@topsworld I think you should also contact the PM or Hongyu to fix the broken spec to solve the original problem.

@topsworld Should incomplete events be passed to the application? Will this cause problems?

If spec doesn't provide the definition of a piid, from intergration's perspective, it's something either redundant or unnecessary. Maybe it's a private argument used by Mijia App, and should be ignored by HA.

Done.
