find_ballasts.py

[fabltd]

When running this module I get the following error:

TypeError: unsupported operand type(s) for >>: 'float' and 'int'

It appears that :
low = 0
high = 0xffffff

if response.value is True:
midpoint = (low + high) / 2

results in a value of 838607.5 (float)

Whats the fix?

I'd say

midpoint = round((low + high) / 2)

@sde1000 ?

Hi

Its a python 3 issue:

In Python 3, / is float division

In Python 2, / is integer division (assuming int inputs)

In both 2 and 3, // is integer division

[sde1000]

...and you can get the python 3 behaviour in python 2 using from __future__ import division

python-dali doesn't support python 3 at the moment. I will be fixing this before the end of November because I need python 3 support myself!

@sde1000

Thanks. I have been modifying the code to run with Python 3 and an RS232 interface.

Do you expect the find ballast process to be quite slow?

[sde1000]

Depending on the number of ballasts, yes it is slow.

Using python3 (trying to integrate DALI into home-assistant.io) and except for this all works in python3

Commit 27f8909 which I've just pushed may help with this.

If it doesn't, can you let me know how it's failing? I don't have a test environment set up at the moment; I need to buy another DALI interface...

[dgomes]

well I fixed it myself in the example code :) didn't notice there were more about it in the code.

Thanks for all your work!
