Temperature & RH Home Assistant Card

Bedroom temperature and humidity card for Home Assistant, powered by Mushroom and Mini Graph Card. Shows indoor trends, humidity, and a quick indoor vs outdoor comparison blurb.

Dependencies

Temperature & RH Card

Sensors to swap

sensor.gw1100c_outdoor_temperature → your outdoor temperature entity
sensor.bedroom_temperature → your indoor temperature entity
sensor.bedroom_humidity → your indoor humidity entity

Quick setup

Make sure the two custom cards above are installed (HACS is the easiest way) and added to your resources.
Copy the YAML below into a Lovelace dashboard (e.g., Manual card) and replace the sensor entities as noted.
Optional: adjust the color thresholds to match your climate comfort bands.

Tips

Adjust thresholds: swap the color_thresholds values to match your comfort ranges; add more entries if you like tighter bands.
Fahrenheit users: either convert the sensors to °C in the entity or change the thresholds to °F and the label accordingly.
Add more history: set hours_to_show on each mini-graph-card for a longer window.
Want dew point? Add another mini-graph-card and point it at your dew point sensor.
