Invalid handler specified when loading integration

[karlinurswick]

I have had the wiser integration working fine in HomeAssistant working within a VirtualBox machine on my normal use laptop for some time and have now moved to a dedicated machine for home assistant. the new machine is a similar setup, runs windows 10 with HomeAssistant operating in VirtualBox Linux machines as before. I have installed HACS and then subsequently downloaded The Wiser package. When trying t add this via the "Add Integration" Button I get an error - Config flow could not be loaded: {"Invalid handler specified"} and the integration will not load.

When checking the logs, I see this; Logger: homeassistant.config_entries Source: config_entries.py:3249 First occurred: 7:19:29 AM (3 occurrences) Last logged: 7:33:21 AM Error occurred loading flow for integration wiser: No module named 'aioWiserHeatAPI'

I have searched via google for a couple of evenings and cant find any way to resolve this, can anybody offer any advice? Thanks.

What version of HA are you running and by what method? HAOS, docker etc?

I am running version 13.2, core 2024.11.3, supervisor 2024.11.4 and believe this is a supervised installation in a Linux virtual (virtualbox) machine. Followed the instructions from here - https://www.home-assistant.io/installation/windows/

OK. If it is not loading the aioWiserHeatAPI library, there will be an error in the logs saying why not. Can we find what that is.

Not sure how much of this is needed so have added all the log from where the wiser issue starts, thanks for taking the time to look at this. 2024-12-03 17:04:05.492 ERROR (MainThread) [homeassistant.config_entries] Error occurred loading flow for integration wiser: No module named 'aioWiserHeatAPI'
