Who could change a binding (java coding)?

Hi folks,

is there someone who has time and interest to change some java coding of a binding? Shoko made a binding for the ETA heating system which does not fit to my ETA model but I’m not able to program the changes. I already identified what the issue might be. I strongly believe nothing difficult. The ETA binding is not official yet, so also this process could be done later on. Thanks for every support!
