    print "Usage: {0} <channel> <value>".format(sys.path[0])
    sys.exit(1)

channel = sys.argv[1]
value = sys.argv[2]

api = xively.XivelyAPIClient(API_KEY)
feed = api.feeds.get(FEED_ID)
now = datetime.datetime.utcnow()
feed.datastreams = [
    xively.Datastream(id=channel, current_value=value, at=now)
