can you add new device its from xexun model XT01 and other one is from eelink model TK419 can you add it in your system
You mean add support? Are they not supported?
yes, its not supported
Then this is not the right place for asking. You can either post a request on GitHub. Make sure to provide documentation and your testing results proving it doesn't work. Or you can contact support if you need it now and happy to sponsor the implementation.
ooh i think you are the one you have to add it, i will contact them.
