Two RFID Wiegand Reader

Hello everybody,
I have installed a Wemos D1 two RFID Wiegand Reader.
open gpio-0 and gpio-2
closed gpio-5 and gpio-6
If I activate it individually the RFID tag correctly assigned to open or closed,
But if both are activated the RFID tag always over open assigned, even if I disconnect gpio-0 and gpio-2.
219755: RFID: tag: 1419114678 bits: 34
219776: EVENT: open # tag = 1419114678
241154: RFID: tag: 1419114678 bits: 34
241155: EVENT: open # tag = 1419114678
The version used is release v2.0.0-dev12
is this a bug?
greetings frank

Hello
same problem at home.
can not configure two RFID devices on a wemos?
The version used is release v2.0.0-dev12

the RFID tag is connected on gpio 12/13 and it is the other one that works ?
the device 4 does not work anymore.

I'm no programmer and didn't look into the code but i assume it's same effect
as with two LCD or OLED displays.
It might be a problem that two devices use the same plugin.
The plugin can not differ between the devices.
Can any of the dev's look into the plugin and confirm?

maybe its all solved,
but this thread gave me the right hint for trying something new.
this solution-thread pushed me to tell my story:
i have a new 13.67 MHR reader "dc-9" with wiegand output.
as i wired it to me wemos d1 on gpio D3+D4 it got no reading result.
only some misterious message in the log: "bits reset 7/13/24"....
(i looked up the source, message means discarding readings with bit-count less than wiegand 24/36. i guess.
the error message could be clearer..."
i found this thread and wired the reader to D6/D7 (=gpio12/13).
i works.
mabe one has to avoid gpio 0/2 (D3/D4) on espeasy?
or only in Release mega-20181002 from 2018-10-02 ?
i did this 2 years before and it worked with different reader on different espeasy-version. but on gpio0/2 (D3/D4)...
some new feature or bug?

GPIO3 is normally used for the serial port.
Maybe this pin is also connected to a USB => serial adapter?
Or logging enabled?

yes, seems you are right:
i activated serial logging with this new device,
as far as i remember i did this not in the past.
i will check this..
i had i working today at the lab,
now i mounted all at the front-door,
now i get lots of "reset bits messages",
the wiegand is not properly read in..
i am clueless at the moment, how to fix or debug this,
appreciate some ideas..

i asumed noise on the power-supply and used my stable lab-power-source.
still "reset-bits", no stable reading.
last minute i installed a wiegand library from the arduino-IDE (this one:
https://github.com/paulo-raca/YetAnothe ... andLibrary)
and used a simple test-sketch from there on the same power-source, same reader, wemos-d1 and ports on which espeasy had no stable readings:
rock-solid readings with the sample-sketch.
maybe the timings in the espeasy-wiegand source needs improvement? or the task-timing interfere?
i dont know yet how to debug further...
next idea: i try downgrading espeasy
from: ESPEasy_mega-20181002 (normal, 4mb)
to: ESPEasy_mega-20180815 (normal, 4mb)
(i have one esp succesfull running for more than a year with espeasy build 145)

I have the same problame. On R147, the RFID reading is stable. If I use newer versions of espeasy the "reset-bits" are not maches.
