The Switchmate integration and Bluetooth integration interference problem

[jluo98]

The problem

The Switchmate integration is unable to connect to switches on startup if the Bluetooth integration is enabled.

The issue can be resolved by doing the following steps:

• Disable the Bluetooth integration
• Attempt re-connection to the Switchmate switch (e.g. Calling the homeassistant.update_entity service)
• The switch becomes available
• Re-enable the Bluetooth integration if needed by other components, which does not cause further issue

Hey there @Danielhiversen, @qiz-li, mind taking a look at this issue as it has been labeled with an integration (switchmate) you are listed as a code owner for? Thanks!

Thanks @jluo98. Can confirm this is an issue. Unfortunately, it looks like there is a conflict between the scanning of the Bluetooth integration and Switchmate? Tagging @bdraco here, who might be able to help us further.
