    Thanks, didn't see that in the command list on the main github page.

    but I heard some reports that C and W may be swapped, when a Tasmota RGBCW bulb does a DGR transmit to OBK, OBK gets values swapped... is this true, can you check?

    Works fine with my OBK when received DGR from Tasmota RGBCW, no swapped colors

    Regarding SetOption65... hmm, there is an option to change default "correct boot" timer from 30 seconds down to given value, wouldn't it be enough? Or do you want to disable the "back to AP" totally?

    Is there way for me to retain the same pin settings or maybe i need to compile openbk with default pin templates similar to tasmota?
    From my understanding, I would just need to reduce the timer to prevent the reset, correct?

    What do you mean by "pin setting"? You can reduce the timer to lower the chances of unwanted safe mode. But even if it enters safe mode, you can reboot it again (after 30 seconds), and it will still remember pin settings. The safe mode does not mean that device clears it's config. It's just that safe mode ignores config for that single run, the config is still kept in memory intact.

    Here is the 30 second setting (this means that after 30 seconds after boot, the boot is marked as Ok. And if device gets more than 4 not-ok boots in the row, it goes to safe mode - to AP mode):

    So by default once it gets to safe mode, the pin configurations are reset.
    Then another reboot after 30 seconds will restore the pin settings?

    By the way, how do I enter color temperature values with DGR_SendRGBCW command?

    Some updates
    Latest firmware 1.35 (i've only start testing with wall switch starting on this version)
    Device group enabled on all devices:
    3 Gang Wall switch (N device), if mqtt payload is sent, openbk stopped responding and I have to power cycle it.
    LED bulb (N device), no issues when mqtt payload is sent, online and functioning as usual.

    Last log entry before it stopped responding.

    Not related to mqtt crash but some comments on the device groups feature

    Since the device group works based on channel number
    LED bulb is on channel 0,
    For my 3 gang switch, I assigned the relay as 1,2,3 (channel 1,2,3) .
    Turning on/off the led bulb didn't change anything with the switch.
    so I tried changing the relay to 0,1,2. Toggling relay 0 now turns on/off the LED bulb
    Is it possible to add an option that assigns devicegroupname for specific channel?

    For now I'm using this script to send on/off command based on the channel # state of the switch (changed to initial relay numbers 1,2,3)

    For my lights (N device), i noticed openbk stops receiving/sending dgr commands after some time (>8 minutes)?
    Then after an hour device groups resume working and off again. Seems a bit random but mostly it stops working and there was no dgr related logs in the log output.

    If I restart openbk, device group works again but briefly as before.

    DGR_SendRGBCW 00FF00 for green, 000000FF00 for cool white, etc. 5 hex numbers (or 3, remaining are assumed to be 0)

    DGR has been updated today and we no longer send packets directly from MQTT/TCP callbacks, we are using a queue instead - they are sent from main tick. It seems that the potential crash on power state change is solved now. More changes soon..

    Devicegroup per channel is TODO, but you can still script DGR events.

    Nice, this is for the upcoming update?

    Using http request for now as I keep testing device group,
    Can I send a channel variable on HTTP GET request? I just modified it slightly from the DGR command

    Yes, adding a different device group name on the same device (switch) would be nice

    Those are great ideas, I will look into them. I will try to support this now:

    I will tell you when it was added to the build (if I don't forget).

    The DGR was updated with crash fix, but I am not sure yet about your "DGR off for some time" report.

    Futhermore, I am just making sure you've seen it:
    https://github.com/OpenBekenIOT/webapp/pull/27
    Your pull request has accidentally so many commits, can you recheck this pull and add only the devices.json changes?

    Hmmm maybe the fastest way would be to just open a new pull request but only for that file?

    I am working on that within-string constant expansion for you, it's getting nicely. I am developing on Windows, because OpenBK now runs on Windows and it's a true gamechanger. I can add features really fast.
    Here is how my simple 'unit' testing looks in VC:

    It's still frequently happening, i just have nodered handle the automation for light groups & switches now. Just have to turn them off and re-test the device group with each new updates

    Yes, thank you, if you have any other devices for teardowns/templates, please post them as well.

    I did a short article on Device Groups yesterday, but it's not much, and not yet translated:
    https://www.elektroda.pl/rtvforum/topic3939685.html

    I am also going to extend OBK dev groups support a bit. I might include your idea with that multiple groups support:
    Tasmota Device Groups - connection of OpenBeken (BK7231T / BK7231N) with Tasmota
    Question: do other groups (second, third one, etc) need also light checkboxes? Arent they just for power? What are the use cases here?

    Another thing I am considering is doing an event handler for device group event.
    For example:
    Code: text Expand Select all Copy to clipboard
    
addEventHandler OnDGRPower "myGroup15" setChannel 1 $argument

    something like that

    Probably not required since we'll be using switch button action to send DGR command like changing brightness or colors with scripts.
    Simply assigning different group name for specific channel should be sufficient (like devgrouptie)

    p.kaczmarek2 wrote:

    +1 for this
    Do I still need to add this if I toggled channel 1 once event handler for group is added?

    Sorry, but can you be more specific? I am not sure if I understand you.

    The following code is needed when you want to script DGR by yourself, manually. Following code must be in autoexec.bat, because otherwise device will "forget" the handlers with reboot.

    When using our HTTP page to configure DGR, you don't need to script sends, they are done automatically.

    But I am not sure if that answers your question, so maybe rephrase it and I will try to help.

    @p.kaczmarek2
    sorry about that, let me rephrase
    for this event handler 'OnDGRPower'
    Code: text Expand Select all Copy to clipboard
    addEventHandler OnDGRPower "myGroup15" setChannel 3 $argument


    From what I understand, any changes to power command 'myGroup15' would toggle Channel 3 (if i turn off the lights in myGroup15, then it turns of Channel 3 of the wall switch)
    What about the opposite, does toggling Channel 3 send power command to myGroup15? Or I need to add separate script for this?

    Your use case most likely would require a DevGroupTie style mechanism.

    Anyway, multiple little issues related to DGR have been fixed in the latest commits.

    There have been some problems with colours + brightness multiple changes in a row causing the lost of brightness, it should be better now. Also some other fixes for LED driver chips like SM2135 were added.

    Looking good with recent update
    There's still the occasional DGR not broadcasting/receiving on some devices after some time even with DGR driver enabled.
    I'll continue testing those

    is DGR working stable for your devices?
    Do you mind sharing what else you might need to enable in the settings?
    I'm on .377 and it's still the same issue with no DGR events most of the time, and sometimes it just came on randomly. Tested with tasmota device and a few OBKs

    Anything else I could share here that might shed some light why it's not always working?

    I'm using DGR to link wall switches with LED strips. My wall switches has extra buttons which are not even linked to relays but they are linked to LED strips in the room which would be otherwise not accessible in an easy manner.

    I have some few more OBK bulbs but they are not used with DGR. I think I might set them for DGR just to test more.

    So far I didn't have much problems with DGR in this case. The only thing I observed is that DGR skips few packets directly after multiple reboot.

    @ferbulous , what would be the minimal circuit made from bulbs to replicate your problem?

    I've only used DGR with switch & light bulbs, i think the closest thing I have to LED strips is probably the T8 tube I recently bought.

    I have some unused BK7231 bulbs...
    What do you share with DGR, all params?
    If I just set 3 bulbs in one DGR and play with their params periodically will I manage to reproduce your issue?


    Btw I just had an idea, maybe I could make communication more reliable with one simple trick...

    When you have that strange DGR outage, does sending DGR manually via console command works? Does it drop packets at random, or is it like, it works for 30 minutes, then 30 minutes dead, then 30 minutes works again?

    Important update
    On 2023-04-29, a very rare, but still serious DGR issue was fixed that caused DGR to stop responding after a longer uptime on a crowdy IoT network. The DGR stability has been improved again. Please update your devices.

    @ferbulous , the issue you were talking about is most likely fixed now. It was caused by random UDP port assignment gradually filling a buffer.
