I am currently playing around with a change in home assistant core, specifically the template helpers, aka homeassistant/helpers/template.py
On my dev setup, it seems to work. Before creating a PR, I'd like to be able to try out it on one of my real home assistant instance. As this is not part of a component, just uploading it to custom_components won't work, right? Is there another way? I am running Home Assistant OS.
PS: Is this the right place to ask this question? The docs still refer to #devs_core 🙈
