Morning all,<br />
<br />
Anyone want to help me come up with a name for an open home automation protocol then? OpenHA is gone. Totally arbitary Web2.0-esque suggestions accepted! Rough aims:<br />
<br />
- Primarily aimed at sub-GHz, so narrow band modulation and relatively low data rate. No spread spectrum.<br />
- Lightweight as possible. No ASCII strings or floating point. Definitely no IP.<br />
- Provision for battery powered two-way nodes (WoR).<br />
- Encryption and authentication built in at MAC layer.<br />
- Defined application layer profiles to aid interoperability.<br />
- Easy mapping onto existing IP based protocols (XAP, MQTT).<br />
- Radio agnostic, within reason.<br />
<br />
I did come across <a href="http://sapphireos.com/">http://sapphireos.com/</a> the other day, which looks really nice, but it is 2.4 GHz mesh based and probably still too complicated for my absolute lowest cost aspirations.<br />
<br />
IIRC most of the other suggestions that have been made so far, e.g. EnOcean, Wireless KNX, suffer in some way either from incomplete or vague specification, or a glaring lack of security.<br />
