[OpenTRV-dev] Wireless protocol

[Mike Stirling]

I am putting together a table of existing protocols for reference:

https://docs.google.com/spreadsheet/ccc?key=0Aq-JTzPFIDKVdHNLVEE0Ry1oV0hvTklPRmZsZVpDdXc

Further suggestions gratefully accepted. At this stage I am also including proprietary schemes unless they are one-offs that aren't worth bothering about.

I came across "One-Net", which apart from smelling slightly abandoned, does look like it is pretty close to the sort of thing I am after at layers 1 and 2.
