[OpenTRV-dev] tinyHAN application protocol and mapping to MQTT

[Mike Stirling]

Hi All,

I've been thinking about the proposed TinyHAN binary protocol and how to 
automatically map it to grown-up IoT protocols such as MQTT. I've 
committed my initial thoughts to virtual paper here and would be 
grateful for comments:

The write access is something that has been bothering me, because MQTT 
does not actually seem like that good a fit for what is essentially a 
remote procedure call.  However, the approach I've proposed on the wiki 
feels reasonable.

I've got most of what I've described up and running with a couple of 
sensors and I'm quite pleased with the result so far.
