On the topic of IR / ultrasound:<br><br>Any sort of occupancy detection built into the TRV would be very interesting for a future design iteration, IMHO. IR / ultrasound / CO2 (*very* expensive!) / vibration detector (microphone with low pass filter) etc.<br>
<br>In general, my hunch is that only the very geekiest folks will ever bother to explicitly program an efficient room-by-room heating schedule so anything we can do to automate the generation of a room-by-room schedule could significantly widen the appeal of the system (conditional on the system not frightening users: there's a real risk that people will worry that they're being spied on).<br>
<br>(BTW, one of my MSc students will almost certainly be doing her summer project on room-by-room occupancy prediction based on PIR and individual appliance power data: not as easy as it might first appear!).<br><br><br>

More than happy for it to go on-line.<br>
<br>
Feel free to add items as required.<br>

</div>> To this should be added other wired connections such as RS232/RS423/1-Wire for those people who have already wired their house for sensors, and/or for split TRV units in situations where a wired connection makes more sense, IMHO.<br>
