Rooms & temperature
Track how warm each room is, to help spot how heat affects how often a plant needs watering. Set a plant\u2019s Location (on its Overview tab) to match a room name exactly, and its latest reading will show there.
Rooms without their own sensor use outside temperature (via Open-Meteo, no key needed) plus this offset as an estimate.
Automatic daily logging & Home Assistant sensors
To log every room automatically once a day: Cloudflare dashboard \u2192 this Worker \u2192 Settings \u2192 Triggers \u2192 Cron Triggers \u2192 Add, e.g. 0 6 * * * for 6am daily. It calls the same job as \u201cLog temperatures now\u201d above and keeps 60 days of history per room.

To use a real thermometer instead of the outside-temperature estimate for a room: add HA_URL (your Home Assistant\u2019s web address) and HA_TOKEN (a Long-Lived Access Token, from your Home Assistant profile page) as secrets on this Worker, then give that room the sensor\u2019s entity id above, e.g. sensor.living_room_temperature.
