Setup

This component supports config flow, so you can either configure it in configuration.yaml or add from frontend "Configuration -> Integrations"

YAML

switch:
  - platform: localtuya
    host: 192.168.10.122  # (required) ip addres of the device
    local_key: !secret local_key  # (required) local key of the device
    device_id: !secret device_id  # (required) device id 
    update_interval: 10 # (optional) frequency to update the status in seconds, default: 10
    current: 5  # (optional) attribute id for current
    current_consumption: 6 #(optional) attribute id for current consumption
    voltage: 7 #(optional) attribute id for voltage
    switches: # (optional) 
      switch1:
        friendly_name: tuya switch restroom
        id: 1

update_interval is different from scan_interval, this value limits the frequency between updates of a tuya device. Default value is 10, generally 3 seconds works fine.

Frontend Integration

1. Navigate to "Configuration -> Integrations"
2. Click "+" in "Integrations" tab
3. Enter "Tuya Local" in the search box and click to start configuration
