It just depends on what the device's communication interface is like.
You said it's the HTTP protocol, but you need to know what the requests
look like (e.g., what resource do you request with an HTTP GET) and
what responses look like. If things are really simple, you could use
StreamDevice. Even if the responses are real web pages, you could still
potentially use StreamDevice if you can figure out how to match on the
parts of the response that you want. This is known as screen scraping
or web scraping; it's a hack, but it could be sufficient. If it returns
a complex HTML document, complex XML document, or some nontrivial binary
response, etc., then you would want to move beyond StreamDevice and
write something (probably based on asyn) that can actually properly
parse the response.
