    Hi,

    Like i wrote in another post i purchased 2 parking door controllers.
    I was able to load Openbk firm finally to both of them.

    But now i have only 1 problem, the magnet sensor doesn't work.

    This is the TUYA config read with your tool from device (using webapp Download Tuya Gpio Config):

    I have updated the firm with Version: 1.17.382

    On Home assistant after a reboot, they seems to be fine:

    Screenshot of control panel displaying controls and sensor information.

    The relay (marked as 1) is working fine, but the magnet sensor (55) is not working at all

    Any help?

    This is what i'm finding at index from the device:

    Okay, let's start with your config, can you show your GPIO settings?

    Sure:
    This is the text description from Extract Config from Tuya binary:

    Code: text Expand Select all Copy to clipboard
    Device configuration, as extracted from Tuya: 
- Button (channel 1) on P6
- WiFi LED on P26
- Door Sensor (channel 1) on P8
- Relay (channel 1) on P7
Device seems to be using CB2S module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424


    Attached the 2mgs backup file .
    This are the pins used:

    I don't have any active driver, in the meantime I will play with TuyaMcu to see if I'm capable of doing something :-)

    No, there is no TuyaMCU in this device.

    Okay, so P8 is a door sensor, right? Does the sensor react to closing the door and opening it? Or, to be precise, by moving the magnet to the hall sensor and moving it away? Or does it stay same all the time?

    In original form, it was reacting.

    Now no reaction at all, but I can't see displayed anywhere, nor it's not published to HA

    Screenshot of ParkingE1 interface showing status OFF.

    It seems it's sending the binary sensor, but it's not:

    Are you really sure that there is no change on P8?
    On this screenshot, P8 is high:
    Screenshot of a configuration panel with three ports P6, P7, P8 set to high values.
    On this screenshot, it's low:
    Screenshot of a control panel showing the Open status for channel 1.

    I will ask again - is the WWW panel showing "Open" all the time? Even if you "close the door"?

    If you are really sure that it's showing "Open" all the time, then you may consider changing dInput role to,, for example, dInput_noPullUp, etc, to check various pull up options.

    This open reacts at Relay.

    The WWW panel doesn't show anything about the magnet status.

    And it was showing open because I played with commands at this post:

    https://www.elektroda.com/rtvforum/topic3936372.html#20300142

    I just reset everything and now:

    Control panel interface showing ON status.

    Only shows Toggle (relay) (pin7)

    Screenshot of the configuration panel with pin settings for P6, P7, and P8, all set to high.

    All 3 pins are high, if I change the relay value, all 3 changes to LOW, but together, it's like P8 and P7 were linked somehow.

    Added after 5 [minutes]:

    If I change P8 this way

    Screenshot of pin configuration for P6, P7, and P8 with settings and High values.

    When I use the magnet with this config, the relay is reacting, I mean, if I move the magnet to the hall sensor and moving it away the relay reacts and opens/closes.

    But I don't want that xD, I only want to show the status of the magnet sensor.

    So you configured P8 correctly now. This means P8 should be dInput with no pull up (see role name).

    The values are linked because you assigned them all to channel 1.

    If you want to separate P8 from relay, change P8 channel to let's say, channel 2, and keep relay at channel 1.

    Then they will be split. Please try.

    Ok, Finally!

    With this config:

    It's finally working!

    That's good to hear, now... now, are you aware that you need to configure this sensor for power saving? Deep sleep usage?

    Otherwise battery will drain in one day...

    Well, no problem with that, it's powered at 220V.

    No battery at all.

    Thanks!

    Ah, so you've made a modification, right? Some kind of DIY? Then please consider posting it as a DIY/guide here:
    https://www.elektroda.com/rtvforum/forum513.html
    We can also send you a free set of gadgets for submitting a DIY article, but keep in mind that for our gadget program you need to write at least some explanation, how was DIY made, why, how it works, provide photos, maybe demonstration, etc.

    Or.... by "parking" you mean a garage door controller? The one that works at 5V out of the box? Is it on our list here?
    https://openbekeniot.github.io/webapp/devicesList.html
    If it's not, then again, please provide some information, photos, etc, maybe info where it was bought, and your current config template from Web App, so we can add it to our list. Thanks.

    Our teardowns list is almost at 500 devices mark, we want to reach 500 entries soon.

    I haven't seen that model yet, so it may be interesting.

Topic summary

The discussion revolves around issues faced after flashing Openbk firmware on two parking door controllers, specifically regarding a non-functional magnetic sensor. The user provided a Tuya configuration, detailing GPIO settings and pin assignments. Initial troubleshooting involved verifying the sensor's response to magnet proximity, which was found to be unresponsive. After several exchanges, it was determined that the sensor was incorrectly configured, linking it to the relay channel. By reassigning the door sensor (P8) to a separate channel, the magnetic sensor began functioning correctly. The user confirmed that the device is powered by 220V, eliminating concerns about battery drain.
