@magpern: It should never be hot. The thermal fuse should not be hot. Something is wrong with your module. About range: With module mounted inside wall (in in-wall can, below wall switch) it works fine about 10 meters from gateway. Currently I have 5 modules working well for 6 months. The only one problem I have is with poor quality Hongfa mini relays - some of these sometimes get sticky contacts and I need to remove wall switch and knock into relay. I changed relay to NPA-AS5 and problem gone. I do not know how to advice you. I suspect that there is some problem with your module - first try check why it is hot? Or you live in very noise environment.

@anticimex I can see where that is a good thing

@nekitoss Hi! Thanks for you input. CUrrently I do not have any plans to change anything on this board. Its created in Eagles CAD which i havent used since i moved to Kicad. I dont even have it installed anymore. The good thing is that all files are included so you can download and change for yourself.

@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.
