Flashing and Configuring Laser and Motor on Nebula Star Projector CBU-BK7231N

Question

I have flashed this guy and able to control the RGB LEDs. However need to help with the config for Laser and Motor properly. The other thread in this forum with BK7231T was helpful, but I need to understand what pin 23 is doing and what value to set. The tool generated this Device configuration,...

I am glad to hear that we have a progress. Can you provide us more information on the issue, namely the chrome version and all extra details that may have affected the process? So basically, copying config from forum didn't work but typing it worked? You are using the Discovery Page incorrectly. You are supposed to paste the YAML to configuration.yaml of Home Assistant. The text field on OBK with config is for copying from, not for pasting to.

Hello, it looks like that P23 is mentioned in the JSON:


"micpin":"23",

Does your device have a microphone?

However not seeing separate toggle buttons for Laser and motor! idk what to add in autoexec.bat script!

It's normal. You haven't added script yet. Go to the Web App, LittleFS tab, press Create new file, and create autoexec.bat with the script from the thread you mentioned:
Genio Galaxy Smart Lamp - BK7231T - Teardown + Guide
Then save and reboot.

Not that I'm aware of! That raises the suspicion in my mind if there was one hidden to spy on users I will open up again and check the hardware! I added this, saved and rebooted, but still do not see the laser and motor toggle buttons! Code: text Expand Select all Copy to clipboard startDriver PWMToggler toggler_channel0 4 toggler_name0 Laser toggler_channel1 5 toggler_name1 Motor addEventHandler LEDState 1 backlog toggler_enable0 1; toggler_enable1 1;

If you still don't see the buttons from PWM toggler, please post a screenshot of your main WWW OBK page so I can check whether the PWMToggler driver is running.

Please check is there a mic connected to P23, namely, the ADC input.

soubhikkhan · Answer

Here is the screenshot Added after 8 [minutes]:Looks like 0 drivers active

p.kaczmarek2 · Answer

That's strange, are you sure that you've restarted the device?

soubhikkhan · Answer

Yes, a couple of times.. again I recreated the file with the script and restarted.

p.kaczmarek2 · Answer

This is very strange. Are you sure that your browser didn't add any special chars to the file text, thus making whitespace non-standard?

Please do a little test - go to Config, then Execute custom command (NOT short startup command), then execute:


startDriver PWMToggler

and show me again the www panel... so we can check is the PWMToggler running

soubhikkhan · Answer

OK, so after running it from the Execute custom Command, it showed OK. Then I went back to the file editor and checked every line, saved, and rebooted. Now on the WWW page, it shows 1 driver active but the toggle button is not yet visible. I tried with and without this line too. Code: text Expand Select all Copy to clipboardaddEventHandler LEDState 1 backlog toggler_enable0 1; toggler_enable1 1;

p.kaczmarek2 · Answer

If it's working from command line, but not from autoexec, it may mean one of the following:
- you haven't restarted your device so autoexec.bat wasn't run
- autoexec.bat name has a typo or a whitespace
- your browser has corrupted the autoexec.bat text whitespaces (when copy-pasting from forum) and you need to retype autoexec.bat manually, or at least manually fix whitespace
Your issue is that, for some reason, autoexec.bat does not execute properly and we need to fix that.

soubhikkhan · Answer

It worked! I moved from chrome to safari and typed everything manually! waisted hours unnecessarily!

Now there are 2 things need to fix.
1. the physical button connected to P14, toggles only the RGB LEDs. I would like to make it work in this way

single press: toggle LED
Double press: Toggle Laser and Motor

2 Home assistant MQTT.
My current config is this

mqtt:
  light:
  - unique_id: "Star_Projector_light"
    name: 0
    rgb_command_template: "{{ '#%02x%02x%02x0000' | format(red, green, blue)}}"
    rgb_value_template: "{{ value[0:2]|int(base=16) }},{{ value[2:4]|int(base=16) }},{{ value[4:6]|int(base=16) }}"
    rgb_state_topic: "star_projector/led_basecolor_rgb/get"

    brightness_scale: 100
    color_temp_command_topic: "cmnd/star_projector/led_temperature"
    color_temp_state_topic: "star_projector/led_temperature/get"

and it shows in HA like this

Based on the instructions on the other thread, I created this and pasted in the discovery tab and clicked the start button, but the laster and motor doesn't show up on HA. Also when I go to out of the discovery tab and come back, it goes back to the default setting!

My Chrome v 116.0.5845.110So this makes me believe that most probably when I copied and pasted from the forum, it may have changed some characters which was causing the driver not to load! After using Safari and typing manually, it loaded instantly. Thanks for clarifying it! So I did this but still, the buttons were not showing in the auto-discovered device! However, when I checked from the developer tab, I could see the entities. I can call them through service. It works. Hence I added manual buttons on my dashboard to control them and deleted the discovered device. What I understood is, the discovered device is coming from the OBK portal since the number of entities and the names matches with the HA discovered device. I wish if there was a way to edit and save the text field on OBK side. Added after 5 [minutes]:Also is there a way to write a script to customize the case physical button press? single press and double press?

p.kaczmarek2 · Answer

I am glad to hear that it works better now. I will check this chrome issue, but can you tell me what kind of localization settings are you using? If I may ask, what kind of language version of OS do you have? This is planned, I remember that @mnm11 requested it few days ago as well. I will take that into account. Here are autoexec examples: Search them for OnDblClick . You can also search on our forum:

Double click worked! thank you @p.kaczmarek2
