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.

NFC tags
Each plant has its own NFC/QR link — find it, and a QR code, in that plant’s NFC tab. Tapping a tag written with that link (or scanning its QR code) opens the plant here and logs a watering automatically.
About BFCD Bud
A simple house plant tracker: log watering, repotting, sizes and care notes, tap an NFC tag on the pot to log a watering instantly, and look plants up online.

Look this plant up online
Write this link to an NFC tag (using any NFC-writing app) and stick it on the pot, or print the QR code below. Tapping the tag — or scanning the code — opens this plant here and logs a watering automatically.
NFC URL
QR code
Scan the QR code above as a fallback if a tag isn’t handy.
Writing the tag (iPhone or Android)
Using the iPhone Shortcuts app (no download needed)
  1. Copy the NFC URL above.
  2. Open the Shortcuts app → tap + to create a new shortcut.
  3. Tap Add Action, search for “Write NFC Tag” and add it.
  4. In the action, choose URL as the data type and paste the link in.
  5. Tap the play button, then hold the blank tag to the top of your iPhone until it confirms.
Any NFC-writing app works the same way — on Android, apps such as “NFC Tools” can write a URL record too. Once written, tapping the tag opens this plant here and logs the watering — no app needed on either iPhone or Android.
