If an OLED Reset pin has been selected using the PIN configuration, it makes sense to also send a reset signal to this pin before initialization of the display. The current value 0 doesn't send this signal, not even when a reset pin has been selected. Hence the change of value 0 into reset_pin >= 0. If no reset pin was set, the value of this variable is -1.
With calibrated shutters and ShutterPosition<x> 100 the resulting position may not be 100. This is due to 2 issues. a) percentage is calculated wrong from position due to numerical precision. b) real_position and subsequently position after movement is slightly smaller than max_position.
a) is fixed here by avoiding calculation when position is equal to calibration point
b) open, not fixed here. Issue further depends on start_position which makes it hard to reproduce. Maybe 'stop_position_delta=20' results is real_position not reaching max_position.
When ShutterCalibration<x> is called without any arguments no response was given before that allows to read out setting like for other commands. Workaround was to call ShutterRelay<x> <y>.
New command "ShutterButton<x> <a> <b> <c> <d> <e> <f> <g> <h> <i> <j>" added that allows to assign a tasmota button <x> to control shutter <a>.
Single press button shutter is set to position <b>. Double press button shutter is set to position <c>. Tripple press button shutter is set to position <d>. Hold button shutter is set to position <e>. Disabling any button action is given by <b> ... <e> equal to "-". Any press of the button while the shutter is moving will immediately stop that shutter.
Global steering of all your shutters at home is supported by MQTT. By any button action an MQTT command can be initiated to the <grouptopic> of the device. For single press button this can be enabled by <f> equal to "1". Disabling is indicated by <f> equal to "0". Double to hold actions are given by <g> ... <i>, correspondingly. When <j> is equal to "0" only "cmnd/<grouptopic>/Shutterposition<y> ..." with <y>=<x> is fired. When <j> is equal to "1" <y>=1...4 is used to control any shutter number of a tasmota device having same <grouptopic>.
Easy setup for an "up" button:
ShutterButton<x> <a> up (same as ShutterButton<x> <a> 100 50 74 100 0 0 0 1 1)
Single press will move shutter up to 100%, double press to 50% and tripple press to 74%. Holding the button for more than the hold time (SetOption32) moves all shutters with same <grouptopic> up to 100%.
Easy setup for an "down" button:
ShutterButton<x> <a> down (same as ShutterButton<x> <a> 0 50 24 0 0 0 0 1 1)
Single press will move shutter down to 0%, double press to 50% and tripple press to 24%. Holding the button for more than the hold time (SetOption32) moves all shutters with same <grouptopic> down to 0%.
Easy setup for an "updown" button:
ShutterButton<x> <a> updown (same as ShutterButton<x> <a> 100 0 50 - 0 0 0 0 0)
Single press will move shutter up to 100%, double press down to 0% and tripple press to 50%. No hold action and no other shutter control by MQTT.
