Zkteco c3-400 homeassistant #1

Closed stepsolar closed 1 year ago

stepsolar commented 1 year ago

Would it be possible to use the C3-400 card with homeassistant ? Thank you

vwout commented 1 year ago

Hi @stepsolar, not with this library (since it is written in Lua), but I ported it to Python for this reason in vwout/zkaccess-c3-lua.

Additionally, I am currently developing a plugin for HomeAssistant. This can be found here, in my development branch: vwout/home-assistant-core/tree/add-zkaccess-c3-integration/homeassistant/components/zkaccess_c3

When you copy the folder zkaccess_c3 and its contents to the custom_components folder of your HA installation, you can add a C3 panel via the ‘Add Integration’ wizard.

The integration is brand new, so might contain issues and limitations. Let me know what you encounter (but please create issues on my home-assistant fork :P).

stepsolar commented 1 year ago

Thanks a lot, I'll try it tomorrow and let you know how it works. For me the main function it serves is to be able to open the door, but I have already understood that it does something else as well.

stepsolar commented 1 year ago

Hi, sorry but I can't contact you in other ways, I have a problem I copied the zkaccess_c3 folder to custom_componed I restarted but I can't find anything in the 'Add Integration' wizard. What am I doing wrong? Thank you

vwout commented 1 year ago

When you installed the folder zkaccess_c3 to config\custom_components and restarted HA that part is correct. When restarting, the log should state: "[homeassistant.loader] We found a custom integration zkaccess_c3 which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant".

You log probably also has this error: "[homeassistant.loader] The custom integration 'zkaccess_c3' does not have a version key in the manifest file and was blocked from loading. See https://developers.home-assistant.io/blog/2021/01/29/custom-integration-changes#versions for more details", which is because my development is created as 'core component'.

To make this work as custom component, add something like "version": "0.0.1", to manifest.json, e.g.:

{
  "domain": "zkaccess_c3",
  "name": "C3 Access Control Panel",
  "version": "0.0.1",
  "after_dependencies": ["network"],
...

Hi, where do I enter the IP and password of the C3-400? Screenshot_2023-06-22-20-24-06-813-edit_io homeassistant companion android

vwout commented 1 year ago

Right, I guess labels are missing since I don't have translations yet (except English). The order of input items are:

I don't know yet how password authentication is handled on the device. So there is no field to set a password yet. Would you be in the position to either remove the password, or Wireshark the communication with the panel while connecting to it from one of the ZKTeco tools?

stepsolar commented 1 year ago

With the zkteco software I can change the password I don't think I can delete it, I'll try tomorrow.

stepsolar commented 1 year ago

This project doesn't work for c3-400 but I noticed they put password for setup, hope it will help for your project https://github.com/icarome/zk_teco

vwout commented 1 year ago

Thanks, I will have a look, set a password and try this on my C3-200. When it works, I will add it to this library and use that in the HA component.

stepsolar commented 1 year ago

hi, i removed the password from the c3-400 i tried your project entering ip, port, and name i click enter but nothing happens, configuration example:

Am I writing it correctly? Thank you

vwout commented 1 year ago

Looks good to me. Do you have a Python environment (>3.7) or Docker available?

What is the result when you clone this repository (zkaccess-c3-py) execute the command C3_GetDeviceParam.py 192.168.2.205?

stepsolar commented 1 year ago

I think I can use Python as well if I don't know it well. I know Docker but it is not installed in my machine where homeassistant is installed. But why in homeassistant the configuration is not successful? The card works correctly with the zkteco software that I have installed on my Windows PC.

vwout commented 1 year ago

I don't know why HA is not working, also the plugin is not verbose on its logging. The HA component uses my zkaccess-c3-py library. The command C3_GetDeviceParam.py outputs all traffic as part of debug output, which might provide a hint regarding why its not working.

I at least discovered that the authentication is different than the ZKT (ZEM*) panels supported by the library of fananimi/pyzk.

stepsolar commented 1 year ago

on the linux machine where homeassistant runs I installed "zkaccess-c3-py" the result is below, now how do I run the commands? I'm no expert but I'll try. Thank you

That's quite a fundamental error. Two questions:

stepsolar commented 1 year ago

firmware version AC Ver 4.3.4 Apr 27 2017

stepsolar commented 1 year ago

I don't quite understand the second question, what should I do?

vwout commented 1 year ago

I don't quite understand the second question, what should I do? Forget about it :)

I did some additional testing with ZKAccess 3.5 desktop software instead of the ZKAccess 5.3 web interface. I modified the session initiation and added password support in a9dbed871ef1eae9f84b0512bd744f35aefe84f4. This updates are not released to pypi, but only committed to this repository. If you clone the repo, I'm curious to see whether C3_GetDeviceParam.py works on your device now.

stepsolar commented 1 year ago

I cloned the entire c3 folder in /usr/local/lib/python3.9/dist-packages/ I reboot

vwout commented 1 year ago

Ok, that's unexpected. The only way to get to know how it is supposed to work is to capture the traffic between the ZKAccess application and the C3 panel.

A way to do that is to install Wireshark. When capturing traffic, you can filter the traffic to the panel with the expression ip.addr == 192.168.2.205 (see e.g. https://www.redhat.com/sysadmin/introduction-wireshark). You can export the traffic via File->Export Specified Packets. Be sure to apply the filter, otherwise you will share all you network traffic :) Oh, and if you apply a password, don't set one that you want to keep secret, since it'll be exposed in almost plain text.

vwout commented 1 year ago

Thanks! Your C3 seems to use a variant of the protocol. I'll have a look on how to include this in the library.

vwout commented 1 year ago

Your C3 does not seem to use sessions (a session id and a message counter). Commit 1208713b8e1282c122d448f2e6e3764aadd1d43b implements at potential solution. I can't test this since my panel does not accept this (I'm on firmware AC Ver 4.1.9 4609-03 Apr 7 2016, so not that much different). Maybe this works :crossed_fingers:

stepsolar commented 1 year ago

How do you like the result?

vwout commented 1 year ago

I like it a lot, it means the solution works. I only missed handling of data without session, which has been corrected in c84ba3723c321f3b4095ebfcaf1f3330a1677131.

stepsolar commented 1 year ago

i'm trying to understand the changes you made to your code but i'm having a hard time, from wireshark how did you find CONNECT_SESSION_LESS = 0x01? now on homeassistant it should work?

vwout commented 1 year ago

now on homeassistant it should work?

Not yet, I first need to release this library in PyPi. I'll do some cleaning up and release it soon.

Regarding my changes: The message send to the C3 panel (according to the protocol described in https://github.com/vwout/zkaccess-c3-py#protocol) differs between the different panels. My panel corresponds to what I described in the readme so far. The ZKAccess software send the following command:

aa 01 76 04 00 fe fe fe fe 46 77 55

This is a startbyte (aa), version indicator (01) and connect command (76) followed by the data length (4) and data (fefefefe), with finally the checksum en stop byte. The response to this command is a reply that contains a session id, in this case 05d8 (in little endian encoding):

aa 00 c8 04 00 d8 05 fe fe a3 09 55

What I see in your traffic log is that the ZKAccess software sends a different command to start a 'session':

aa 01 01 00 00 50 3c 55

The command is 01 instead of 76 and no data is send with the command. The response from the C3 panel also does not contain any session identifier, just the command acknowledge (c8) and no data:

aa 01 c8 00 00 80 02 55

When I try command 01 on my panel it accepts it, but further commands fail without session data. So what the library does now is attempt to initiate a session and when it fails try a connection without session.

stepsolar commented 1 year ago

Hi, I have seen the updates. I also downloaded everything on homeassistant, which now lets me complete the configuration but the identities are all unavailable. What can I do?

The errors show that no (or incomplete) data is received:

if data[-1] == consts.C3_MESSAGE_END:
~~~~^^^^
IndexError: index out of range

That fact that it crashes on that is a bug, I will fix that, but it does not resolve the issue. The connection between your homeassistant installation and the C3 panel is lost (BrokenPipeError: [Errno 32] Broken pipe). Is there a WiFi connection between the two?

I will improve the connection handling, but if the connection is bad, it will not give very good results. Do you have earlier logs fro HA, e.g. directly after startup? I would expect either the entities to be created, or an error to be logged.

Regarding you message dump, please upload the pcap log, this way the data is not easily readable and your selection starts in the middle of a session, so is incomplete.

stepsolar commented 1 year ago

Entities are created, but are unavailable. The connection is not on WiFi.

stepsolar commented 1 year ago

now works

vwout commented 1 year ago

Thanks for the confirmation, great that it works!

I will look into the root causes for the errors you noticed, it might also be that the session-less connection of your C3 triggers some corner cases, that on its turn cause connection drop-outs.

stepsolar commented 1 year ago

In homeassistant I still received errors that I am attaching, and I noticed that sometimes the entities become unavailable and I have to reload the integration. Yes, it's great that it works, I've been waiting for a genius like you for years. Thanks for your creation. It must be inserted as an official integration on homeassistant. I will continue to follow your updates.

FYI, the custom integration has its own repo now. It can be used as custom repository in HACS. When there is broader interest, I'll add it to the default store of HACS. For now closing this issue. Just create a new issue when needed.
