JSON and XML via http server
Measured values can be obtained by HTTP GET requests sent to http server
running at WiFi sensor at TCP port 80. Values can be provided in XML or
JSON format via files values.xml and values.json. Feature is independent on
device security. From this reason is feature disabled by default. To be able
utilize this feature, it needs to be intentionally enabled at device setup. When
feature is disabled http error code 403 is returned. Python examples how to
get values via XML and JSON file are available at About / Library section of
webpages.
Responses to GET requests to files values.xml and values.json at port 80
are served by the http 1.0 server with single TCP socket capability. Response
time depends on WiFi signal strength and load of http server. Average
