protocol

Tuya protocol

The protocol is responsible of handling communication details with the Tuya device. Its interface consists of an asynchronous method to update the device and accepts a callback to subscribe to state changes.

Features

• automatic reconnection: commands will be queued until the connection is ready
• periodic heartbeat are sent to the device to keep the connection alive
• periodic refresh of the state (device will also send updates)
• internally, bricks are decoupled and communicate through events
