RC522 readers are far more prevalent than PN532 readers simply due to cost. There is not current support for them in Tasmota

I have made an RC522 work at its most rudimentary level by hacking into the PN532 ino. It works, but its obviously not clean and I have to compile my own BIN for this project. Perhaps someone with more time/skills can take this further or pretty it up so it is more acceptable to the main code base

This can be renamed .ino to use and just plug it right in and you have to also add the MFRC522.h library to the build.

Its only function right now is that when you scan an RFID card it will report out in the console the number of this card in the sensor data. It is formatted along the lines of tele/CardSwipe5/SENSOR = {"Time":"2020-11-19T07:20:53","PN532":{"UID":AFF2BA}} It works for my purposes but is rudimentary and an admitted complete hack. Someone else can do better

One additional bit of info. I am trying to get an entity recognized in HA for this hacked sensor routine. I try to follow the expected syntax that is documented for the PN532 sensor as shown below from the Console

MQT: tele/Cardswipe6/SENSOR = {"Time":"2020-11-20T08:38:50","PN532":{"UID":"77B0A65F", "DATA":"ILOVETASMOTA"}}

The New Tasmota(Beta) 9.10 Integration inside HA picks up my V53l0x, my PCF8574 output, but will not see this RFID no matter how I seem to format the MQT messages.

Now I realize that my expectation that any of this should work is ZERO. But if its something simple, I'd love to get it working.
Being clueless about this, can anyone perhaps provide insight into what is needed for an auto integration via Tasmota inside HA ? Why does it correctly set up the V53l0x sensor which is integrated in much the same manner

MQT: tele/Cardswipe6/SENSOR = {"Time":"2020-11-20T08:44:50","VL53L0X":{"Distance":9999}}

That above works perfectly.

I even tried paring it down to this

MQT: tele/Cardswipe6/SENSOR = {"Time":"2020-11-20T08:38:50","PN532":{"UID":"77B0A65F"}}

No go.

Hi
At this moment the reader work but antena range it is low.
Do you think Is it possible to add SetOptions to set antenna gain value RFCfgReg 48.
thank you
