@nicnicol The stub means you need to add an openhasp section to the configuration.yaml file with an objects entry below each plate name. Like so:
openhasp:
plate_my_room_1:
objects:
# ...
plate_my_room_2:
objects:
# ...
plate_my_room_3:
objects:
# ...
I don’t think this thread is the best place to troubleshoot the configuration of the custom component. Please join our Discord channel or use the openHASP thread.
