UPDATE 31.10.: Amazon Alexa - ioBroker Skill läuft aus ?

Hello,
I am integrating 7 devices into Homekit via the Yahka Bridge.
This works sometimes 2 days, sometimes 2 weeks without a problem.
Then the bridge can still be found in Homekit, but no connection to the devices.
So far I have only ever been able to delete the old bridge, change the username in the Yahka instance, add the new bridge and add the devices again.
Does anyone know the problem or is there another solution?
