Due to ongoing debates about the use and misuse of the “German Support” category to the detriment of users who don’t speak German, the creation of new topics on the category has been closed. Thus, this category is now read-only.
The reason for this is, that pimatic-echo assigns an unique index to every device. If you remove devices and restart pimatic, the indexes will be created again. Since Amazon uses the „old“ indexes, all devices with a missing index can’t be found anymore. I‘m planning to fix this soon, but haven’t found the right solution for this yet.
