FAQs

My devices have been paired with the Tuya Smart or Smart Life app. Can they be seamlessly migrated to the Tuya v2?

  • Yes, they can. All the pairing information is stored in the cloud. For the paired devices, you do not need to go through the pairing process again. However, you need to configure the automations in Home Assistant after migration.
