HLW8032 power sensor implementation request

[turbatus]

Describe the problem you have/What new integration you would like

I installed esphome on my Gosund P1 power strip (8266/8265 controller) and the power meter is not working, showing always 0.0 values. After some research I discovered that it has a different power sensor than the usual model. Instead of a CSE7766 it has HLW8032 (still uses the serial communication, though). I would like to request to add HLW8032 to esphome, if possible. Please describe your use case for this integration and alternatives you've tried:

As mentioned before, the HLW8032 power metering sensor is not yet implemented in esphome. This is the sensor used by the newer Gosund P1 power strips. All the returned values are 0 (using CSE7766 component). Additional context

I already tried with Tasmota, same behavior, as it uses the CSE7766 configuration. Example Github repo on HLW8032: https://github.com/Khaalidi/HLW8032 If you can guide me on how to extract relevant info I would be more than happy to do it. Thank you for your support and effort! Cheers!

did you try https://esphome.io/components/sensor/hlw8012.html ?

Yes, I have tried that, did not work. Returns 0.0 value all the time.

I second this request, the new model for the Athom smart plugs Tasmota EU Plug V2 also comes with the HLW8032 power sensor. It comes pre-flashed with Tasmota.

Tasmota seems to have support for the HLW8032 since 2019.

According to Athom’s support, this device is working using the cse7766 as shown in this example:

I have a Deta GPO that has this chip. The chip only require RX. Ensure correct RX pin in config. This code works for me. I have WB2S chipset.
