Hello. It's me again with another device. This is the Avatto DMS16-W1 1-channel dimmer smart switch with CBU talking to a Puya PY32F002A (TSSOP-20) MCU.

The Puya MCU is well documented and has had some interesting followings on Elektroda https://www.elektroda.com/rtvforum/topic3946116.html

Code: Text
Log in, to see the code

CBU log out from power-on

Code: Text
Log in, to see the code

After de-soldering the CBU riser the factory firmware was dumped using Easy Flasher, attached. The extracted config was "baud":"115200".

With a multimeter I determine the following traces

so I have everything I need to capture communications between the Puya and the CBU and potentially to use J-Link to read the flash of the Puya. Sadly I was not able to get a connection from J-Link to the MCU despite my best efforts. Even with NRST-reset pulled low.

Moving onto the communication between the CBU and the Puya, TuycaMCU Analyser was a winner for capturing all I could toggle and set within the official Tuya app. Those features being:

And with the CBU rise de-soldered we can easily switch between OpenBeken and the factory firmware to recheck default behaviour by removing the Puya from the equation in this setup:

And with two USB-TTL adaptors in the mix we can capture communications in real-time when setting up OBK autoexec.

The full extent of the dpIDs being

Code: Text
Log in, to see the code

Code: Text
Log in, to see the code

I did not see dpIDs 13 and 47 in all my fiddling in the Tuya app trying every function, boot communication or tuyaMcu_sendQueryState.

Fast-forward to the current state of the autoexec

Code: Text
Log in, to see the code

which gives us

The countdown to power-on timer field numerical value will change every ~30s as the CBU receives an update from the MCU on time remaining.

This is as far as I have gone for now. Most functions appear to be working in OpenBeken, though I've not yet tested with mains power and an incandescent bulb. Certainly the communications I'm watching in the MCU analyser mirror what was seen in factory firmware.

There is one thing I don't yet know how to replicate. The brightness range, dpID3, allows you to customise the range from both ends. This is this screen in the Tuya app

The yellow indicator can be toggled from the left to right to reduce the minimum, as well as from right to left to reduce maximum. This can be seen in factory with these comms. It also involves dpID 2, I'm not sure how this can be replicated in OBK.

One thing I did notice was that although I've set the dimmer range to tuyaMcu_setDimmerRange 200 1000, same as factory, OpenBeken only displays a fixed 0-100 value range in the GUI for that channel when using the slider. It does however communicate the right values to the MCU.

suggestions for improvement welcome!

Thank you for detailed presentation. This min/max (range) control seems like a very custom component, we don't have such channel type in firmware yet, especially that it would need to handle two dpIDs... maybe, alternatively, we could just use two channels and create sliders for them? One slider called "max" and second "min"?

Of course, you can also do better UI with REST page:
https://www.elektroda.com/rtvforum/topic3971355.html

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 recently received an identical AVATTO dimmer with the designation DMS 16-Y1 instead of W1.
An interesting feature of this version is a timer that counts down the time until the light is switched off.
I tested it on a traditional incandescent bulb and it works great, I need to test it to see how it works with dimmable power supplies and LED bulbs.

What I was able to detect:

dpID Type VCnt Values
1 Bool(1) 2 0, 1 Power 0/OFF, 1/ON
2 Val(2) 18 Min=200, max=1000 Brigtnes
3 Val(2) 18 Min=10 (1%-100%), max=500 (50%-100%) Brightness range set (minimum brightness value)
4 Enum(4) 1 Switch type.: 0-Seesaw Toogle Switch, 1-Seesaw Sync Switch, 2-Kick Back Switch
14 Enum(4) 1 Power-on Status Settings.: 0-Power-on OFF, 1-Power-on ON, 2-Power-on Memory
6 Val(2) 1 Timer, seconds value

I have the same dimmer switch, only it's the 2CH model. So I see mostly things are working fine with the 1CH unit, I will try out flashing my unit and report my findings. Seems like just the right dpIDs need finding.

1CH version:

Mine is this:

you could sniff out the additional dpID(s)
https://www.elektroda.com/rtvforum/topic3970199.html
https://www.elektroda.com/rtvforum/topic4038151.html

https://github.com/openshwprojects/OpenBK7231T_App?tab=readme-ov-file#features

or post your full factory firmware dump (or send it to me to reset if you joined it to wifi/Tuya) or extract the config data if you've already converted to OBK without backup

I already flashed it.
Here is the full 2MB dump of Tuya FW. I had it connected to WiFi if it matters.

Anyways it seems that things are very similar, because when using your autoexec.bat:
*both physical switches work (on both CH's/lamps)
*CH1 dimming and switching works from webui

Just have to find the dpIDs for CH2 for basic functionality to work.

edit:
Looks like CH2 continues from dpID7, very logical. I'll write up the new autoexec.
