I've been doing a quick bit of research into Zigbee. It does sound like it might be a viable solution. It's secure, low-power, open-standard etc. I had been ignoring Zigbee because the modules I was aware of are quite expensive (>£20: i.e. would double the cost of the TRV) but there are some ZigBee modules on Ali Express for $7.20. That module is based on TI's CC2530 chip which is not just a ZigBee radio but also an MCU with 8KB of RAM and 32-256KB of flash (the Arduino has 2KB RAM and 32KB flash). i.e. I think that $7.20 module is all you'd require for the "brains" because it's both the radio and the processor.

(This seems to be an 8051 CPU inside.)
