README

Pot Pulse

USB-powered ESP32-C3 plant-shelf monitor for home growers to track soil moisture, light, and microclimate trends in a local dashboard without cloud accounts or automatic watering.

Motivation

Houseplant care is mostly guesswork between watering days. People often overwater because they cannot see trend data (light, moisture, humidity) across multiple pots in one place.

Target users

Home plant hobbyists with 1–20 potted indoor plants
Small office/shared-space plant caretakers
Makers who want a safe, low-voltage, locally controlled monitoring tool

Concrete use cases

Compare morning/evening light exposure per shelf position.
Track soil moisture drop rate after watering to tune intervals.
Spot dry microclimates near windows/vents before plants decline.
Export a local history snapshot for seasonal care adjustments.

Intended end-to-end workflow

Assemble device (SELV USB only) and connect sensors for each monitored pot zone.
Join device to local network (or direct USB setup mode).
Name shelves/zones in the companion app.
Calibrate moisture probes with dry/wet reference points.
Review live status + trend charts; set local reminder thresholds.
Export CSV/JSON snapshots for personal records.

MVP features

ESP32-C3 firmware with periodic sampling (moisture, light, temp/humidity)
Local-first companion web app (mobile + desktop browsers)
Per-zone calibration profiles and health-state bands (informational only)
On-device ring buffer with timestamped readings
Local network API for status/history/export
USB recovery/provisioning flow
Versioned backup/restore of settings and zone metadata

Non-goals (MVP)

Automatic watering, relays, or pumps
Any mains-voltage control path
Cloud account requirement or remote telemetry service
Plant diagnosis/treatment claims
Outdoor/weatherproof deployment

Privacy, permissions, and data ownership

Local-first by default: data stored on device and exported by user action.
No required cloud service.
