[Node-RED] Some Examples

Postby raymonvdm » Tue Apr 12, 2016 2:20 pm

I`m using Node-Red for some time now and have created some usage functions. But not all are working yet


MQTT to Domoticz (works)

Note: The data is send by OTmonitor to my MQTT broker and picked up by Node-RED to send it to Domoticz JSON interface


Code: Select all

MySQL to Domoticz (issues)

Code: Select all

The problem is that the flow gives me the following output and not only the value

Code: Select all
[{"":6531}]

"payload": 18.19,
"payload": [ { "": 6531 } ],

I have added two change nodes, which seem to do the trick

Code: Select all

msg.payload
Search for [{"value":
Replace with

and

msg.payload
Search for }]
Replace with



But now i need to find a way to add 3 extra digits behind the payload to fix a issue with domotigz
