Yes I have that module for the RKL. I get into it by port forwarding. It is 4/10 because it's much slower to load than apex's web page. There are a couple apps for it. The older version doesn't work at all. The newer one is also just 4/10 compared to all of neptunes apps. The one big limitation is you cannot change setting remotely, just monitor, last time I had the inclination to check.
I only comment on equipment I own. I have the RK2, RKL & RKE and most modules.
