SSL certificate verify failed

I used a subset of the small example script that you provided in the README.md. But when executing (env variables are set properly), I get the following error:

Traceback (most recent call last):
  File "bin/test.py", line 19, in <module>
    manager.start()

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)

Any ideas?

My script:

#!/usr/bin/env python3.6

from meross_iot.manager import MerossManager
from meross_iot.meross_event import MerossEventType
from meross_iot.cloud.devices.light_bulbs import GenericBulb
from meross_iot.cloud.devices.power_plugs import GenericPlug
from meross_iot.cloud.devices.door_openers import GenericGarageDoorOpener
import time
import os

EMAIL = os.environ.get('MEROSS_EMAIL') or "YOUR_MEROSS_CLOUD_EMAIL"
PASSWORD = os.environ.get('MEROSS_PASSWORD') or "YOUR_MEROSS_CLOUD_PASSWORD"

if __name__=='__main__':
    # Initiates the Meross Cloud Manager. This is in charge of handling the communication with the remote endpoint
    manager = MerossManager(meross_email=EMAIL, meross_password=PASSWORD)

    # Starts the manager
    manager.start()

    # You can retrieve the device you are looking for in various ways:
    # By kind
    bulbs = manager.get_devices_by_kind(GenericBulb)
    plugs = manager.get_devices_by_kind(GenericPlug)
    door_openers = manager.get_devices_by_kind(GenericGarageDoorOpener)
    all_devices = manager.get_supported_devices()

    # Print some basic specs about the discovered devices
    print("All the bulbs I found:")
    for b in bulbs:
        print(b)

    print("All the plugs I found:")
    for p in plugs:
        print(p)

    print("All the garage openers I found:")
    for g in door_openers:
        print(g)

    print("All the supported devices I found:")
    for d in all_devices:
        print(d)

    # At this point, we are all done playing with the library, so we gracefully disconnect and clean resources.
    print("We are done playing. Cleaning resources...")
    manager.stop()

    print("Bye bye!")

I have also bumped into this problem, and have found out that it was because for python 3.6 or 3.7 on OSX requires a post install of certificates. The solution is from here https://stackoverflow.com/questions/27835619/urllib-and-ssl-certificate-verify-failed-error For 3.6 run this command in terminal /Applications/Python\ 3.6/Install\ Certificates.command

I’m running on Python 3.9 and encountered the same issue. The command can be modified to: /Applications/Python\ 3.9/Install\ Certificates.command And this resolves the issue.
