I am planning to install the Caseta system in my ~12,000 Sq. Home. I have a tight budget of roughly ~$10,000 so I won't be going with an RA2 system. I just need to be able to turn on the lights remotely. I want to be able to have separate zones like "All lights on/off" or "Basement lights". I want to control this from my phone and alexa within the home.
What I was thinking:
I was going to do 1 smart bridge (pro?) on each floor. With the plug-in extender, that should be enough to cover each floor. (Lots of open space, roughly 4000 sq feet per floor.) If the that doesn't work, I can have 2 smart bridges on each floor, each with their own extender. I'm going to have roughly 180 switches total (most being 3/4+ way) so I am planning on bulk purchasing the dimmer packs for like 54.00 on amazon. They come with 1 dimmer and 1 pico remote. If I buy 100 packs, that should be enough to control the whole home. That will cost me around 6000.00. The next step would be to get the Homeseer S6 PRO (Roughly 1200 dollars).
My understanding is that I can connect all the smart bridges together using the HomeSeer and then group the devices like that. From there, I can use my phone or alexa to control the different scenes that I want. That way, my caseta system essentially becomes merged together and I can turn all my lights on or off simultaneously. This will help me bypass the 50 device limit and save money over the RA2 system correct?
Would this plan work well? Where could things go wrong here? I am new to this scene but I feel like this could be a good solution for what I am trying to do. I really don't need shades and all that jazz. I simply want to be able to remotely control my lights and turn all of them on/off at one time or turn a section on at one time. I want to have an echo dot next to my bed at night and I want to be able to say "Alexa, all lights off" and then all the lights in the home turn off.
Any advice is appreciated. Thanks!
