Dependancy pb: ModuleNotFoundError: No module named 'meross_iot'

Hi Alberto,,

I'm a total beginner in python and home assistant, so my question is maybe stupid. I have followed your explanations to install Meross cloud iot in Home assistant via HACS but i have this error message.

Error loading custom_components.meross_cloud. Make sure all dependencies are installed
Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/loader.py", line 338, in _load_file

File "/config/custom_components/meross_cloud/init.py", line 11, in

ModuleNotFoundError: No module named 'meross_iot'

What have i done wrong ?

Thanks

Alberto, it looks like a Hass.io/HACS might have changed something. I'm getting the same error and it appears as though it's not finding your meross_iot library. It's not mentioned in the install instructions, but do we need to pip install your library before running the add on?

I'm not even able to do a pip install meross_iot at the moment. I get the following error:

ERROR: Could not find a version that satisfies the requirement meross-iot (from versions: none) ERROR: No matching distribution found for meross-iot

So I figured out what was happening. hass.io is running docker to run any plugins, unlike a more "traditional" Home Assistant install sitting on top of a regular Linux install. The meross_cloud HACS package is expecting to be able to pull from pip3 to get the meross_iot package, which works fine under vanilla ubuntu:
sudo apt-get install python3-pip; pip3 install meross_iot

We can actually take HACS out of the equation completely with a hassio add-on. I threw together a sample repository and ALMOST have it working. But it's late so I'll have to track down why python3 in the Alpine Linux docker image can't seem to find the init.py script.

Anyways, from hassio go to "Hass.io" -> "ADD-ON STORE" -> Add new repository by URL (https://github.com/guitarmanusa/meross_cloud) -> Add then refresh the page. The new repository should show up there. Add your meross email and password from the config page.

Sorry for the late update but after copying meross_iot library in config/custom_components and rebooting HA, everything work.
Perhaps, it would work too without manually copying the library and just rebooting.
Thanks a lot for your work
