Home assistant depricated some older methods in 2025.5. this was well documented and had a long warning period... you should refer to the LocalTuya Repo - https://github.com/rospogrigio/localtuya/
LocalTuya have not yet implemented the fixes
There has been various issues raised on their repo
rospogrigio/localtuya#1851 rospogrigio/localtuya#1864 rospogrigio/localtuya#1871 rospogrigio/localtuya#1905 rospogrigio/localtuya#1932 rospogrigio/localtuya#1940 rospogrigio/localtuya#1949 rospogrigio/localtuya#1977 rospogrigio/localtuya#1980
and finally the release broke it: rospogrigio/localtuya#1982
NB: there is some discussion of work around in this most recent issue which implement the charge from unmerged PR's
there was been a PR on the repo for a while but it has not been approved rospogrigio/localtuya#1968
There is also a different PR rospogrigio/localtuya#1983 that implents an alternate fix.
This is not directly a Home Assistant Issue, LocalTuya is a non-supported Custom Integration so it is entirily on owners timeline.
Please keep in mind that not every integration developer has a lot of time to work on their integration projects. so whilst you should direct questions to their repo, Please be polite and respectful of their time.
This should be a fairly small task for them to merge and release a fix as multiple people are already using the fix so it has been tested.
Then it is likely someone will fork the repo however before that happens it is likely some time will pass.
