[BUG] Roborock 10R (Saros) not working with adapter – “wrong final block length” & local LAN key unavailable
Bug Description
Since switching to the new Roborock 10R (Saros), the ioBroker.roborock adapter (v0.6.18) no longer works.
The adapter starts, MQTT initializes, but as soon as local data is received, the adapter crashes with a crypto error:
Error: error:1C80006B:Provider routines::wrong final block length
at Decipheriv.final (node:internal/crypto/cipher:193:29)
at localConnector.decryptECB (/opt/iobroker/node_modules/iobroker.roborock/lib/localConnector.js:227:25)
at Socket.
Steps to Reproduce
What I already tried
- Reinstalled adapter
- Deleted and re-added the device
- Cleared Admin UI cache
- Checked the Roborock App (iOS), but the 10R does not show a developer mode or LAN key
- Tapping 10x on firmware version does not open developer options

Not sure if you loaded the latest https://github.com/copystring/ioBroker.roborock/tree/dev_ts. Your log reports dock type 16 is missing. I have added dock type 16 yesterday. Please reload the version and try again.
