I bought the new one [Leviton '2nd Generation' smart switches](https://www.leviton.com/en/products/d215s-1bw) for use with homekit and extremely disappointed. From what I can see from the posts on this site, the problems I had were identical to what the first generation users had. * It took me literally hours to successfully mate. My home router (Orbi 850) does not allow the sharing of 5 GHz networks even after disabling the mesh points, decreasing the 5 GHz signal strength and moving the physical router away from the router and never managed to pair successfully. Eventually I had to "fake" the ssid / password with an old router that supports pair separation. I understand that most routers have old support for 5 GHz separation, but in 2021 it is unacceptable to ask users to handle this. I recommend choosing only smart switches that support 2.4 and 5 GHz or support the initial Bluetooth configuration. * Configuration is confusing. Holding down the power button for 4 seconds to go into pair mode or 9 seconds for factory reset is easy to confuse. The configuration user must also understand the difference between "flashing" and "flashing" to determine the configuration status. * Almost impossible to see the status LED, unless the camera is completely dark. Configuration is even more difficult. * Phone support is easily accessible, but not properly trained. * Most importantly, as many people have noticed with first-generation devices, switches will randomly lose connection over time. Some have guessed that this is related to the IP lease, but cannot confirm. I can confirm that the only resolution is to restart the switches, but Leviton does not accept the restarts, so you have to reset them from the factory and pair them again, or turn the switch over. I am very surprised that Leviton delivered this model without addressing the main issues with their device. In terms of resolution, I went ahead and returned them and replaced them with iDevices - the setup took less than 5 minutes, even with the 5 GHz network still active on my router and no disconnects in the first few days. iDevices is expensive but solid.
