I added such a remote control to my home automation, now I can control some devices not only from my phone, which is quite convenient.
I wrote a small review for this remote control, how and what I have now connected in my summer house, and what devices did I use. I hope this information will be useful.
I am glad that you are happy with this but for me i don't see the point of removing switches and place them all on a remote when you are automating things.
Why not just automate this with sensors and events? At home I haven't used a switch in a couple of years now.
