I'd suggest reading up on the driver by reading the first post and the last 100 or so in this thread to begin with:
I know it's a lot, but this really isn't something you should attempt without being well informed. There's also the official Tasmota docs:
@RobertLask has the same device as you and may be able to help, he has had some issues that may be hardware related however.
You will probably need to use my unreleased Closed Beta driver, once you've read up on this more, please tell me and I can add you.
