## What is Tuner4TRONIC Field?

The installation and maintenance of indoor and outdoor luminaires with NFC technology is as easy as it gets – thanks to the Tuner4TRONIC® Field app. 

The Tuner4TRONIC® Field app can be used for programming compatible INVENTRONICS NFC LED drivers in the Field via NFC (Near-Field Communication) – wirelessly and without mains voltage. In most cases, it is possible to readout the driver’s configuration even after the device’s failure. With the Tuner4TRONIC® Field app, certain luminaire settings can be easily adjusted according to the specific needs and within a predefined range set by the luminaire manufacturer. For indoor and outdoor applications, a typical example is the adjustment of the light output depending on the required application. Using outdoor drivers, the dimming levels can be changed in order to optimize energy savings and you can also disable the dimming functionality for special applications such as roundabouts or pedestrian crossings. In addition, using the copy and paste function of the app, the settings of the original luminaire (indoor and outdoor) can be easily transferred to the new one in a matter of seconds, making the luminaire replacement more efficient than ever before.

The following features are provided by the T4T-Field app:
- Adjust the light output in percentage, lumens, and milliamperes
- Edit constant lumen output (CLO)
- Adjust the automatic dimming levels, toggle dimming on/off (outdoor drivers only)
- Enter Luminaire Info (Text, GPS, QR)
- Copy and paste configurations from one LED driver to another
- Load LED driver configurations shared by e-mails
- Show a report of an LED driver’s configuration and send it via e-mail as a CSV file
- Show a report of an LED driver’s monitoring data (D4i) and send it via e-mail as a CSV file
- Open the data sheet by scanning the QR code on the driver

### 1/5 — No Connection

*2025-11-27, version 2.3.2*

NFC App does not recognize any OSRAM / Inventronics Driver.  We only work with programming tools. For mobile programming we use only LTECH, this works always and easy

### 1/5 — Sinnlos und unbrauchbar

*2024-07-25, version 2.2.37*

Leider kann die NFC Schnittstelle des iPhones nicht benutzt werden. 
Wir haben es auf verschiedenen iPhones ausprobiert. 
Bei anderen Herstellern geht deren Hauseigene Software aber ohne Probleme.

### 1/5 — No vale para Apple

*2024-02-28, version 2.2.37*

No lee NFC, sale mensaje que no sincroniza NFC con bluetooth

### 1/5 — No lee drivers por NFC

*2023-07-20, version 2.2.30*

No lee drivers por NFC

### 1/5 — Nfc movil

*2023-02-09, version 2.2.24*

Para cuando compatbilidad directa con el nfc del móvil (como hace tridonic)?

### 2/5 — NFC

*2022-07-19, version 2.2.13*

Hat es einen Grund, weshalb ich nicht die in meinem Telefon bereits integrierte NFC Schnittstelle nutzen kann (wie bspw. bei Zumthobel möglich) und ich stattdessen extra teures Zubehör erwerben soll, mit welchem ich sonst nichts weiter anfangen kann?

### 5/5 — Industry innovation!

*2019-04-11, version 1.0*

This app has no competition! Amazing!
