 It is meant to provide some playground.

 # Home Assistant Add-on: OctoPrint Proxy

 Small _haproxy_ based reverse proxy to have OctoPrint accessible from Home Assistant with a memory consumption less than 10Mbyte.
 
 Works okayish with OctoPi based installations, others not tested. Feedback welcome.
