Elgato Eve HomeKit Services & Characteristics

A work in progress collection of proprietary and as of yet undocumented HomeKit characteristics and their UUIDs used by Elgato Eve.

Based on the work by gomfunkel and 0ff. Characteristics and data dump for Door, Motion and Thermo thanks to @NebzHB.

More infos not yet incorporated in the comment section.

This list is not including all Eve accessories available and some services and characteristics still make no sense to me. If you have anything to contribute, please leave a comment. There is no guarantee that the information listed below is correct.

My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add this to your Sidekiq configuration:

if ENV["PROFILE"]
