I am trying to publish to an mqtt topic on beebotte.com using a simple publish.single on my linux machine it works fine but on python anywhere I get an authentication error. There are small differences in minor version numbers, can that be what is different?
This is the code I put into the python console:
import paho.mqtt.publish as publish
mqtt_host = "beebotte.com"
mqtt_topic = "climate/set/livingroom"
auth = {'username':"token:MY_SECRET_TOKEN"}
publish.single(mqtt_topic, "python sent", hostname=mqtt_host, auth = auth)
this is the error:
Python 2.7.6 (default, Oct 26 2016, 20:30:19)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import paho.mqtt.publish as publish
>>> mqtt_host = "beebotte.com"
>>> mqtt_topic = "climate/set/livingroom"
>>> auth = {'username':"MY_SECRET_TOKEN"}
>>> publish.single(mqtt_topic, "python sent", hostname=mqtt_host, auth = auth)
Traceback (most recent call last):

and here it is working:

edit (I'm not sure if this is true):
The key is in the actual format of token:token_KxDxlcmXgQBDfWRNC (not real) beebotte.com also accepts a so-called secret key in the format of 2A4Gfgv0puYFBEVbBQX24szALcyDvMRh If I use the secret key it works from pythonanywhere (sometimes). This is leading me to beleive it is some kind of formatting problem with the : in the token.
So the question now is how to format it to work properly.
I don't think mqtt will work from a free account on PythonAnywhere. Free accounts can only connect out through a proxy using http(s) to a specific whitelist of sites. If there's an http to mqtt bridge somewhere, you could possibly use that.
