setDateTime gives error in home assistant addon

[gw1urf]

After encountering the bug mentioned in issue 318 (inverter seemed to set month number to 13 overnight!) I thought I'd add a home assistant automation to set the date and time nightly, by publishing e.g.:

giv-tcp/control/********/setDateTime = "31/12/2024 11:54:00"

Unfortunately, this fails because write.py's setDateTime function tries to do:

logger.info("Setting inverter time to: "+iDateTime)

where iDateTime is a datetime object. This results in an error about concatenating a string and a datetime object.
The fix would seem to be using str(iDateTime) or similar.

I've been unable to test a fix, though, because I just don't understand docker and Home Assistant well enough. There are so many overlay filesystems lying around and I can't find the base copy of write.py to edit such that the edit survives the addon restart.
