HA 0.96 - No module named 'robovac'

[JXGA]

Hey,

I have a new issue after updating to 0.96;

Error while setting up platform eufyrobovac Traceback (most recent call last): File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 126, in _async_setup_platform SLOW_SETUP_MAX_WAIT) File "/usr/local/lib/python3.7/asyncio/tasks.py", line 442, in wait_for return fut.result() File "/config/custom_components/eufyrobovac/vacuum.py", line 42, in async_setup_platform from robovac import Robovac, get_local_code ModuleNotFoundError: No module named 'robovac'

It was working fine before the update. I think there's a new Vacuum template in 0.96, so maybe that's interfering? https://www.home-assistant.io/components/vacuum.template/

Thanks, I'll take a look at the changes in 0.96 and see if that's the problem. My own Home Assistant instance recently stopped working after upgrading so once I get it working again I'll investigate.

Just gotten HA up and running again, I'll upgrade to 0.96 and see what the damage is.

Replicated on my local instance.

As a workaround, manually installing the Python module with pip3 install robovac will get you going again. Still looking into why Home Assistant has stopped doing this automatically. This issue doesn't seem to be present in 0.95.4, so downgrading may also help you.

This did the trick...

edit: remove email footer rubbish

[BnMcG]

Good to hear. I'm still comparing what's changed between 0.95.4 and 0.96.0 to work out why HA stopped auto-installing the package, will update here when I figure it out.

[BnMcG]

I've identified the issue with the help of some of the folks on the Home Assistant Discord server - I'll push out the fix tomorrow morning.

Thanks for your time on this...

Picked up another error, but I don't think it relates to this one...; Failed to call service vacuum/return_to_base. [Errno 106] Socket is connected

So the status of the vac is detected and correct on HA first startup, then it does not update status (until HA restart) and I can not control the vac from HA.

[Errno 106] Socket is connected

That error looks super similar to #3 - I think I've previously worked around it by restarting HA and the Robovac, and my best guess at the moment is it's something to do with the update code not letting go of something it's supposed to.

Once I've pushed the fix that allows the component to properly install on 0.96 I'm going to dig into why sometimes the transport endpoint remains connected / why HA tries to open a new connection when one already exists. It seems intermittent and I know on my local installation I can go for days/weeks without this error popping up.

Thanks for your patience!

I've tagged v0.1.1 that contains the fix for the dependencies not being correctly downloaded. The issue was the domain listed in the custom component's manifest.json wasn't correct ("robovac" instead of "eufyrobovac").

You should be able to drop-in the new files, restart Home Assistant and be good to go. You probably won't see any actual changes on your instance as you manually installed the dependency earlier, but from this point onwards if a new version is released with updated dependencies they will be downloaded automatically.

I'll take a look at the transport issue today.
