HomeKit Device Integration - "KeyError: 'characteristics'"

[ammacdonald3]

The problem

I recently added two new Aqara door sensors and one new Aqara motion sensor. The sensors initially fed over to Home Assistant and automatically created entities through the HomeKit Device integration. However, very frequently, the entities report a "Became Unavailable" status. My resolution is to reload the HomeKit Device integration, which seems to temporarily resolve the issue before it happens again.

The sensors integrate with the Aqara app and report statuses there without issue. Additionally, I have dozens of other Aqara sensors that have been integrated with Home Assistant through the HomeKit Device integration (via an Aqara G2H camera hub). All other sensors have generally performed without issue, but since adding these three new ones, they periodically report "Became Unavailable" as well (but not as often as the three new sensors).

Restarting Home Assistant and/or reloading the integration provides a temporary fix until it eventually starts happening again. Restarting the hub (Aqara G2H camera) didn't do anything.

This error meads the device it out of resources:

outOfResource: -70407,

[ammacdonald3]

Thank you for the help! Do you know what the "out of resource" error means? Is it possible that too many devices are connected to my Aqara hub?

[bdraco]

The vendor decides when to throw that error. You would have to ask them

[ammacdonald3]

Sounds good, thank you again! I'll close out this issue and explore alternate methods (maybe connecting these sensors directly to HA with Skyconnect).
