Great work! You can consider moving kampstrup.py to its own package and publish it to PyPI even. This way others can use it even more easily. It also keeps the home assistant parts (this repo) and the kampstrup interfacing separate.

Also, parentheses are only needed when catching multiple exception types. E.g., you can omit the parentheses on this line:
https://github.com/golles/ha-kamstrup_403/pull/56/files#diff-b42daff407aa09858d366cd76d1042a12e82de32c92ea02115b6e6dd8393bae1R141

I have thought about it, and I'm not entirely sure if I want to take public ownership of it, also because it's not really my code. But with the change I made in this PR, I agree it's pretty standalone. I'll give it another thought...

Thanks, I found a few more as well, fixed in 8192f0d

Perhaps asking @bsdphk directly helps, maybe he can give his opinion?
