Home-Assistant and Node-RED integration with Duet

xnaron · 6 Feb 2018, 22:05

I'm trying to create some automation around my Duet controllers and integrate them into home-assistant and node-red. When I load the URL for the duet the headers contain content-encoding: "gzip" . I've tried to uncompress with gzip and have been unable to get any data. A simple test with curl

curl -H "Accept-Encoding: gzip" -I http://192.168.0.16/#
HTTP/1.1 500 Unknown message type or not authenticated

In node-red I have tried to push the http payload into a gzip node but it yields an array of char. Converting that array into a string and it is not readable. Also tried to push it into a json node but that failed as well.

Has anyone tried to do this type of integration? Any pointers appreciated.

thanks,
Brendin

 [[language]]
curl http://192.168.86.100 | gzip -d | more

Works for me.

More importantly,

 [[language]]
curl http://192.168.86.100/rr_status
 
```Returns an uncompressed JSON payload.

Remember to call /rr_disconnect afterwards or you will get old status messages in your webui

	[[language]]
	curl http://192.168.86.100/rr_status

	```Returns an uncompressed JSON payload.
