Domoticz Bluetooth Presence Detection

Update script being used as presence detection. Previously would take arguments for -s and -b (switch and bluetooth) and only check 1 device. Required multiple cron entries, 1 for each device. This could lead to polling issues if more devices are added. This new script “Should” only poll once for all devices. There’s a pause when it’s searching for the first device but consecutive devices fly through so I think it’s working.

Had to us – as separator. : in mac address would be confusing, tried ; but conflicts with bash, was going to use a space but would need to account for that in the argument parser and – was just easier.
