Yes, you will. I don’t know if anyone has determined what the .bin file does for this update. I have updated all mine to 1.41 (.otz file only) for the issue you have described.
I personally have been tempted to update to 1.45 which adds the ability to set the LED color to white. However, with that FW update, the .bin file would be required. I’ll probably do that as soon as work calms down a bit.
Nope! Nothing to change. You’ll just see the LED reflect any switch changes, briefly, and then the Notification goes right back to what it was.
