Hello all! I am about to close a simplisafe-python PR that will add support for SimpliSafe locks; once it’s in place, I’ll begin working on a PR to add this functionality to HASS. 
Although I am the codeowner for SimpliSafe, I don’t happen to own one of these locks. I’m reaching out to you all to compile a list of people able/willing to help me test this component prior to its release in HASS proper.
Leave me a comment if you’re interested. Thanks!
