TaHoma error!

Yesterday after a restart of Hass.IO my TaHoma component doesn´t work anymore. I get this error in the log.

Is there anyone that can help me?

I have problem
Somfy has switched off the old good v1 API, so we have to migrate the binding to v2.
cf https://community.openhab.org/t/tahoma-binding-compatible-with-oh2/27004/342

but I can not find the sources of somfy tahoma v2

Ok, hope someone can fix it. I dont have a clue.

I found this solution:
