+## Shutter with Stepper Motors
+Stepper motors can be used to operate shutters and blinds. The configuration is very similar to the  Circuit Safe (Shuttermode 1) configuration. To operate a stepper motor requires driver module such as the A4988 and uses EN (enable), DIR (direction), STP (Stepper) for controls. If everything is defined correctly the shuttermode 3 will be reported at boot time.
+
+Tasmota supports a maximum of four shutters with one stepper motor per shutter simultanously. In very rare conditions where two or more shutters simoultanously move the last mm it can happen than one shutter moves to far.   
+

+- Modifying a 28BYJ-48 12V stepper motor from unipolar to bipolar [tutorial](https://coeleveld.com/wp-content/uploads/2016/10/Modifying-a-28BYJ-48-step-motor-from-unipolar-to-bipolar.pdf)  
+- [Bill of Materials](#Bill-of-materials)  
+
+### Example configuration  
+`EN` and `DIR` are on `Relay1i` and `Relay2` respectively. Please be aware to use the **inverse** relay for the enable signal.  
+
+The `STP` signal is assigned as a `PWM<x>` component where `<x>` matches the number of the shutter (e.g., `PWM1` for `Shutter1`). The shutter feature adjusts the PWM frequency to operate the motor for proper shutter operation. The stepper motor frequency setting is a global setting all PWM components on the device. This means that all shutters on the device will operate at the same speed. Therefore no PWM devices other than shutters can be connected to the same Tasmota device.  
+
+The frequency of the PWM can be changed from 1000Hz to any value up to 10,000Hz. The command `ShutterFrequency` globally changes this. Be aware that most 12V operated motors cannot work faster than 2,000Hz. 5,000Hz.10,000Hz is possible by increasing the supplied voltage to 24V and use `ShutterMotorDelay` to allow a slow speed up/speed down. The maximum voltage of the A4988 is 36V. The TMC2208 is much more silent than the others but also significant slower and does not like high frequencies. For example, the speed at 24V is half o A4988
+
+Finally a GPIO **must** be assigned as `Counter1`. This counter is used to keep track of the steps and send the stepper to the correct position. The `Counter1` GPIO must be connected to the `PWM1` GPIO. Otherwise the stepper and your shutter will run continually or freeze up randomly.
+
+Only **bipolar** stepper motors may be used (see above).  
+
+You must properly configure the stepper motor driver (see above).
+
+`ShutterOpenDuration` and `ShutterCloseDuration` can be different. Shutter with Stepper motors always match positions exact. There is no need to vary `ShutterOpenDuration` and `ShutterCloseDuration`. Anyhow, if you decrease `ShutterCloseDuration` the Shutter will close with a higher speed on a virtual higher `ShutterFrequency` if possible. Same vice versa.
+
+You can define a soft start/stop by defining a `ShutterMotorDelay`. This causes the driver to ramp the speed up and down during the defined duration. The change of the `ShutterMotorDelay` does NOT change the distance the shutter makes. This is very convinent to trim the accelerate and decelerate rate without changeing the distance.
