Luftdaten.info: push data to restAPI

2

I think you could work around this by setting up a reverse proxy in front of openhab (see here) but add a location block for this particular item:

location /rest/items/luftdaten {
		proxy_pass                            http://localhost:8080/rest/items/luftdaten;
		proxy_buffering                       off;
		proxy_set_header Host                 $http_host;
		proxy_set_header X-Real-IP            $remote_addr;
		proxy_set_header X-Forwarded-For      $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Proto    $scheme;
		# Change Content-type passed to openhab
		proxy_set_header Content-type text/plain;
	}

Kind of a dirty hack, but I don’t believe you can change anything inside openhab without changing the source code, and I guess it’s the same for the luftdaten server.
