Awesome suggestions! Any good links / tips for those suggestions. I have a nest but was going to look at TRV's for all the radiators, as well as some nest protects. Good idea about a few iPads around the house for control too. Be interested to see what people recommend for rfid / driveway sensors (ours is a shared driveway). I haven't tried hue lights yet, only the Fibaro dimmers - but since I'm lacking in space for the dimmers to be installed that might be a good call
There is an iAutomate (I think is what it is called) plugin/forum for long range RFID - such that you could install on your vehicle(s) and trigger on a range; I have not tried it, but that is how I understand it to work.
I haven't tried any of the driveway sensors - I would LOVE to, but we get literally daily lightning storms during large parts of the year and that tends to set off the magnetic based sensors, so that's a no-go. There are a couple of IR beam ones, but I haven't tried them. There are also a couple of pressure sensors that you could install, say, walking up the steps to a porch. Search on smarthome.com maybe, but consider other sources of purchasing if they are carried locally or by Norm in the Indigo Store (not sure if he ships internationally, though).
