Fix for double lock events and more

• Removed status checking and fixed double lock events (thanks @formatBCE !)
• Introduced sensor for lockEvents
• Fixed reload service (thanks @TheDescender !)
  Enjoy!

Introducing "reload" service

Introducing reload service, that allows to reload the integration without needing to reboot HA.

Introduced diagnostics and handling of wrong status

Introducing the possibility, available since HA 2022.02, to download the diagnostics.
It is possible to download:

• integration diagnostics, which contains token and config entry
• device diagnostics, which contains the device info and the logs of the last 5 minutes (even if they were not enabled)

Also, if a wrong lockStatus msg is received (i.e., different from AAxxxxxx0204xxxx....), the integration entered an unrecoverable state: this release should fix this issue.

New low_batter binary sensor and filtering for double actions

Introduced 2 main improvements:

• creation of a binary_sensor for low_battery status
• filtering to prevent to launch another action when an operation is already in progress

Improvements in custom firmware handling

• Introduced parsing of lockStatus field (i.e. FFF3 characteristic)
• Introduced auto retries in custom_device.py
• Telemetry messages are now taken into account for availability
• Fixed non-lock devices filtering

Introduced support for ESP32 custom firmware

Introduced support for ESP32 custom firmware by @formatBCE. On configuration it is possible to select which firmware is installed between Tasmota and the Custom firmware.

v1.1.0: introduced auto-retry and fixed battery status

• Introduced auto-retry (number of retries is configurable in the Integration options)
• Fixed battery percentage, by properly converting battery voltage

Fixed wrong FAILED status

Introduced MAC address filtering and improved status check in order to filter out wrong FAILED status.

Fixed state bouncing at the end of lock/unlock operation

Fixed state bouncing at the end of lock/unlock operation (back to previous status, and then to new status).

Status handling improved

Improved status handling for devices whose status changes also with manual operation.
