## 🌐First-Time Setup
On **first boot**, the device creates a captive Wi-Fi access point:

- **SSID:** `pumpcontroller`
- **IP:** `192.168.4.1`
- **Port:** `80`

### Steps:
1. Connect to `pumpcontroller` Wi-Fi
2. Open browser → `http://192.168.4.1`
3. Enter your **home Wi-Fi SSID + password**
4. Device reboots → joins your network
5. Find its IP in your router's DHCP list

✅ That IP becomes your **pump control dashboard** 🎯

> ⚠️ If you enter wrong credentials, the device will **not** connect.
> You’ll need to **factory reset** and try again.

## 🔄 Factory Reset
1. **Short pin `D15` to GND**
2. **Power on** the device
3. LED blinks **3 times** 🔴🔴🔴
4. **Remove** the short after the 3rd blink
5. Device reboots → access point mode restored
