@WGentine mentioned that problem earlier so I included it in the email I sent my Neo contact.
A firmware update that fixes the energy reporting won’t help since ST doesn’t support firmware updates so I’ll make the handler ignore weird values. Hopefully they’ll be able to send me the new manual so I can fix the configuration parameters.
Unfortunately since it’s the EU model having problems I won’t be able to test the changes myself so I’ll most likely PM it to you and the others so you can test it for me.
