[BK7231T] Tuya switch with multiple buttons on single ADC pin

Question

Hi Team, I have a 3 gang touch switch from Tuya similar to '3 Gang Switch (DS-103)' in the list. I was able to use this profile to install the Open Beken using Cloud Cutter. The problem is the pin layout of the device in the profile did not work. I manually figured out the pins for WiFi LED...

It doesn't matter, I think. You can use channel 10 for button to keep it far from relays, it won't be used anyway by firmware, firmware will read ADC internally.

On the other hand, I've realized something and added a fix. Please update to latest version.

Hello, I haven't seen such a switch yet, but using ADC to handle multiple buttons is a known practice.

I can add support for such mechanism for you, I'd just need a few days.

Futhermore, can you give us more information where did you get that switch and what kind of switch model is it?

It would be also also helpful if you've checked the way resistors are arranged on ADC pins, but that's not necessary.

PS: If you want a temporary, quick solution, it should be also possible to create a simple script mechanism for that, but I don't think it's necessary.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

I will try to look into it today. Yesterday I had some work with TM1637/GN6932 driver.

Did not mean to rush you. Please take ur time.

Hello, I didn't have time to test, but I will push a test version of a driver.

Steps to setup:
1. check ADC values for buttons

You already gave me this:
no button 4095 C
1st button 1604 C
2nd button 897 C
3rd button 2 C

2. Create margins between values (as average values):

no button 4095 C
2900
1st button 1604 C
1250
2nd button 897 C
450
3rd button 2 C

3.

Set role ADCButton for ADC in Configure Module

4. Write autoexec.bat:


// start driver - always first
startDriver ADCButton
// setup map to choose button
AB_Map 450 1250 2900

// setup event handlers for buttons
// when got "no button" reading - do nothing
// addEventHandler OnADCButton 0 
// on 1st button
addEventHandler OnADCButton 1 toggleChannel 1
// on 2nd button
addEventHandler OnADCButton 2 toggleChannel 2
// on 3rd button
addEventHandler OnADCButton 3 toggleChannel 3

Tested only in simulator:

Please test and let me know if it works

I hope you know our scripting syntax.

Very new to OpenBeken, but I think I can figure this out (worked with Tasmota for a long time already). I will try this first thing in the morning (it's already 1 am). Thanks for all the help.

p.kaczmarek2 · Answer

I will be pushing it to repository in 15 minutes. Autoexec.bat can be created in Web Application, LittleFS tab.

So I tried with the latest build and the bat file. Seems to have some issues. Let me get a detailed video tomorrow. Should I use channel 1 2 3 for relay instead of 0 1 2? and leave 0 for ADC button?
