@HA_fanatic - How was that list of known vid’s compiled and have there been any updates?
Looking at the developer docs (https://smartthings.developer.samsung.com/develop/guides/manifest/requirements.html), it says this about mnmn:
Each manufacturer is identified by the string mnmn, for example, ab12. Manufacturers must use the manufacturer name, which was granted when a SmartThings app sync request was made as the mnmn value. If any text is used as the mnmn value, the device cannot be added to the Samsung IoT Cloud, and the device’s metadata cannot be registered on the Metadata Server. An mnmn value is given to each manufacturer and all devices manufactured by a manufacturer use the same mnmn value. Here it lists just two valid mmnm, one for Samsung stuff and one (“SmartThings”) for smartthings devices.
For vendor id it says:
ID is a text value that a manufacturer can freely assign to a device they release. Each product must have a unique VID value. For Samsung’s home appliances, TVs, and audio products, when a manufacturer has multiple product groups, they can classify the metadata of their products internally using different prefixes for VID values.
It lists how it sorts Samsung vids, but doesn’t mention anything for smartthings.
