Okay, adding this here ... scratching my head on it ... sort of working

Listed below is the __init__.py file. I added in the async_remove_config_entry_device and logging to debug. This code is to delete a device. Either an existing device that is present, or a missing device removed from the user's installation.

What I cannot figure out is the result Device / service not found. When doing the action, the device deletes sucessfully in the device registery, but responds with the error.
I beleive the code that calls the async_remove_config_entry_device is the HA's device_registry.py , line 134 ... I cannot figure out that the error message gets popped. I am wodering if there is a callback that I am missing.

You can simulate the removing of a sensor by ...

• Going into the Kidde app, select the location anme, then click on a device's Show Device Settings and renaming it and hitting the back arrow.
• Then go into HA and reload the main integration by selecting the three dots and selecting reload.
• The sensor will now be a new device in HA, and you can delete the old device.
• What i do is then go back and rename it back to the original name, reload in HA, then delete the missing device.
• You can turn on debugging to see more details.

Here are the three dialog boxes that are presented when you delete.
