Incorrect Child Node warning of devices and eventual crash within Homekit.

[wolfiegrr]

Describe The Bug: Too many devices are reported per Child Node even though it is well under 150 per node, eventually after ~2-4 weeks, the entire system becomes unresponsive, Bridge needs to be removed and re-added to homekit.

To Reproduce:

• Have an environment with over 300 Accessories combined (dimmers, switches, shades).
• Create 3 Child Bridges, and enable Switches to Child Bridge 1, Dimmers to Child Bridge 2, and Shades to Child Bridge 3. This ensures that no single child bridge has over 150 devices.
• Pair all three child bridges with Homekit.
• Warning of"[12/8/2023, 6:46:17 AM] [Crestron Home Platform] Returning more than 149 devices, Homebridge may crash - 329" is reported in the error log for each child bridge.
• Difficult to reproduce, but after about 3-4 weeks of running flawlessly, despite the warning, child node connected devices begin to report "Unresponsive" in homekit. Ie., first Shades, then a week later Switches.
• Accessories within Homebridge itself continue to report proper status and show online, its Homekit that begins to report Unresponsive.
• Requires complete removal of each bridge from HomeKit, and pairing again.

Expected behavior:

• because no individual Child Node has over 150 devices, it should not report this warning per child node.
• Homekit connected bridges should not report Unresponsive per child-node accessories.

You can safely ignore the warning. Please try using version 1.1.6, there is a fix addressing stability issues.

Just updated to 1.1.6 the same day of that post. I'll monitor it on the new version. Thank you!

Fix in 1.1.6 didn't help. The issue the same as mentioned in the issue #3 As a workaround, you don't need to remove the bridge, deleting cached accessories will help. In my case (running Homebridge on Raspbian):

Ssh to the Raspberry Pi cd /var/lib/homebridge/accessories/ sudo hb-service stop sudo rm cachedAccessories.[YOUR-BRIDGE] sudo hb-service start

The Homekit should work properly after this.

I believe @mcm246 fixed the issue in 1.1.8 along with incorrect warning Please try it.
