# 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.
