# Package: Kogan Kettle MQTT Control
# File:    kogan_kettle.yaml
# Version: v1.0.0
# Date:    2022-10-11
#
# Purpose:
#   Provides kettle temperature monitoring, power control, and selectable
#   keep-warm temperatures through a Tasmota/TuyaMCU MQTT interface.
#
# Behaviour:
#   - Reads temperature data from the kettle's TuyaReceived MQTT payload.
#   - Controls kettle power through its MQTT power command topic.
#   - Maps the keep-warm selector to the kettle's TuyaSend4 commands.
#
# Dependencies:
#   - Home Assistant MQTT integration and broker connectivity.
#   - The configured Tasmota/TuyaMCU kettle MQTT topics and payload structure.
#
# Known Limitation:
#   - P013-F026 records that temperature parsing assumes a fixed nested JSON
#     payload. Malformed or unrelated messages may cause template errors.
#
# Version History:
#   - v1.0.0 (2022-10-11): Initial kettle monitoring and control package.
