    Yes it is planned, what exactly format of data do you need, the JSON? Which fields of JSON are you actively using? If just a few, I can add it for you relatively quick, but I need a detailed specs of what you need.

    For a simple switch i need only: topic = stat/[mqtt_device]/power payload = ON/OFF (not JSON)
    stat/gosund_sp111_1/POWER = ON
    get data for a smart plug with sensor : topic= stat/[mqtt_device]/STATUS8 (STATUS8 is from tasmota but you can put anything you want) and payload JSON format like this:
    stat/gosund_sp111_1/STATUS8 = {"StatusSNS":{"Time":"2022-11-23T21:12:28","ENERGY":{"TotalStartTime":"2022-10-13T16:13:07","Total":4.865,"Yesterday":0.076,"Today":0.077,"Power": 0,"ApparentPower":15,"ReactivePower":15,"Factor":0.01,"Voltage":231,"Current":0.065}}}

    Send req for sensor data of smart plug: topic=cmnd/[mqtt_device]/STATUS payload=8

    And, if you can, i need also connection data like MAC, IP, gateway, etc topic= stat/gosund_sp111_1/STATUS5 payload = JSON
    stat/gosund_sp111_1/STATUS5 = {"StatusNET":{"Hostname":"gosund-sp111","IPAddress":"192.168.0.100","Gateway":"192.168.0.1","Subnetmask":"255.255.255.0","DNSServer1":"192.168.0.1","DNSServer2":"0.0.0.0","Mac":"C4:4F:33:F7:C4:C7","Webserver":2,"HTTP_API":1,"WifiConfig":4,"WifiPower":17.0}}
    Send req for conncection data of smart plug: topic=cmnd/[mqtt_device]/STATUS payload=5

    Thank very much!

    Qiachip Smart Switch - BK7231N / CB2S - interior, programming Good afternoon friends

    I'm starting now in the world of the smart home, it's the first time I use these devices and I don't understand much about linux but I learn quickly and I have skills to use a soldering iron.

    I bought the first GIRIER branded 16A smart plug device that came with CB2S chip but I just want devices disconnected from the cloud.

    I read several of your topics and managed to write your firmware in GIRIER which is not listed, I wanted to know where I can share photos of the connections I made successfully and help increase compatibility with your firmware and also get help

    Thanks @Ipn00tic , would you be also able to provide information where the plug was bought and how it looks like from the outside?
    If you can, you can post a separate topic here, but include more info: https://www.elektroda.com/rtvforum/forum507.html

    @kajarit can you please provide more information, at least tell me, do you see anything in OBK logs, is OBK receiving any TuyaMCU packets? Or maybe check with UART to USB converter, are any TuyaMCU packets at all sent to OBK?

    We recently also had a user on Github and everything worked for him, he just reported that tmSensor is missing a "closing" packet, but apart from that, all data is parsed correctly..

    Hi,

    I'm new in this forum and I came from Tasmota when I found out that this is the way to CB2S modules.
    I'm in a quest to re-flash the CB2S that came with my new AUBESS Power Monitor Switch.

    I've successfully flashed OpenBK7231N_QIO_1.15.125.bin using python/uartprogram.
    I've also successfully connect to the device AP, and entered the SSID/KEY pair for my WiFi. Here is where I'm having troubles.

    The device connects to one of my hotspots (my mobile hotspot), but it doesn't connect to my Unifi Wireless AP. I have no clue why. Could someone point me out a solution or a way to troubleshoot this?

    Thank you

    I've tested several releases and the issue seems to be common on all:
    OpenBK7231N_QIO_1.15.125.bin
    OpenBK7231N_QIO_1.15.60.bin
    OpenBK7231N_QIO_1.12.103.bin
    OpenBK7231N_QIO_1.11.0.bin
    OpenBK7231N_QIO_1.0.0.bin

    About my WiFi setup, it's a cluster of two UniFi AP-AC-Pro managed by a Unifi Controller.
    - SSID is being broadcasted and have no special chars besides an underscore
    - WiFi Band 2.4GHz only
    - WPA2 (some special chars on the passw like _ and @)
    - DHCP enabled (192.168.100.0/24)
    - WiFi Channel width HT20 (which is the standard) currently on ch11 (and the other AP that is far away it's on ch6)
    - NoMAC Address Filtering

    No special setup as per my understand... I've have around 20 tasmotized devices connected to this network and never had issues.

    Edit:
    Bellow you can find the logs I got from the Unifi AP where c8:47:8c:01:23:45 is the MAC of the BK7231N:

    Hello @nemec23041990 , can you provide more information about your device? What kind of sensor? Is it a TuyaMCU one?

    This might be slightly related - TuyaMCU Motion Sensor configuration: https://www.elektroda.com/rtvforum/topic3937723.html


    EDIT: You need to find dpID for temperature now.

    dpID may be 1, or 2, or 3, idk. You need to check logs.
    Then:
    Code: text Expand Select all Copy to clipboard
    
startDriver TuyaMCU
startDriver tmSensor
setChannelType 1 readonly
// link dpid to channel 1
linkTuyaMCUOutputToChannel 1 val 1


    Note that you should disconnect power wire from 3.3V pad of CB3S. Your device is a low-power battery powered device. TuyaMCU takes control of CB3S power is will turn it off most of the time.

    Hello.
    I have a similar experience with two Aubees 20A.
    Six flashed with version 1.12.44 and then via OTA to 1.15.176.
    The MAC of the two problematic ones has changed to C8:47:8C:00:00:00 and they do not connect to the router. Its logs show attempts to connect but are disconnected. Over and over again. Router reset.
    What I did on one:
    Uploading 1.0.0, 1.10.4, 1.12.44, 1.15.176 without changes.
    I padded 1.10.4 with zeros up to 2Mb with no changes.
    What else can I try?
    What could be the reason that I achieved different results with the same flashing procedure? (maybe I did something wrong?)

    Regards

    You padded with zeros, so you deleted the MAC partition - that`s logical.

    The router will always disconnect devices if you have two with the same MAC.

    According to the FAQ:
    Qiachip Smart Switch - BK7231N / CB2S - interior, programming
    Use the "Restore RF Config" tool in the OpenBeken application panel and you will get a new MAC address.

    I`m only testing one enabled device.
    I can`t access the panel because it doesn`t connect to the router. And that`s the problem :) .
    I`ll give him another router soon, maybe something will change.
    What is the most correct way to wipe the device and upload the firmware?
  • #226 20334576
    p.kaczmarek2
    Moderator Smart Home  
    It does not connect to the router because there is already one with this MAC in the network. You have wiped two devices and both now have the same MAC.
    Turn off one, repair it, then reset the router, turn on the other and repair it too.

    Option 2: if by some miracle the problem still persists, perform 5 power on/off cycles, then the device temporarily returns to AP mode, in which there will be an "Exit safe mode" button (unless you have an too old version?) and activates the Web Application and allows you to run it and from there perform Restore RF Config.

    I haven`t heard of a situation where the device wouldn`t connect at all for a reason other than what I wrote at the beginning, if you seriously have such a problem, it must be something new...

    I only do this with this one on all the time.
    I flashed 1.15.176, connected in AP mode, pressed Exit Safe Mode, waited, pressed again, Exit Safe Mode disappeared. When I press Launch Web Application, a white page appears 192.168.4.1/app? and stands alone.
    Interestingly, in AP mode, when I search for the network, bushes appear as in the attached picture.
    BK7231N downed? Maybe it has an impact that I test with a direct power supply connected? (Well, the actors had no problem with it :) )

    Web The application is downloaded from the Internet on an ongoing basis. Maybe in AP mode you don`t have a second internet connection (e.g. via cable) like me and it doesn`t load for you?

    Both the Web Application (WiFi connected to the OpenBeken AP, Ethernet cable to the router) and network scanning work for me.



    Does WiFi scanning not work on all your devices? Or maybe, for example, I don`t know, you click "Search" three times and that`s why there are bushes? This is the first time I see this, try to diagnose more and we will fix it.

    I`m not thinking about something today.
    You are right, how should the application be loaded when I am connected to the AP socket and I do not have any other Internet connection :)
    I only press once.
    There is some light. When I turn off Rel on P26, the socket connects to the router.
    Maybe when the 3.3 power supply is taken by the USB programmer, the relay wants to turn on and the voltage drops.
    I turned off the P26, plugged the socket into the 220, it connected, turned on the P26, restarted. Disconnection in the router logs :) .
    Maybe when the relay was turned on with power from 3.3, one of the elements on the board was damaged?
    It`s not a problem, I can try to check.
    I keep going.

    Do problems occur even when you power the socket from your own 3.3V source (or 5V there, if you connect it before the LDO on the board)?

    I use 3.3 from the programmer connected to the USB hub.
    I just added a 2A power supply to this hub.
    It`s the same.

    Two broken sockets brought back to life.
    What I did:
    Dump all memory from a working socket.
    Uploading this dump to a non-working one.
    After that, the socket starts in AP mode in which I changed the MAC.
    Using the Restore RF Config option causes the socket to be re-bricked, which the application warns about.
    In this case, entering AP mode does not help. The socket is unstable, it is difficult to connect to it, I only connected via mobile phone (win 10 and linux on VM with three different wifi cards)

    Good afternoon. The MK601 device cannot find contacts to control the relay. Pin 26 is a button. 24 pins are still suitable for the board, but if you put a relay on it, the relay does not respond. Also sometimes the device reboots.

    Hello @alexander21041995
    What kind of device do you have? MK601 looks like the one for toggle switch, so maybe instead of "Button" role you should "TglChannelOnToggle" role? I am not sure if I understand you...

    If your device reboots, can you try adding "PowerSave" command to short startup command? I am asking because those tiny relay modules sometimes have a very weak power supplies and running device in power saving mode wouldn't hurt. I already had similar problem and "powerSave" fixed that. Check and tell us if it still reboots.

    PowerSave command needs to be executed after device reboot. The PowerSave is not remembered, so there are two options for you.
    Option 1. Enter in Options->Short Startup Command (then reboot):

    BTW - look at the uptime! My device runs for 33 days and still stable!
    Option 2: On Web Application, create autoexec.bat:
    Qiachip Smart Switch - BK7231N / CB2S - interior, programming
    Enter command, save, and reboot (or just run should also work):
    Qiachip Smart Switch - BK7231N / CB2S - interior, programming

    NOTE: Currently, PowerSave doesn't like keeping the HTTP page open in your browser! If you leave our HTTP page - that features autorefreshing - open in your web browser, then device will not sleep much

    We are still improving it. Things are relatively hard here because there are no docs for Beken chips. It's not like ESP, where you get thousands of examples in Google.
