Tuya blinds

LocalAssistant talks to each blind directly on your network with the Tuya local protocol, encrypted with the blind's own local key. The Tuya cloud is only needed once, to read that key.

#Get the device ID and local key

1. Create a free account on the Tuya IoT Platform.
2. Cloud, Development, Create Cloud Project: any name, the Smart Home development method, and your data center (Central Europe for an account made in France).
3. In the project, Devices, Link App Account, then scan the QR code with the Smart Life or Tuya Smart app the blinds are paired with. Every device shows up with its Device ID.
4. Cloud, API Explorer, then Device Management, Query device details with a device ID: the answer's local_key is the key.

Re-pairing a blind in the app gives it a new local key: copy it again.

#Add it

Devices, Add a device, Tuya blinds, then Add the blind: a name, the blind's IP address (reserve it in your router), the device ID, the local key, and the protocol version. Most blinds speak 3.3; newer ones 3.4 or 3.5, shown as version in the device details.

A blind's Edit changes its address, protocol version or local key later. If the position reads backwards (closed shows as open), check It reports 100% when closed there.

#What it uses

The standard Tuya curtain functions by default: data point 1 to open, close and stop, 2 to set the position, 3 to read it. A blind that reports "Position unknown" or ignores commands uses others: the Data points fields of the add and edit forms take them, from the device's functions in the Tuya IoT Platform.
