I wrote this component a while ago and having trouble migrating it to the new layout in 0.93.
I created the directory layout to match the example_load_platform one and added a manifest.json file. The directory looks like this:
custom_components/
processor/
__init__.py
mqtt_code.py
manifest.json
manifest.json
{
"domain": "processor",
"name": "Processor",
"documentation": "https://www.example.com",
"dependencies": ["mqtt"],
"codeowners": [],
"requirements": []
}
You can find the source code for the files above in the Github repository.
I read the release 0.93 notes and release 0.92 notes which mention the following:
- Load requirements and dependencies from manifests - Developers - Setup entity platform will set up its component now despite DEPENDENCIES. (@rohankapoorcom - #22717)
I thought adding the manifest file as I did above would fix the problem
I am not getting any useful error in the logs (even when setting the logger component to debug.
All it says is that the mqtt_code integration cannot be found.
Are there any breaking changes with homeassistant.loader’s get_component method? That throws an error as well.
I didn’t think the migration would require a change in source code, other than moving and renaming files around.
The configuration looks like this:
processor:
- platform: mqtt_code
topic: /rf/all
callback_script: script.buzz_short
event: True
entities:
- name: Black Button
type: panel
mappings:
button:
payload: 1870753
actions:
default:
- service: fan.toggle
entity_id: fan.bedroom_fan
The last known working version is 0.91.3 (before the big migration in 0.92 of course).
Edit:
I upgraded one version at a time and resolved all warnings in the logs before moving to next version. I am now at a point where the migration problems are resolved. However, there seems to be an undocumented breaking change to homeassistant.loader

Any idea why this would stop working in 0.93?
