+# Inkbird ITC-306A Temperature Controller
+
+## Specs & Requirements
+
+| Item | Detail |
+|------|--------|
+| Model | Inkbird ITC-306A |
+| WiFi | 2.4GHz only — will not connect to 5GHz |
+| App | INKBIRD+ (iOS and Android) |
+
+## Setup
+
+1. Ensure phone is connected to a **2.4GHz WiFi network** (not 5GHz) before pairing
+2. Put device in pairing mode (hold button per manual)
+3. Open INKBIRD+ app → Add device → follow pairing wizard
+4. Enter 2.4GHz WiFi credentials in app — do not attempt to connect to 5GHz SSID
+
+## Known Issue — App Not Functioning After WiFi Connect
+
+**Status: INCOMPLETE — resolution not confirmed**
+
+Symptom: Device connects to WiFi successfully but INKBIRD+ app still does not function correctly (cannot control or read device).
+
+Troubleshooting steps to try:
+- [ ] Close and fully restart INKBIRD+ app
+- [ ] Check if a firmware update is available in the app
+- [ ] Try re-pairing: remove device from app → factory reset device → re-add
+- [ ] Try a different phone if available
+- [ ] Check if router has AP isolation enabled (would prevent app ↔ device communication even on same network)
+
+## Configuration (Once App Working)
+
+Set temperature probe calibration offset if probe reads inaccurately. Configure heating/cooling setpoints appropriate for the tank species being controlled.
