[OpenTRV-dev] OpenTRV to EmonCMS, via Node-RED (was OpenTRV boards)

[Damon Hart-Davis]

@ lines are incoming binary format stats messages
{ lines are imcoming JSON format stats messages

= is local stats possibly with trailing JSON

At worst you can look at the Java code we have in our concentrator that will should how to mechanically parse them

We do also have defintions of the common values written up in a few places such as the protocol discussions.

Would any of those be useful?

I assume that is the node directly connected to the Node-Red machine, The JSON blocks {"@": .... } I assume are coming from other nodes as I would assume are the @..... lines, but can someone explain the difference and point me at where I can get the info to decode these?

> Hum, I think you are getting slightly different format of messages to me :( Can you use PuTTY (or other telnet program) to connect to port 1234 on the Node-RED machine and send me the direct output? Note once connected you have to hit enter to start receiving the output.
