Get Local Keys for your devices - iRayanKhan/homebridge-tuya GitHub Wiki

To get the local keys for your devices, you'll need an account on Tuya's IoT site. Don't be overwhelmed, there's a lot on that site but it's pretty easy to get what you need out of it. The free trial will give you enough access to the Tuya API to get the information you need, on up to 50 devices.

As a prerequisite, add all of your devices to the Tuya Smart app (iOS / Android)
