Hi!
I’m trying to convert my ZMAI-90 to ESPHome or Tasmota (ESPHome, if possible).
I’m using this tutorial and template as base: ZMAi-90 Digital Energy Meter (ZMAi-90) Template for Tasmota (blakadder.com) and Creation Factory: Reverse engineering the ZMAi-90 DIN rail meter/switch and integrating with Hass.io using Tasmota - Part 2
After opening my device, I figured that mine came with WB3S module, which is not compatible with Tasmota/ESPHome…so I have changed it to ESP-12E (same size and pinout) and I got this working, almost. I can upload ESPHome and Tasmota firmwares, both works fine.
In Tasmota, I could not get any function to work. Button, relay, power information (current, voltage, power), nothing…just the firmware that loads. But I could enable TuyaMCU and got some debug information from that (more below).
In ESPHome, I also got ESP to communicate with TuyaMCU and got some DP’s:

But the only DP that I have successfull made work was 16 and 1. DP 16 is the main device relay and DP 1 is the cummulative power consumption stored in TuyaMCU device. None of the othe items is working.
This is the code that I’m testing with ESPHome:

Like I said before, Tasmot could not read anything is this device…not even relay. I’m using these commands to configure tasmota (copyied from URL in this msg):
Backlog SetOption66 1; TuyaMCU 0,17; TuyaMCU 32,18; TuyaMCU 31,19; TuyaMCU 33,20; SetOption59 1
From Tasmota, I got a lot more debug information…but I don’t have any idea how to use/configure these information. Note that even after copy/paste command from URL, I got an invalid function id from tasmota:
19:12:09.732 CMD: Backlog SetOption66 1; TuyaMCU 0,17; TuyaMCU 32,18; TuyaMCU 31,19; TuyaMCU 33,20; SetOption59 1
19:12:09.793 RSL: RESULT = {"SetOption66":"ON"}
19:12:09.001 TYA: TuyaMcu Invalid function id=0
And this is the full log. During this log, I was reading these values in device LCD:
Voltage: more or less 128.3
Current: 0.96A
Power: 0.12 (probabily 120W, since I was using 120W bulb to test)

I guess it will be at start of June
but you could try to find correlation between zmai’s displayed values and data from log.
