wrong i2c address?

[pdrobek]

Hi

I am struggling with esphome and pn532. My wemos d1 mini found i2c device on address 0x28 while yaml seeks some device on 0x24. I guess it is main issue why my pn532 was reported as Component pn532 is marked FAILED

[21:34:48][I][app:100]: ESPHome version 2024.12.4 compiled on Feb 11 2025, 21:14:37
[21:34:48][I][app:102]: Project adonno.tag_reader version 1.4

Does anyone know how change i2c address, or show different way to resolve my issues?

after change address to 0x28 :/

i2c:

• id: source
