# Tuya Light groups setup via scenes
# Credit: https://community.home-assistant.io/t/personal-setup-vps-vpn-faster-tuya-and-more/180995

# Tuya lights respond faster if they're grouped into scenes in the Tuya app.
# 1. Create ON and OFF scenes for every Tuya light group and sync them with Home Assistant.
# 2. Create an input_boolean marking each scene on/off.
# 3. Create template light acting as a group light for every input_boolean / tuya scene pair.
# 4. Automate ON/OFF when an input_boolean is toggled.
