Hue bulbs are a safe starting point for home automation, but rather than what you could do from a solution perspective, do think about your needs first.
Thanks for the info. Just to start I think a few well placed smart bulbs might get me going for now. Then later a few smart plugs and motion detectors might be interesting.
FWIW I have had very good results with the Meross/Refoss products on Amazon that are both Alexa and HomeKit compatible (not all of their products are, but they clearly mark the ones that are). Switches, indoor and outdoor plugs, garage door opener.
If you follow the previous link I posted it gives you the setup instructions - they use the Philips Hue Hub. That hub’s the smarts that avoid having to run processing across the devices (a lightweight mesh computing), or on someone else’s servers out on the Internet - better for privacy.
You may find that some routers or home voice assistants might have some hub-like support. I know the Amazon Echo did a while back, but I’ve been happily using my hue hub for 4-5 years now as is.
As things progress I am getting more interested in various home automation issues, such as smart plugs - video cameras etc. I am assuming this is not the best place to ask general shopping / product questions, so do you have any suggestions for varied other forums / links or sites I can go to learn about general home automation issues?
