fyi: using ebusd with mqtt and node-red to log to volkszaehler

[andig]

Hi everyone,

I've pieced together a small node-red flow that:

• pulls ebusd via mqtt
• converts the results (especially Status01 as well as pump and vent state) into numbers
• pushes the results- if updated- to volkszaehler

Any interest please let me know to add some details here.

please share the flows

Any questions/improvements please let me know. Error handling is rudimentary since I obviously know that the required channels exist ;)

this can be achieved easier now by using the new ebusd argument --mqttjson since 259f9b7

@john30 couldn't find it in the wiki and don't want to break my prod setup. Could you add json example to the docs?

[john30]

its just using "--mqttjson" additionally and then you'll get the data in json format just as by retrieving from HTTP port /data

[andig]

Sure, but what do you mean by "json format"? I'm getting a single value per channel only, what advantage does json have here?

[john30]

then leave it as it is :-)
