Tuya ATORCH AT4P(WP/BW) Smartlife Energy monitor (BK7231N) (C3BS) (CH573F) (BL0924)
Hi All,
I have started on getting OpenBK ready for this device ,
https://pt.aliexpress.com/item/1005004407477380.html?gatewayAdapt=glo2bra
It is a 100A wifi (disabled BT) energy monitor.
Internals pictures as follows
i total of 3 units each Identical on the outside, purchased as the same model and 2 of the 3 software wise have less features but higher software version.
Software AT4PWP V1.04 will show Power Factor, Voltage, history, current (A) ,load (W) , energy used kw/h , frequency, bill and cpu temp on client app and main screen.
Software AT 4PBW V1.05 will show Voltage, Load (W) and current with on/off history on client app but displayss all the above and humidity ? on the lcd. it also has exact same pcb and markings.

Very good job, did you figure dpIds yourself? From what I can see, there was no compound device-specific packet types? For example, this device: Hiking DDS238-2 Smart Meter had one custom packet... [Read more]
The dplds were pulled from the logs once i figured that the baud rate had to be changed (many a time i fotgot to add that and assume wiring at fault, lmao) most stick to the listed ones for power/current/voltage/frequency... [Read more]
I found more, this one passed my eyes but brain did not see, when i unpacked/decrypted the factory firmware i found a .json file with ID's in it that match this hardware { "gw_bi":... [Read more]
So on the next device (type AT4PBW, Mcu ver 1.05) i am not getting any feedback at all, in the logs there are quite a few issues Info:TuyaMCU:TUYAMCU received: 55 AA 03 00 00 01 01 04... [Read more]
Having a full communication dump from the original firmware can help a lot in such cases. It is easier to investigate when you know what's supposed to happen. Info:TuyaMCU:TUYAMCU received:... [Read more]
Attached is a realterm hex dump of the device with factory firmware. I reset the device the recorded the provisioning from both the TX and RX of the signal , attached is capture(TX of tuyamcu) and capture2... [Read more]
Any more information on those captures? Current voltage, power, etc? Lots of data here https://obrazki.elektroda.pl/5760334200_1671363689_thumb.jpg Some of packets looks like custom data: ... [Read more]
Ok, I finally got openbk to build for the N device i have , lots of face palm moments my side getting build env up, I like to use platformio for my ide on win/linux and normally not a issue but as I also... [Read more]
You don't need to do the capture via UART, you could launch OpenBeken and then do test with 60W bulb and 10W bulb and show me what OpenBeken receives, I think. [Read more]
I have flash the lastest bin file but it seems the device wont go past the ez-pair screen (not accepting the ok from bk device? ) if i do the command tuyaMcu_sendQueryState i will get this in the logs... [Read more]
So i did some more digging and found this https://developer.tuya.com/en/docs/iot/tuya-cloud-universal-serial-port-access-protocol And they mentioned the Commands in use, I noticed a few on there not... [Read more]
0x21 also seems to be specific to this device. I am not sure about the structure of 0x21 packet yet. Sample whole packet: 55AA002100400108772E74656D702E300004000000160C772E68756D69646974792E3000040000004608772E706D32352E3000040000002607772E6171692E3000040000006C30 71... [Read more]
The packet 0x21 is response to the command 55 aa 03 34 00 01 03 3a , proactively request weather data , and the breakdown of 0x21 is as follows this is found on the link i posted before ... [Read more]
I will try to add parsing of that data to OpenBeken later today. Will commit soon: https://obrazki.elektroda.pl/1114962300_1671636492_thumb.jpg [Read more]
I have been able now to read voltage/current from the device and then manually calculate power , here is my patch , drv_tuyaMCU.c else if (sectorLen == 4) { iVal = data[ofs +... [Read more]
This is not the correct way to do that. Please see this commit: https://github.com/openshwprojects/OpenBK7231T_App/commit/5a03649f7261413fba0d2c0794894c347381a5a8 https://obrazki.elektroda.pl/7852314300_1671699832_thumb.jpg... [Read more]
@ElektrodaBot I have a wifi problem before it works well but after the last power outage the wifi does not work and the green light no longer lights up I tried all the parameters like setting to zero and... [Read more]
It definitely sounds like the power outage may have caused some damage to your WiFi equipment. Let's try to troubleshoot the issue step by step. 1. Power Cycle : Although you've mentioned setting things... [Read more]
