Hi,

Thank you for the feedback!

That means, that for some reason HA didn't install PyPlumIO package during startup.

Try doing the following:

• Remove the integration
• Restart HA
• Reinstall the integration
• Restart HA again

This should force HA to install integration dependencies.

Now I can't add integration:
Config flow could not be loaded: {"message":"Invalid handler specified"}

[denpamusic]

Couple more questions then. Are you using hacs? Did you restart HA after reinstalling integration and waited for a couple minutes afterwards. Did anything related to integration appear in the log?

Hello @denpamusic , I have a similar issue.
After updating HA to 2025 version I updated this integration to 0.4.10, but it couldn't be loaded and from logs it was indicating missing requirement - pyplumio. So I followed your advice here (remove, restart, add, restart) and now, when I am adding the integration under Settings->Devices & Services-> Integrations->Add Integration->Plum ecoMAX It briefly says

Please wait, starting configuration wizard for Plum ecoMAX

but after couple seconds it ends with

Error: Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble

In logs I can see:

Unable to install package pyplumio==0.5.30: error: Failed to fetch: https://files.pythonhosted.org/packages/61/04/810c30f8c95c27e2e350704885f32b92ab03b4b9dfc51cc7040b839526ed/PyPlumIO-0.5.30-py3-none-any.whl.metadata Caused by: Could not connect, are you offline?

• I haven't changed anything on my DNS setup.
• I am able to wget the url from HA terminal without any issue

[danielkovarik2]

Update - manage to fix the issue by adding google dns to ha network settings

After removing and install again, now it working.

There was some major PyPI outage on January, 4th, reported on https://status.python.org/, so original issue is probably related to that.

There was no downtime reported today though, so it's kind of weird.
Still it's not really the issue with integration, but if possible I'll need to find and document a better way to retry dependence installation other then reinstalling the whole integration.
