It defines the maximum time it takes to detect a change. You might be lucky and check just after a change.
For control it should be immediate as the command is sent straight away. So if you just use Homey then everything will be in sync.
If you use the phone app or a remote to control the device then it could take Homey a while to catch up and show the correct state.
Connecting directly won’t effect the polling but you end up with two devices in Homey for each physical device.
The BLE fixes should improve the reliability and speed. The BLE polling is fixed at 30 seconds as the only limits are with Homey. But again, this is for reading the status. Sending commands is done straight away but it takes time to connect and send so that could be anything from a few milliseconds to a few minutes.
I use these as Homey doesn’t have the range to reach my devices. The app doesn’t need to poll these as they send changes to Homey immediately and are very fast. Controlling devices still takes a few seconds as that is the nature of Bluetooth.
I hope that hasn’t been too confusing.
