Unable to successfully configure Leviton Decora Wi-Fi integration

[securitypedant]

The problem

I have the following Leviton devices:

3 x DW15P Plugin Outlet
1 x DW6HD Dimmer switch
3 x D215P Plug in Outlet
1 x D215R Wire in Outlet

Home Assistant by default finds a few of them. I see three plugs and one outlet showing in my discovered devices list, all 4 of them are marked as HomeKit devices. Note I don’t use HomeKit at all in my house.

But I want to be able to integrate all of the Leviton devices. So I looked at the options in Add Integration and saw Leviton Decora WiFi. https://www.home-assistant.io/integrations/decora_wifi

I added the section to my configuration.yaml, restarted Home Assistant. But nothing happens. I’ve doubled checked the email and password I am using, it’s correct. There is nothing at all in the system logs, looking at the Python code for this integration and it seems it should at least be logging something if it cannot connect.

What version of Home Assistant Core has the issue?

core-2023.9.1

What was the last working version of Home Assistant Core?

I wrote my own Python test file based on the source here, I was able to authenticate and also enumerate the devices. So the issue seems to be something to do with Home Assistant not loading this integration.

import logging

from decora_wifi import DecoraWiFiSession
from decora_wifi.models.person import Person
from decora_wifi.models.residence import Residence
from decora_wifi.models.residential_account import ResidentialAccount

email    = "house@mydomain.com"
password = "3uthisisntrealRwH"

logger = logging.getLogger(__name__)

def connect(email, password):
    session = DecoraWiFiSession()

try:
    success = session.login(email, password)

    # If login failed, notify user.
    if success is None:
        msg = "Failed to log into myLeviton Services. Check credentials."
        logger.error(msg)
        return

    # Gather all the available devices...
    perms = session.user.get_residential_permissions()
    all_switches = []
    for permission in perms:
        if permission.residentialAccountId is not None:
            acct = ResidentialAccount(session, permission.residentialAccountId)
            for residence in acct.get_residences():
                for switch in residence.get_iot_switches():
                    all_switches.append(switch)
        elif permission.residenceId is not None:
            residence = Residence(session, permission.residenceId)
            for switch in residence.get_iot_switches():
                all_switches.append(switch)
    print(all_switches)

    # add_entities(DecoraWifiLight(sw) for sw in all_switches)
except ValueError:
    logger.error("Failed to communicate with myLeviton Service")

connect(email, password)

I ended up forking the repo and running my own development environment, it worked in there. So I went back to my own server, checked the configured and restarted the server (which I had already done before) and now for some reason I can see the Decora WiFi entities! So its working...
