Nope, you have everything you need right there.
Would be interesting to know how many people use the wifi feature to control it... I just set it manually and that's it.
wasn't sure if wifi would help but it is supposedly more powerful and it had a bigger discount so not too much more than the bluetooth. Only annoying thing is I didn't get free delivery and their delivery was pricy. But far cheaper straight form them than through Amazon. 120euro delivered
