Hi Stephen,

The account is: [stavroslavie@gmail.com](mailto:stavroslavie@gmail.com)  
The NFC Tags are: [https://www.amazon.de/gp/product/B06XH2R5ZP/ref=ppx\_yo\_dt\_b\_asin\_title\_o00\_s00?ie=UTF8&psc=1](https://www.amazon.de/gp/product/B06XH2R5ZP/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1)

I can write anything to the tag with NFC tools, but i can’t write the scene on the ewelink app.

Thank you!

Hi there, I tested it on my phone with the V4.26.1 eWeLink app and it worked. I think maybe the NFC tag you used is incompatible with the eWeLink app due to the various types of NFC tags on the market.

Hi There,  
I found a solution. I have to write a simple text with NFC Tool first. After that its work perfectly. Here are the steps!
