Looks like modifying requirements in custom_components/currentcost/manifest.json from:
"pyserial-asyncio==0.4",
to
"pyserial-asyncio==0.6",

Solves the issue

Same problem: the stated solution seems to have got things back in order (after a couple of restarts, as usual!).

Thanks for the tip.

[DanielDomB]

Yes thanks for the tip, that solved it

[masxmedia]

Was also having same problem and changing 'pyserial-asyncio==0.6' fixed it. Thank you!

This fix worked for me too thanks. Seems I needed a reboot after change was made.

I tried the fix aswell, but HA won´t let me restart:
[140359694122896] The system cannot restart because the configuration is not valid: Platform error sensor.currentcost - Exception importing custom_components.currentcost.sensor

How did you manage to restart?

Edit: Forcing a restart from Proxmox did the job.

Thanks heaps for this - I have no idea how you find out these answers but I am on the latest and working again.

Thanks @marc252. Your fix works great. I'm not sure why the commits by @HarvsG have not been merged and released. This caused me hours of headaches today trying to get this to work before I came across your post!

Maybe this project has been abandoned?

Thanks for the tip, worked for me too.
