No smart home for me, thanks.

I don't think I'm going to set up anything that could be considered smart home tech for me. There are such fun projects in it and it would be very satisfying to be able to control some things remotely (that is, I'd decide on and be able to change the interface) but it would also be yet another never-ending project for me. I have never planned to install anything of that kind but I already have so many ideas about what I would do if I would go smart home and how I'd set things up. Let's leave it at that. I have enough too many unfinished project already.

For example I have those universal keypads that were made for numeric keypads (+ a fey extra keys) of industrial machines. I have at least a dozon of them, maybe two. They are great: Good quality in every aspect, nice hard click, sturdy, customisable (buttons can be switched out or replaced by blank covers) and a simple matrix connector. It would ne great to have one of these next to every door, in or on every table, at the bedside, and maybe one or two non-stationary ones that would control everything that could be relevant from the location of each terminal.

Every terminal would have a micro controller connected to a network. I could update those controllers all at once with new firmware. The keypads would have several modes from where I could control devices and the lights (including color, at least in one room). Also for my blinking light projects and mood light that would be a nice way of turning on and off exactly those lamps, effects and glowing pictures that I want at taht moment.

But I won't do it. That's a decision.

PS: Does anybody want some great small keypads for DIY use?

Edit: I remember that I, when I previously talked about this topic, said that I don't start with this because the value I see it bringing to my life isn't large enough. I said that the one thing that could convince me that it's worth investing money and time into smart home tech would be a really very reliable way of sensing presence in a room as well as somebody approaching the entrance to a room. Basically, if the music or podcast that I was currently playing on my PC or phone would automatically be played in the room I'm currently in but not in any room I'm not in, except when I was about to walk into another room, then I'd maybe get in. If this would be really really reliable and affortable, then I'd reconsider my decision. Thermal based motion sensors aren't good enough for this. I'd probably need a dozen of them in each room. (Looks like I saved a dozen of the wrong things from being scrapped.) And to customise the software for my home would probably a small project on its own. I don't know of another sensor that could do this that wouldn't require me having at least some sort of device on me all the time.
