Wemo Light Switch fails to function in HomeKit Automations activated by "Accessory control" triggers

[danielraffel]

What issue do you have? Please be as thorough and explicit as possible.

Following a recent update to version 6.1.2 of the Wemo plugin, my Wemo Light Switch stopped working with HomeKit Automations set to trigger on "Accessory control". The switch functions normally in all other aspects, except as a trigger in this specific scenario.

Previously, my setup allowed the activation of my kitchen light to also turn on the dining room light, and vice versa. This system had been functioning well for years until I updated the Wemo plugin. Apparently, I had skipped several updates.

In an attempt to resolve the issue, I reverted to installing older versions of the Wemo plugin, restarting and testing the HomeKit automations each time. It was only when I downgraded to version 6.0.4 of the Wemo plugin that the automations resumed working correctly.
