Rooms & temperature
Track how warm each room is, to help spot how heat affects how often a plant needs watering. Set a plant’s 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
This runs automatically once a day (a Cron Trigger set in the app’s code) — it logs the house temperature and every room, using the outside-temperature estimate below or a linked Home Assistant sensor, and keeps 60 days of history. “Log temperatures now” above runs the same job on demand. The first run also backfills up to 30 days of recent outside temperature so trends aren’t empty while you wait.

To use a real thermometer instead of the outside-temperature estimate for a room: add HA_URL (your Home Assistant’s 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’s entity id above, e.g. sensor.living_room_temperature.
