The problem I have had with the Nue switches is that it took 2 different sparkies to get them installed. The first one installed a switch and thought the design wasn't safe. He reluctantly installed it, but then when he went to install it, he flat out refused to do it. Didn't like how exposed the metal of the sockets were when the face plate was removed. Then when I got the 2nd sparkie here, he didn't like them either, and was able to pull the face plate off some of the GPOs without the use of a screwdriver. His solution was to silicon them on. This created a problem when I needed to remove them to add them to the network - needed access to the reset button. Other than that, they seem to be working fine.
The switches especially have been great. I now finally have the bathroom exhaust fans come on as soon as the hot water from the shower starts, and turn off automatically. Bit thanks to the Smart Humidity Fan app from @napalmcsr.
The 2nd sparkie also said that when the heat lamp is on, that I should have the exhaust on, and also, if the heat lamp is on, the light shouldn't be on at the same time. A quick couple of rules, and now that is exactly how they operate if someone manually turns on the heat lamp, or tries to switch on the light at the same time.
