Strange values for HMS-700-2T inverters #21

Closed tannercollin closed 3 months ago

tannercollin commented 3 months ago

I'm getting strange values for HMS-700-2T inverters. For example: 2496 voltage, 6000 frequency, and active power being way higher than what the array is spec'd for. Nominal array power is 410 W + 23 = 9430 W.

Not sure what's happening, I suspect the protobuf fields don't align? I tried poking around in RealDataNew.proto, but couldn't make any sense of it. Do you have any pointers? Thanks!

Here's my get-real-data response:

These data actually look fine. You need to divide by e.g. 100 to get the real value.

Have a look at:

https://github.com/suaveolent/ha-hoymiles-wifi/blob/main/custom_components/hoymiles_wifi/sensor.py

There you can see the right conversion for each value.

You're right, thank you!
