Wiegand interface

[golfvert]

Describe the problem you have/What new integration you would like
I am using wiegand access. It would be nice to be able to integrate this kind of equipment to ESPHome

Please describe your use case for this integration and alternatives you've tried:
At the moment, I am using a home made script. Having one solution for all would be nice.

Additional context

I think the RDM6300 uses wiegand - could you try with the rdm6300 integration?

[Zebble]

The RDM6300 seems to use a standard UART protocol. Wiegand is its own beast. It would require some interrupt-driven communication for accuracy, but does seem fairly simple.

There's a good library that can figure out the number of bits in the data automagically. If I had time, I'd port it. Any takers?

That would be very good. I have a weigand reader outside, knowing the tag read would be perfect for integrating it into Home Assistant.
Not knowing the tag I have mapped the relay as an ON/OFF, and I will have to put another rfid reader integrated for automations since I want some automation just for my tag and my girlfriend's, not for other tags.

I have a couple of Siemens AR6182-MX readers (w/keypads) that can be configure to use a Wiegand interface, would be interesting to get this hooked up to EspHome.

Tried the YetAnotherArduinoWiegandLibrary and it works on arduino but not ESP8266. Found https://github.com/esprfid/esp-rfid which uses https://github.com/monkeyboard/Wiegand-Protocol-Library-for-Arduino.git but this didn't boot on my NodeMCU board at all. Might poke more later, but in case the links are of interest ☝️

This fixes the library used in esp-rfid as linked to above
monkeyboard/Wiegand-Protocol-Library-for-Arduino#38

Unfortunately I need other bitcounts than standard depending on card type and optional pin length so I'll probably do a AR6182-MX library instead of a generic Wiegand.

@beikeland I am using esp-rfid project on my nodeMCU since a couple of weeks, just use version 1.0.2 since latest one has problems with MQTT messages for tags.

[beikeland]

My primary motivation for looking into using ESPhome was to not rely on MQTT. I've got the library working and sorted out separating Pin, Card and Card+Pin in an Arduino sketch running on a NodeMCU-devkit. So just have to wrap my head around the abstraction needed to write a new component for the Wiegand bus and a sensor or something on top of that, or find that someone beats me to it while trying to understand the ESPhome code:)

[nerdosity]

I understand that, I just replied to the fact that it wasn't booting on your nodeMCU ;)

[beikeland]

That was due to the missing ICACHE attribute for the interrupt handler in the underlying library. Fixed it.

Still trying to work out how to add the components to ESPHome, maybe one day.
Sharing a gist with the working arduino sketch for esp8266 and AR6182 reader. Reader uses an electric wiegand interface, but custom protocol.

I have a bunch of HID Prox readers, would love a component to use them with ESPHome! Currently using them with https://github.com/TomHarkness/homeID

[pricard32]

Any news on that? I've bought a keypad that use this protocol and would like to wiring it to an ESP32 running ESPHOME

[edwardscaleb9]

Also interested in using wiegand keypads connected to an ESP8266/ESP32.

Can you help me building the plugin ?
