Starting with Smart Shades firmware version 2.2.0 / Smart Shades app version 2.2.0 there is a new feature called Slippage Compensation. If your shade has a (nylon) cord without beads then the cord might slip while the motor is moving causing both the lowest and the highest positions to get lowered with each movement. The slippage can take place both on the top where the cord is attached to the shade mechanism and on the bottom where the cord is attached to the Smart Shades gear wheel. With Slippage Compensation you can specify the amount the cord slips so that the Smart Shades can automatically compensate the slippage by moving less or more accordingly.
Measuring the slippage
Follow these steps to measure the slippage
- Select Change Lowest and Highest Position from the Smart Shades app device settings screen
- Move the shades to their lowest position
- Use a pen to make a small dot on the cord (a good place to make the dot is somewhere in the mid position of the shades). Make another dot on the same height / same place on the wall (you can use a tape on the wall for easier cleaning afterwards).
- Move the shades to their highest position
- Go back to the Smart Shades app main screen
- Move the shades to Fully Closed position using the slider
- The shade has moved one full cycle so far: from the bottom to top (during setup) and back to the bottom
- Now you can measure the slippage per one full cycle which is the distance between the dot on the wall and the dot on the cord
- We suggest to make more than one cycle (e.g. 3-5 cycles) to have more average slippage measurement
- Move the shade to the top and back to the bottom using the slider on the Smart Shades app main screen
- Count how many cycles you move in total
- Measure the total slippage which is the distance between the dot on the wall and the dot on the cord
- Divide the total slippage by the total cycles count to get the average slippage per one cycle
- Use the average slippage per one cycle in the app
- The device will compensate all the movements made so far and all the future movements using the slippage measurement entered while the shade is moved
