TOMZN TOMPD-63-LW Wifi Multi Function (DIN) WB3S (BK7231T)
Hello, I recently bought this DIN power meter, it looks good, does anyone have this model with OpenBK working correctly?
I have searched a lot in the forum and I have not found anything related to this model, so I open a thread.
The brand of the device is TOMZN and the model is TOMPD-63LW 63A, apparently it is similar to TOMZN TOML-VA 63A.
I'm new to this and need some initial help.
Specs:
The product can cut off L and N both.
Rated voltage: 230V; Frequency: 50Hz/60HZ
1. Remote control ON/OFF at anytime from anywhere by phone.
2. Review current, voltage, leakage current, total kWh on phone.
3. Timer function in smartlife TUYA app.
4. Can set over voltage/under voltage/over current/leakage current in app or can set these by manual.
5. Under voltage protection 140V-210V (adjustable) (default: 170V).
6. Over voltage protection 225V-295V (adjustable) (default: 265).
7. Over current protection 1A-63A (adjustable) (default: 40A).
8. Reconnect time (delay on time): 1s-500s (default: 30s).
9. Voltage/current/kW calibration: -9.9%-9.9%.
10. Action time: 1-30s (default 1s).
11. Power consumption less than 2W.
12. White backlight.
Here are all the images he was able to collect.

I guess it's a TuyaMCU device, so it will work without any problem. Do you know how to do UART data capture in a safe manner? This device is mains powered, so doing capture may be dangerous. We could... [Read more]
@crash1912 Can you take a better picture, maybe of the bottom board? And if possible, maybe include the markings from the LCD controller? [Read more]
Thanks for answering, I'm new to this, I have a moment of mental garbage with a lot of information, openbk, tasmota, esphome... but I'm advancing little by little. I don't know how to do UART data capture... [Read more]
What is under capacitor here: https://obrazki.elektroda.pl/3855322500_1692046358_thumb.jpg This is WB3S bot: https://obrazki.elektroda.pl/9001953900_1692046409_thumb.jpg (Bottom view, not... [Read more]
@crash1912 There is a similar post you can read - https://www.elektroda.com/rtvforum/viewtopic.php?p=20686225#20686225 Also, you can check this post on how to do UART capture safely - https://www.elektroda.com/rtvforum/viewtopic.php?p=20667319#20667319 And... [Read more]
You may be right. I can see UART traces there. They go through resistors. https://obrazki.elektroda.pl/6372361200_1692049934_thumb.jpg That would mean that one would have to desolder them to temporary... [Read more]
With a multimeter, I can't find continuity between TX1, RX1, and any other board connection pin, only VDD and GND. I think I'll need to solder wires on TX1 and RX1... Under the capacitor, I can see: HC89F0541... [Read more]
Well, no surprises here, considering that it clearly looks like TX1 and RX1 go through resistors to MCU: https://obrazki.elektroda.pl/7348413800_1692098093_thumb.jpg It's TuyaMCU. https://obrazki.elektroda.pl/6677601000_1692098172_thumb.jpg... [Read more]
You are right, without a bridge between pin 22 and GND, you cannot read/write anything. Using a little mini hook, I can create a bridge without soldering. For TX/RX, I held male pins to the board using... [Read more]
2MB flash can contain your SSID if you paired it. Please post if you can, if not, please post only Tuya JSON. See how to extract JSON: This will tell us which baud rate is your device using. [Read more]
The device is new, never used, does not contain any personal data configured for me. If it contains anything, it is from the factory (any device key or anything, I don't know). I have attached a backup... [Read more]
That's good enough. Well done. So baud rate is the default, slow-speed one. Okay, so let's start with this autoexec.bat: // start TuyaMCU driver startDriver TuyaMCU // always force 0x04 WiFi state... [Read more]
Ok now driver is already loaded: https://obrazki.elektroda.pl/6551659400_1692293974_thumb.jpg Yes, i can toggle relay from physical button. In the recording tab, the data is very abundant, these... [Read more]
There isn't much in the logs, but they seem to suggest that dpID 16 is a boolean, it may be a relay. So, now autoexec.bat should look like: // start TuyaMCU driver startDriver TuyaMCU // always... [Read more]
Correct, DP16 is a power switch relay! and using configuration from EAMPDW-TY63 now can see more data! but some is wrong... OverVoltage, UnderVoltage, Current and Leakage values appears 0, but OverVoltage... [Read more]
How does your current web app log looks like? Which dpIDs are working? You've jumped quickly to very advanced config and I am not sure if it's entirely correct. Have you tried to use tuyaMcu_sendQueryState... [Read more]
Ok, well I think so too, I've gone too fast :) tuyaMcu_sendQueryState force refresh arbitrary? this looks good!! I like this!! Works great!! ¿Can refresh each 5~10s automatically? ok, now let's... [Read more]
Repeating event can be used to do some action periodically: // NOTE: addRepeatingEvent [RepeatTime] [RepeatCount] // code below will forever toggle relay every 15 seconds addRepeatingEvent... [Read more]
Repeating event is wonderful, i added "addRepeatingEvent 10 -1 tuyaMcu_sendQueryState" and works amazing. Possible stupid question: if channels are like variable and dpID's are same as constant... [Read more]
