Hey all,
i am working on an integration which polls high frequently a device API to get the current sensor values and populate them to HA.
I plan to implement Significant Change Support as documented here
After execution of python3 -m script.scaffold significant_change two files has been created
//platform-folder/significant_change.py
//test-paltform-folder/test_significant_change.py
As mentioned in the docs in significant_change.py it should be checked if changes are significant and depending on the boolean response the entity should get updated (or not)
However even if I put a simple “Return False” in the signifcant_change.py the values gets updated all the time. I also put there a breakpoint in the debugger and saw this code never get called.
Do you have an idea what’s needed to get this signifcant_change_function be called? Please find below the current content of the significant_change.py
"""Helper to test significant Binary Sensor state changes."""
