devices discovery is terminated without new devices about openhab-alexa

As I can't debug the official skill: Is there as well a timeout of 10 seconds and could this be extended?

Correct. The reason behind it is that the Alexa SMAPI expects a synchronous response within 8 seconds.

Based on the skill logs you provided, it seems it is taking a lot of time for the skill to retrieve your items from your OH server with potentially multiple retries. How many items, including the ones not configured for Alexa, are configured on your OH server? Seeing that you are running your server on a Raspberry Pi, there could be some performance issue depending on the number of configured items and running addons.

Is there a way to have a co-existence between official skill and private skill both pointing to myopenhab.org? (Minor if the official skill will restart working)

Unless I am missing something, I am not sure why you would want to do that. Seeing a response in the skill logs doesn't necessarily indicate that the Alexa SMAPI processed it. Based on your testing, my understanding is that extending the timeout to 20 seconds didn't help resolve your issue.

Hej,

many thanks for the fast reply. This additional information gives me the correct explanation as to why extending the timeout in my private skill does not fix the problem.
I will try to resolve the delay in the response.
I have currently 270 items in open. Already reduced them from 400+ but without any significant dely reduction.

Regarding coexistence: It would give me a handy debug option while still having control via Alexa up and running. But this is as already mentioned a minor one.

Again, many thanks for your great work and swift reply. Best regards.

It could also be that your server is running too many addons. Also look at improving the overall performance of your Raspberry Pi enabling ZRAM if you haven't done so already. Check the health of your SD card as well.

You would need to stick to one or the other as discovered devices are tied to a specific skill on the Alexa side and therefore, you would have duplicates if you want both to coexist.
