ID 18 has values 122, 247, 123, 244 - idk what's that
ID 19 is from 0 to 612, isn't it power divided by 10? The bad thing is that you turned off power and I am not sure... but most likely it's power
ID 20 from 0 to 2503... voltage? Again, not sure why is there a 0?
Here is a decoded dump:

Well, ID 19 oscillates around 600, ID 20 between 2457 and 2501. It might confirm it's voltage and power.
ID 18 is 247, what may that be?
Maybe I am wrong and one of them is a current?
Yup...
Let's assume resistive load.
60/250= 0.24smth
So it's voltage, current and power. Just which one is which.

Ok, now what is that?

It sets fnID 52 to 16000, then 24000, then 50000, then 24000 again.. I can't see anything else happening here.

Do we need a relay control as well?
So far, we have found a current, a voltage and power channels.

I also need a test with a 120W load or 30W load because... I am not sure which one is current and which one is voltage.
Or maybe we can guess by precision?

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:

TurkeyMan · Answer

Yes, I bought a 60W incandescent light bulb for testing these with a resistive load

I think the voltage was high today, ~250V, high sun, lots of solar. I guess the small number was current?
I don't know why the SmartLife app reported current as 0.1A, because it's a resistive load, and as you show, 60/250 = 0.24.
So, 18 is mA, 19 is W*10, 20 is V*10? Seems plausible, except those early readings of ~120mA aren't right...

What's odd here is that it doesn't seem to report cumulative Wh... which means you can't measure energy... slow poll rates will miss high frequency fluctuation, and the total energy will accumulate error.
Maybe it's reporting energy since the last poll? Maybe that's why 18 is jumping 122, 247, 123, 244? Maybe the report rate is not perfectly regular?
Hmmm, okay, so 60Wh/hr == ~0.016Wh/second. Those messages are reported a few seconds apart... maybe there's a scaling factor that makes that make sense...? Maybe you sum them for total energy consumption?

There's no relay in this device. It's just a meter... and as a dedicated meter, I'm really surprised it doesn't accumulate kWh internally for accurate energy reporting!

On the TX line; "mostly nothing" except that `08` packet... any idea? Doesn't look important, but you don't seem to have a record of that packet type in your software...
I have no idea what fnId 52 is supposed to be for! How will we configure items of configuration, to expose values that will be transmit to the mcu?
For instance, I feel like a quality configuration for this device will create an integer value called "Maximum power", given some bounds like 0-80000, and then transmit the value to Tuya if the user changes it. Can we do that now?

p.kaczmarek2 · Answer

We need a bit more samples to figure out everything. It's something for initialization, but we have logs saved so I don't worry about it now: Command Word Description0x00 Heartbeat detection.0x01 Query product information.0x02 Query the working mode of the Wi-Fi module.0x03 Report the network connection status of the device.0x04 Reset the Wi-Fi module and switch the network configuration mode.0x05 Reset the Wi-Fi module and select a network configuration mode.0x06 Deliver DP commands.0x07 Report DP status.0x08 Query the device initialization status.0x0a (Optional) Start OTA upgrade.0x0b (Optional) Transmit the OTA upgrade package.0x1c (Optional) Obtain the local time.0x0e Test the Wi-Fi function (product testing command) You can map any OpenBeken to any TuyaMCU dpID. You can then set this channel with setChannel 15 80000 command and driver will automatically forward the value to TuyaMCU. OpenBeken doesn't need to know the exact channel meaning, it's flexible, it just forwards data. It's designed to be scriptable. More samples and we will figure it out. No idea about cumulative Wh yet. But... we could just calculate it on Obk?

TurkeyMan · Answer

If we can only poll immediate state, then accumulating wH is not accurate. High frequency fluctuation between polls will hide cumulative error.
It's probably okay for some applications, but it would be good to advertise clearly that it's an estimate somehow...
By contrast, I think the chips that report wH accumulate internally with a very good precision and report "wH since last poll" or something?

p.kaczmarek2 · Answer

Then maybe we can bet on: More data samples would tell us if that's what we think it may be.

romulus73 · Answer

The meter is really poor measurement 0d 0.2A, no standard of accuracy Up to 80A, Meters only on shunts, don't you feel sorry for the money?
For this money, it's better after Modbus without a combination with any Atroch shunt
Fasten the clamps and check the accuracy at 5A, this is the standard meter calibration load

mfmoro · Answer

Hi, I was able to flash the firmware. Could you please tell me which configuration I have to apply? Kind regards

mfmoro · Answer

I tried to run both tuyamcu driver and the BL0942 driver but I get no reads. I also tried to use get channel 18, 19, 20 but I get only 0.

p.kaczmarek2 · Answer

You should not use BL0942 driver at all. The procedure is to run TuyaMCU driver, and then check Web App log for packets with their dpIDs, and then map dpIDs to channels in the config.

Do you get any TuyaMCU logs in Web App log when you run only TuyaMCU driver, but not the BL0942?

p.kaczmarek2 · Answer

Okay, it seems you're an OBK beginner. So, you should start with the following autoexec:


startDriver TuyaMCU
tuyaMcu_setBaudRate 115200
tuyaMcu_defWiFiState 4

The baud rate setting was taken from one of the posts above. If you read the topic carefully, you will see a report about baud rate 115200 used there.

The default WiFi state makes device think (TuyaMCU device) it is always paired.

Okay, please try this autoexec and give log again, so we can check if you are receiving something

As you can see, you are receiving the data now. Now you need to figure out the correct interpretation for dpIDs.

I have already done some research on that above, as I said:

Quote:

ID 20 from 0 to 2503... voltage? Again, not sure why is there a 0?

So now you should see our docs:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/README.md
and see channel types.

And update your autoexec:


startDriver TuyaMCU
tuyaMcu_setBaudRate 115200
tuyaMcu_defWiFiState 4


setChannelType 2 Voltage_div10
setChannelType 3 Power_div10


// linkTuyaMCUOutputToChannel dpId variableType tgChannel
//ch 2(dpid 20) voltage
linkTuyaMCUOutputToChannel  20 1 2
//ch 3(dpid 19) power watts
linkTuyaMCUOutputToChannel 19 1 3

Now save this, and reboot, and you should get voltage and power reading, assuming that the dpIDs are correct. Can you check?

There is much more to read, but we need to guess dpIDs.

mfmoro · Answer

Hi ,
thanks, I added also dpId 18 to ch 4:


startDriver TuyaMCU
tuyaMcu_setBaudRate 115200
tuyaMcu_defWiFiState 4

setChannelType 2 Voltage_div10
setChannelType 3 Power_div10
setChannelType 4 Current_div1000

// linkTuyaMCUOutputToChannel dpId variableType tgChannel
//ch 2(dpid 20) voltage
linkTuyaMCUOutputToChannel  20 1 2
//ch 3(dpid 19) power watts
linkTuyaMCUOutputToChannel 19 1 3
//ch 4(dpid 18) current in mA
linkTuyaMCUOutputToChannel 18 1 4

Now we need to decode futher dpIDs. There should be also a total consumption somewhere. Maybe frequency as well?

mfmoro · Answer

Yup. Is there a way to send the full serial output to MQTT so I can dump it easily for a long time?

elektradi · Answer

I got myself one of these too. 1. Need to cut any PCB tracks to flash it? 2. Does it help look at tasmota's code for BL0942? Thank you.

p.kaczmarek2 · Answer

Nope, but we can try to add something like that. Currently Web App log is a way to go. Most likely yes. We have very good BL0942 driver, but it is not used here. BL0942 is not connected to WiFi module. It connects to TuyaMCU. This is TuyaMCU device, and we have TuyaMCU support, so everything comes down to decoding dpIDs so we can receive data and display it on GUI and forward to MQTT.

elektradi · Answer

I'm confused. There are:1. MCU2. BL09423. Wifi module? What is this? Isn't the wifi module part of MCU?@mfmoro can share how you flashed? Desolder?

mfmoro · Answer

Yes I desoldered the pad between the main board and the vertical pass-through board and soldered the rx, tx, gnd and 3V3 to a serial board to program it.
You don't need to detach the board only desolder it.

p.kaczmarek2 · Answer

@elektradi TuyaMCU devices have two separate brain, one is WiFi module, second is an extra MCU:

elektradi · Answer

I see. Thank you for the clarification!I just to make this work first, are the TuyaMCU and wifi module both on that tiny detachable CB3S module?If I replace CB3S with an ESP8266, does it the ESP8266 talk directly to the BL0942?

p.kaczmarek2 · Answer

TuyaMCU is the STC chip here:

There is no need to remove anything, but if you really don't want to use TuyaMCU protocol, you can remove the MCU and wire BL0942 directly to CB3S and use OpenBeken.

OpenBeken can emulate Tasmota features very well, most of the commands and JSON format are compatible, Tasmota device groups are also compatible, so you get ioBroker, etc compatibility out of the box.

elektradi · Answer

Hmm, tough call haha. Thank you for the work on openbk!

Which pins do I have to wire to CB3S to BL0942? And what would be the configuration?

To be honest, I decided to buy this device right after reading about openbk. I thought it was fully supported already. Haha.

So, I have never flashed openbk before, first timer. If you can guide me through the hardware wiring, I'm more than happy to help with decoding the protocol.

p.kaczmarek2 · Answer

Wait, wait a moment, @elektradi . I may be missing something here, but why don't you want to try just using this device directly with OpenBeken TuyaMCU driver? I don't know if I should ask, but I am not sure what's the motivation behind using BL0942 directly. There is no need to do that? From what I can tell, we already have most of DPids for this device working: There are still some dpIDs not figured out, but current, watts, and voltage are already here.... so most of the work is done.
