Flashed Tuya Smart Meter 80A CBU Chip: No Metrics Showing in WebUI After Setup

Hi,

I have flashed my Tuya smart meter with CBU chip. I have access to the Web UI and I was able to connect to my Wi‑Fi without any issue.


But after some research on YouTube and this forum, I'm not able to configure the device to receive the metrics.

I already tried another topic at https://www.elektroda.com/rtvforum/topic4053493.html, but I didn't solve my problem.

I was able to fetch the DIP list from the Tuya Developer Console. It's attached in the post.

I also attached a list of commands generated by ChatGPT, but the values are always zero. I'm not sure if I need to configure anything extra on pin config.

I hope someone can give me some help here.

Thank you

there's also this thread here for such a device https://www.elektroda.com/rtvforum/topic3946128.html

pop back into the Tuya dev site and grab the Query Things Data Model json too

I have added these commands to autoexec.bat, but I can't receive any byte data from Tuya in logs.

ExtraDebug:TuyaMCU:TuyaMCU heartbeat_valid = 0, product_information_valid=0, self_processing_mode = 1, wifi_state_valid = 0, wifi_state_timer=0

startDriver TuyaMCU
tuyaMcu_setBaudRate 9600
tuyaMcu_defWiFiState 4

any signs of life if you toggle flag 26



have you determined which UART is connected to the TuyaMCU? from which are debug logs output?



If you have a flash backup I can check it's talking TuyaMCU and on which UART. If there's a chance it contains your wifi creds from pairing before backup feel free to DM it to me and I'll give it a go/reset it.

Anyway, won't it be dual BL0942?

got any pics of the insides?

Hey @divadiow, sorry for the delay, but I was out of the home.

This is dual, but I only use one.
