How to get all parameters from a 2 channel power meter

Configuration

1

I have a 2 channel wifi power meter Amazon item /dp/B0D7CV1S1H )
In the SmartLife app, it shows the readings from the 2 channels separately - and their sum as well.
When I used the Home Assistant Tuya integration, and added the meter - it seems to ONLY be showing the sum values.
I really need BOTH channel values separately.
Looking at the diagnostics json file, Home Assistant seems to be showing the values of the 3 “entities”.
There are 5 “functions”, and 3 “status” items that look relevant.
The 3 “status” items seem to correspond to 3 of the “functions”. (these appear to be the actual values, the “functions” appear to be descriptions of the values, range, unit, etc… - but not the actual values)
Those 3 would probably be enough.
There are 2 other values that are displayed in smartlife, that are NOT included in the json file - but would be useful.

After lots of searching, I found this thread, that appears to have solved the problem:

The msg from bushwoelie on Apr 2024 (several black images) has lots of useful information - which I have no idea where it came from.
Then a few msgs later, he shows some partial changes to configuration.yaml to get those values into HomeAssistant.

It’s still VERY unclear to me what changes need to be made to get all the data items.
Would someone please help me figure this out?

I had the same issue of buying these expecting both channels I was going to use the first channel to detect if my car was charging and do some beacon lights to tell me if it wasn’t plugged in by the end of the night But Not having Really any support for this device crippled that severely. I get maybe two updates a day and even then I don’t trust them. tuya It will even show you active voltage power and power factor on both channels With an update rate of every 10 seconds. There’s a whole lot more data being sent over to tuya Then Home Assistant.

I have also been trying to get into Local tuya But have had little success From every guide I have found.
