What is "ds.onion.io"?

[Lars Wassini]

All my Onions are connecting to ds.onion.io every 10th second.
Why? And for what?

@Lars-Wassini ds.onion.io is used by device-client that was used to integrate with the old onion cloud service. Since the onion cloud is no longer available you can remove device-client app.

opkg remove device-client

If you upgrade to the latest firmware this is no longer included anyway
