, I was able to map the correct commands to turn each relay on and off individually. Everything on/off worked as advertised and I was able to change the default IP address. However, once that's done, you won't be able to control it from the Sainsmart app. After further research I found that I have a version with 16 relays, there are 8 channels available (worth more!). Should work fine with the 16 channel relay board as the pins are swapped on it. However, the 8 channel version looks identical to the 16 channel version except it only has a single row connector instead of a double row, so I don't know if the pins are swapped.

Pros
