🌐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.

1. Short pin D15 to GND

3. LED blinks 3 times 🔴🔴🔴
4. Remove the short after the 3rd blink
5. Device reboots → access point mode restored
