Correct values in HA for pulse-energy-meter-be6-30397, but wrong ones with nibe/modbus tcp

[danielcb]

Hi,
I'm trying to get values for my pulse energy meter (BE 6) (Nibe SMO S40). I've set it up in Homeassistant and everything works correctly (shows around 9.600 kWh).

If I try it manually (either via a modbus cli client or via this project) I get the value "3132358670".

I also (correctly) get an out of range error, since the allowed max value is lower that the value I get:

  "30397": {
    "title": "Pulse energy meter (BE6)",
    "factor": 100,
    "unit": "kWh",
    "size": "u32",
    "min": 0.0,
    "max": 2147483647.0,
    "default": 0.0,
    "name": "pulse-energy-meter-be6-30397"
  },

The code I used is basically the default example with:

heatpump = HeatPump(Model.SMOS40)
coil = heatpump.get_coil_by_name("pulse-energy-meter-be6-30397")

The error I get is

AssertionError: Raw value 3138912270 is out of range for coil pulse-energy-meter-be6-30397

Do you use any other 32bit parameters? I think you need to toggle word_swap for your setup.
