Using nodered/mqtt to present data to HA?

roninfr · August 9, 2018, 1:48pm

Hi all,

i wanted to use nodered to read a sensor from an external OWFS server and present it to HA.
So far this is working as i can read the sensor data using a flow in nodered:

This gives me a temperature value… now i somehow need to present this value to HA. I thought of using some kind of dummy sensor which is filled with the data but i don`t know if that is working?

Or is there another way to use the data coming from the owfs server?
MQTT is also installed on that owfs server (based on rasbian lite stretch)… so i guess i could also use this one but don`t know how?

Greetings and thanks for any help!

I would just use mqtt and create an MQTT sensor in HA.

Do you happen to know how the MQTT Server can read the values of the OWFS Server tempsensor?

You would send mqtt messages to an MQTT broker from node-red

Sounds logic… Did not see the obvious!
