Linking Xiaomi smart switch to Deconz

[EGO01]

Thanks for the update

@Robban

For event id naming change it is this comment in HASS 0.85 release notes

Slugify changed, which can impact entity ID creation if the entities had names with either a - or characters outside of A-Z and the integration has no unique IDs. We now better handle the characters and substitute it with an alternative instead of removing that character.

I did read that breaking change but I didn’t automatically think it would apply to deconz event only entity ID. Also I have no other buttons so had assumed the ID would be unique

Clearly me not understanding exactly how it all works together. Anyway I got there in the end, but it wasn’t my first port of call when I was trying to problem solve. I think it didnt help as I had been focussed on the port issue to begin with.
