Ideas for shade up and down reporting?

[simonmason]

I have a number of RF shades that I managed to get my Bond hub to control.  Unfortunately the commands get through about 9 out of 10 times.  I was thinking that it would be great to have some sort of sensor that reported whether the shade was up or down.  I was thinking about a small magnetic switch sensor that could be hidden in the bottom of the shade that triggers when it gets to the bottom.  Does anyone have any ideas?  Thanks

Or a microswitch if it's heavy enough and you can align it properly.

Many motor/servo systems detect current drawn that increases radically when the motor locks rotor at the end of travel. Think power windows in a vehicle.
