It has 82 installs sharing analytics, needs the vendor's cloud and was last updated September 16, 2025. TRMNL Weather Station sends live Home Assistant sensor data to a TRMNL E-Ink display. It shows a CO₂ reading as the main gauge, plus up to six additional sensors such as temperature, humidity, pressure, wind speed, precipitation or air quality. Each sensor can have a custom display name, and a weather entity can be added to include current conditions in the data. Update frequency is set in minutes, and the number of decimal places for sensor values is adjustable. Entity IDs can optionally be included in the payload for debugging or advanced templates. It needs the TRMNL cloud, a plugin recipe added to a TRMNL playlist, and its webhook URL, and the integration is configured in the Home Assistant UI.
