Is your GW and PC where you running your code in the same LAN subnet (without any routers/firewalls/etc) ?
I'm asking this because it's not clear why do you configuring your FW rules

Is your GW and PC where you running your code in the same LAN subnet (without any routers/firewalls/etc) ?

GW is connected to the wi-fi network of my router. PC wich I used to test the code, I sent in the previous message, is also connected to the same router via Ethernet cable.

I also tried that example code on the notebook connected to the same wi-fi hotspot (with the gateway) and result is the same.

I'm asking this because it's not clear why do you configuring your FW rules

I just tries all possible solution that can help in my opinion.

from mi-home.

Could you please add a small pause after using and before GetDevices method like Thread.Sleep or Task.Delay for 5 seconds and check if any devices obtained from your GW ?

Tested it on my PC connected to the same with Gateway router via Ethernet cable.
Deley did not help. miHome.GetDevices() is still empty collection. And miHome.GetGateway() is still null. :(

Do you use any technologies like VirtualBox or VPN that may block UDP multicast traffic on your PC ? I saw similar symptoms in another issue #7 (comment)

from mi-home.

Also please try to run this simple python script on some device inside your LAN

import struct
from socket import *

print("Start listening socket ...")
s = socket(AF_INET, SOCK_DGRAM, SOL_UDP)
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
s.setsockopt(IPPROTO_IP, IP_ADD_MEMBERSHIP, struct.pack('4sL', inet_aton('224.0.0.50'), INADDR_ANY))
s.bind(('', 9898))
s.sendto('{\"cmd\":\"get_id_list\"}'.encode(),  ('224.0.0.50', 9898))

while True:
	data, x = s.recvfrom(2046)
	print(x, data)

You should see that data are going back and forth, if they not it means that something is blocking your UDP multicasts.
What it could be ? This is a very interesting question.
From my experience it could be everything starting from your OS network settings till router/firewall.

I had only this driver

But it is already disabled.
Have no other ideas about what can block the traffic.

from mi-home.

Also please try to run this simple python script on some device inside your LAN

I tried it on my PC and Notebook.
When the script is started on PC and I start it on Notebook - 1 more log line appends on PC (last 3 lines).

When I start the new script instance on PC with an already launched instance on Notebook - log with 192.168.0.101 appends.

So, as for me, result of this investigation are:

• PC is on 192.168.0.101
• Notebook is on 192.168.0.103
• The UDP multicast connection is not blocked by anything.

from mi-home.

This logs shows that UDP traffic is blocked by something because you don't get any response

from mi-home.

This is how NOT blocked UDP multicast should looks like

There are requests and responses here from GW here
In your case something is blocking UDP responses from GW, probably non-standard OS network stack configuration

@shatulsky could you please temporary uninstall VirtualBox NDIS driver (reboot) and double check UDP traffic again ?

@shatulsky could you please change multicast addr in the python script above from 224.0.0.50 to 224.0.0.51 and run it again ?
Maybe in newer version of GW or firmware they changed multicast address.

from mi-home.

224.0.0.51

It did not help.
What about router settings? As for now, I have

The router supports 2 more modes for IPTV

Is it possible to stop firewall on your router ?

It was already disabled before I created this issue. I double-checked it, still disabled.

Have you any example of code that will simulate the multicast server. I can try to test this code on the notebook connected to the Wi-Fi hotspot and listen to it using python script, you already sent, from PC. It will help to determine on what side the problem is, network configuration or HUB broadcasting

Hello guys! I have the same problem.
After I turn off "VirtualBox Host-Only Network", the python script got useful information

Hi,

your library works with Token Aqara Gateway method or is i need to enable LAN MODE from MI app to get the Password? As you know MI app does not allow anymore to enable LAN MODE from the APP so cannot get password but this library works with UDP mode? Is my Aqara have to connected in my WIFI network to use this library? I test with my Aqara Gateway latest version hardware with wireshark and UDP i can copy but when i use Packet sender to send command via UDP nothing happens is it mean my network have no UDP allow?

Thank you.

from mi-home.

hi @fadidevv

1. This is not necessary, password is required only when you want to "send" commands to your mi home devices like "switch light on" or "turn radio on gw". If you just "read" data from your sensors, password is not needed.

2. Your application using library MUST run on the same lan segment where your GW is.
   For example if your GW has ip/netmask 192.168.1.1/255, your app must run in the segment 192.168.1.x/255

3. Not clear what do you mean by "when i use Packet sender to send command via UDP nothing happens". Could you please elaborate a little bit ?

from mi-home.

Thanks for the reply, i see your library use Multicast Traffic method like LAN MODE and you said in docs have to open MI Home app to enable the LAN mode? i tested your library in Aqara HUB v3 but not working i'm on wifi same IP of device and my computer, i try to use UDP method by using wireshark but when i send request with HEX packet nothing shows in devices nothing returns!

from mi-home.

@fadidevv could you please at first run python script mentioned above in order to check that UPD multicast traffic is working in your lan segment ?

Hi,

Nothing returns, my device gateway is paired with my WIFI HOTSPOT in the same network from where i ran this python script.

And here is the Wireshark logs same as @shatulsky Looks like Aqara Hub Gateway UDP ip has changed take a look @sergey-brutsky

@shatulsky @fadidevv it looks like that manufacturer on some versions of GW closed ports required for normal UDP multicast working.
Please check this issue --> https://community.openhab.org/t/solved-openhab2-xiaomi-mi-gateway-does-not-respond/52963/107

I found an instruction how to open required ports --> https://community.openhab.org/t/solved-openhab2-xiaomi-mi-gateway-does-not-respond/52963/114

Could you guys check if the library working after opening ports by using the instructions above ?
Thanks

@shatulsky @fadidevv guys, did you have a chance to check if the method mentioned above is working ?

from mi-home.

@shatulsky @fadidevv guys, did you have a chance to check if the method mentioned above is working ?

I tried the suggested method. But my putty output is empty.
I'm going to make a few more attempts soon. I'll keep in touch.

from mi-home.

@sergey-brutsky Nothing returns everything is empty, as i understand the new hardware models from Aqara don't work anymore with local-LAN networks i apply for Aqara Cloud and they approve my account and can only use Aqara Cloud APIS via HTTP, LAN mode only works with some Aqara devices.

I'm going to reverse the Aqara or MI Home APP and bypass the security like signatures-random in request headers and i will make HTTP APIS for Aqara.

from mi-home.

@fadidevv what is this command nmap -sU <ip of your gw here> -p 9898,4321,54321 output ?

from mi-home.

@shatulsky @fadidevv guys, did you have a chance to check if the method mentioned above is working ?

I successfully changed network.open_pf property on Gateway using this instruction. I have one more clarification that may help someone in the future. On the screenshot attached to the instruction RX and TX are the gateway connectors but not UART cable. So you should connect UART RX to TX on the screenshot and UART TX to RX on the screenshot.

After that gateway opened its ports.

nmap -sU 192.168.0.102 -p 9898,4321,54321
4321/udp  open|filtered rwhois
9898/udp  open          monkeycom

Python script receives some data -

And now I can see gateway responses using your library.
