What about just adding a subheading to the readme?

@deviantintegral Could we add more details, like the fw version?

@KTibow To keep things organized, we will put all the "gotchas" in this file. We can talk about how to handle exceptions like "AuthorizationError", "AuthenticationError", "StorageError" etc. The user must read this file before opening an issue.

I'm sorry, I didn't capture the firmware version prior to upgrading.

What is the devtype and current fw version?

import broadlink as blk
d = blk.hello('192.168.0.16')  # Example IP address
d.auth()
print(hex(d.devtype))
print(d.get_fwversion())
