Pump a sine way into a influxdb database
#!/usr/bin/python
# A little script to send test data to an influxdb installation

USER = "user" # The influxdb user to authenticate with
PASSWORD = "password123" # The password of that user
TIME = 1 # Delay in seconds between two consecutive updates
STATUS_MOD = 5 # The interval in which the updates count will be printed to your console
n = 0

Hi Thom,

I downloaded this Py script but it looks incmplete. I'm no Python programmer but I can see the end to the for loop?

Have I missed something?

Hello,

the end of the loop is implicit, python syntax is based on indentation

Hello,

Your title reads Pump a sine way into a influxdb database.
The word way should be wave.

Why sleep for so long? Will we break something on the influx side if we try to insert too quickly or something? That seems like a huge problem if so...
