@Stuart-Martin Maybe an old topic but still of interest to some Currently trying to do the same, did all those steps too (came up with some, found others) but struggling when doing pip3 install cryptography which is part of the pip3 install homeassistant process. Did you have any issues with libffi by any chance? The idea is to have a micro-valid zwave secondary controller. Cheap and very small. Thanks, Ka.

@Lucas-Godoy , you may could change the title to "memory full" instaed of bricked and mark it as resolved (inkl. add tag resolved).

@Samuel-Mathieson i have thought of using a home asssitant as a sort of security device that would sense movement/sound and as response trigger a tear gas or pepper spray along with playing a pre-recorded message from any of several locations based on the location of the intruder. the HA playing the part of a presumed occupant would be able to react dynamically to the movements of the intruder. plus, it would notify me and i could join in remotely and interact with the intruder in some pre-defined way. otherwise a HA play no part in my daily life. i've never been interested in having a recording device in my home 24/7 to talk to and ask questions, etc. but, i'd be interested in reading what you have come up with.
