tl;dr; Looking for advice on how to set up lighting in my home with Philips Hue bulbs and hub in conjunction with HE and possibly smart switches.
Doing some more reading, and have decided to try out Philips Hue, so I have a starter kit on the way, with their hub and 4 Ambiance White bulbs (dimmable/with a temperature range). I'm still waiting for my HE to arrive, so will play with this 'standalone' until then.
I think the easiest way to test these out is to plug them into standalone lamps, and use the Philips app to control them. I'm confident that will work, and will give me an opportunity to move them around the house to see what sort of range I can get.
Eventually, I want to be able to control a number of ceiling lights, that either have existing dimmable wall switches, or toggle wall switches (depending on the room), but I'm still working out how best to do that.
One method would be to install smart switches in each room, assuming that I have a neutral in each wall switch that I want to control (not 100% sure yet if that's the case for all of them), I could install a smart switch in each. I think this means the smart switch would control the ceiling lights via zigbee (or z-wave?) via the HE and the Hue hub. If so, what happens if either hub goes down for whatever reason? Would the smart wall switch still be able to turn on or off the ceiling lights? My guess is no.
Second method, if I'm stuck with the existing mechanical dimmers/toggles because I don't have a neutral in each switch box... In this case, it seems to me that I'd want to tape over the mechanical wall switch to disable it, as turning the light off - or dimming them - would cause power to be cut to the smart bulbs in the ceiling fixture, causing loss of control to them until the switch was flipped back on, and they reconnected to the HE and Hue hub (assuming they do - I've not played with either hub yet!) Controlling the lights in this manner would require any of either a philips remote, a smartphone app, or HE logic based on time of day or room sensors, etc.
My preference would be to try and keep costs down (i.e. not have to replace all my wall switches with smart ones) unless necessary, but I also need to make sure that the lights work 100% of the time regardless of the state of either hub.
Looking for advice from folks who have done something similar.
Thanks in advance!
