Based upon what you ' ve stated , I ' d highly recommend the Lutron Caseta line of products along with the Lutron Smart Bridge . I have approximately 50 switches lights and fans all LED lights and the Lutron setup is absolutely flawless . The only two reasonable complaints I ' ve heard with this setup is the lack of a fan control I just use onoff and the look of the switches . Addressing each of your points one by one . I definitely want to replace the old switches on my wallsThis is the best option . smart bulbs are a last result unless you are looking for coloraccent lighting only . Ideally I ' d like to do the work myself , but don ' t mind hiring a contractor if I have toThe Lutron Caseta line doesn ' t require neutral at the switch which make it both flexible and incredibly easy for self installation . 3 way configurations are easily recreated by wall mounting a pico at the 3 way switch location To my knowledge no other smart lighting has a good solution for 3 way configurations . Budget is pretty flexibleGood . because no option is cheap . The Lutron line is maybe a tad more expensive then other options but worth the money by far . I want LEDs everywhereThe Lutron line is fully compatible with LEDCFL bulbs so you are good to go . Obviously want all the smart home features possible control from afar , unique settings , etc . Lutron has great mobile phone apps that allow control from anywhere , schedules , scenes , and a number of integrations with other Smart Products . It will be hard for even you to anticipate all the features you might want until you start digging in but don ' t be surprised if you run into some scenarios that don ' t pan out . it ' s just the nature of this space . Integration with other systems is key , I want the lighting to be a part of a much larger home system that I plan on building over timeAs someone who has spent 5 figures in this area testing and trying virtually every conceivable DIY setup possible . I highly recommend using your lighting as the starting point to build the rest of your system as it will likely be the most used portion of your HA setup . This will make the need for extensive compatibility much less important . I understand your sentiment wanting a broad range of integration possibilities but to date . broad range of integration in my opinion accounts for the tremendous lack of reliability in the home automation world . I would argue that reliability should be key in your decision as it doesn ' t matter how many other IOT products it works with if it doesn ' t work reliably in the first place . As originally stated . Lutron Caseta is undoubtedly the most reliable product line I ' ve ever used in the home automation world . It ' s about the only product in the home automation world that could conceivably be considered just as reliable as the dumb component it replaces . Realistically . the ONLY other consideration you should even put on the table is one of Lutrons higher end Radio RA 2 options . Nothing else out there will offer you as complete of a package with the reliability that one would expect on such an expensive investment .
