Wiegand WG26 Four Door Access Controller - AKA WGACCESS, UHPPOTE, WG2004

[TFay]

I have mapped out the basic controls for the Wiegand WG26 four door access controllers commonly found on Amazon, etc., under the brands such as UHPPOTE and WGACCESS, and is known as the model WG2004 (which all use the same software from www.wiegand.cn).

These use standard Wiegand WG26 keypad/RFID controllers and can be integrated with an ISY/Polisy environment via network resources to control the doors. I use a WG2004 for my front gate entry and exit, along with my garage door. I also plan to integrate Door 04 to trigger unlocking my Kwikset Zwave lock via a contact closure monitored by the ISY. These devices are also commonly used for access control for commercial buildings, etc., as they use keypads which do not provide direct contact closures to open the door, but send a serialized code via WG26 protocol to the central controller, which then validates the access granted to the keycode or RFID code, opening the door controls from relays located on the central controller board. Integrating these with your ISY/Policy is a way to use keypads and RFID, as well as control from your ISY via any other method you devise. 

Note on Authentication: The WG2004 does not use standard authentication, but rather uses a login via an HTTP POST/PUT command into the username and password text what are meant to be the GUI text input fields. As a result, you must always use the login network resources first, followed by the network resources you wish to activate, such as the door control. For example, an ISY program to open Door 01 from the WG2004 would first call the network resource "WGAccess_Wiegand_WG26_Control_Login" (which serves as the authentication for the session) and then "WGAccess_Wiegand_WG26_Access_Control_D01" which issues the actual command to open Door 01. 

Change your Password: The body of "WGAccess_Wiegand_WG26_Control_Login" is set to "pwd=abc&body=123" assuming a username of "abc" and password of "123" (which are defaults for the WG2004). Once you set your own username and password on the WG2004, please update them in the body of the "WGAccess_Wiegand_WG26_Control_Login" network resource. 

Note on assigning users to the WG2004. 

Users can be added to the WG2004 via WGACCESS software from www.wiegand.cn, or from the web GUI on the WG2004. Using the examples provided here, you could also likely create network resources to add/remove users from the WG2004 via the ISY (or more likely the Polisy), but I have not had the need to delve into that yet.

Any idea if these Weigand devices can use cellphone NFC communication to activate a door, instead of the RFID tags?

Possibly on Android, but make sure you have the right frequency reader to match your phone's capabilities. 

I tried on iPhone and gave up, as Apple seems to have that functionality locked down. Instead I carefully cut a thin RFID card into a circle around the coil, and then gently sanded it down as thin as I could without damaging it, then placed the RFID on the inside back of my iPhone case. Work great! No app required.
