Available options depend on your version, permissions and hardware. For missing actions, see Security and Diagnostics.
Step by step
- In System > Communications, enable MQTT and set broker, port, user/password and available publish/discovery options.
- Save SmartThings client credentials, complete OAuth authorization and verify linking.
- Configure Kasa developer credentials, link the account and review discovered devices.
Options explained
- MQTT/Home Assistant
- need reachable broker; discovery helps create entities but cannot replace connectivity.
- SmartThings
- uses account authorization; review temporary personal tokens versus persistent setup.
- Kasa
- requires Internet and compatible devices; TP-Link products do not all use the same service.
- Unlinking
- can break dependent actions; inspect flows first.
Troubleshooting
For missing devices, check account, permission scope and compatibility. Keep secrets out of screenshots and exports.
