Changing "linked_battery_sensor" for Ring Z-wave contact sensor in HomeKit Integration

Configuration
1

Hi all,

I’ve seen a few folks mention that the Ring contact/door sensors show in HomeKit with 0% battery life even though HA shows it coorectly. I’ve reviewed the diagnostic file for the HomeKit bridge exposing the contact sensors and I know the problem is that the “linked_battery_sensor” attribute is set to expose the temperature - which is 0 because these sensors do not include temp. The thing is that I cannot figure out where to change this “linked_battery_sensor” without doing a completely customer HomeKit entry in the configuration.yaml file. Can someone point me in the right direction to change the “linked_battery_sensor” attribute of an entity within a particular HomeKit bridge?

TIA.

Here is the diagnostic.json snippet from the bridge that shows the incorrect sensor being used for linked_battery_sensor attribute.

For those of you that may stumble upon this facing the same issue with these z-wave sensors - here is the easy fix:
Go to each ring contact sensor device and disable all of the settings “Diagnostic” settings that are not applicable. For me, I disabled the following:
Battery is Disconnected
Battery temperature is low
Charging Status
Fluid is low
Low Battery Level
Maximum capacity
Overheating
Recharge or replace
Rechargeable
Temperature
Used as backup

Once I did all that and reloaded the bridge, HomeKit picked the battery level diagnostic as the “linked_battery_sensor” and all was find in my Home app.

FYI: I’m using the z-wave.js controller in home kit and a Zooz 800 controller USB stick.

I hope this helps anyone else having this issue.
