Temperature & Humidity Card for Home Assistant

A sensor-only room-comfort card for Home Assistant dashboards. It combines temperature, humidity, comfort exceptions, a 24-hour range, and a compact trend without exposing thermostat or air-conditioning controls.

Features

• Temperature and humidity from ordinary sensor entities
• Clear Cold, Warm, Dry, Humid, mixed and unavailable states
• Configurable comfort thresholds
• Temperature history with minimum, maximum and sparkline
• Optional sensor battery warning that stays hidden while healthy
• Native Home Assistant visual configuration
• Responsive sizing for grids and room views
• Keyboard-accessible entity detail actions
• HACS-compatible packaging

Configuration

type: custom:temperature-humidity-card
title: Kitchen
icon: mdi:silverware-fork-knife
temperature_entity: sensor.kitchen_temperature
humidity_entity: sensor.kitchen_humidity
battery_entity: sensor.kitchen_sensor_battery
history_hours: 24
show_history: true
cold_threshold: 16
warm_threshold: 26
dry_threshold: 35
humid_threshold: 65
low_battery_threshold: 25

Only temperature_entity and humidity_entity are required. The card never requires or controls a climate entity. Battery state is displayed only when it is at or below low_battery_threshold.

Minimal configuration

type: custom:temperature-humidity-card
temperature_entity: sensor.room_temperature
humidity_entity: sensor.room_humidity

Entity requirements

• temperature_entity: a sensor with a numeric temperature state and a temperature unit such as °C or °F.
• humidity_entity: a sensor with a numeric relative-humidity state in %.
• battery_entity: an optional numeric battery sensor in %.

The temperature and humidity sensors do not need to come from the same device.
