Overview Shelly Plus 2 PM roller shutter

With its two relays the Shelly Plus 2 PM controls a roller shutter or blind drive and measures power and energy. This function block is used when the device is operated as a roller shutter in the device menu. The block offers operation via operating mode and position as well as the operation via long-time and short-time commands known from KNX. For positioning to work, the drive has to be calibrated once.

Inputs
BA Operating mode Travel command as a numeric value: 0 = stop, 1 = open, 2 = close. The command is sent on every change of value.
PO Position Target position in percent using the Shelly notation: 0 = closed, 100 = open.
LZ KNX long time Long-time command in KNX style: 0 moves up, 1 moves down. The drive travels to the end position or until the next command.
KZ KNX short time Short-time command in KNX style for adjusting the slats. If the drive is moving it is stopped. If it is standing still it moves briefly: 0 up, 1 down.
KP KNX position Target position in percent using the KNX notation: 0 = open, 100 = closed. The value is converted when it is sent to the device.
KA Calibration On every change of value the device starts its self-calibration. The drive moves fully up and fully down once and thereby learns the travel time.

Outputs
S1 Switch 1 status State of the push-button for up connected to the device.
S2 Switch 2 status State of the push-button for down connected to the device.
R1 Relay 1 status State of the relay for the travel direction up.
R2 Relay 2 status State of the relay for the travel direction down.
BS Operating mode status Feedback of the operating mode set last.
PS Shelly position status Present position using the Shelly notation: 0 = closed, 100 = open.
PK KNX position status Present position using the KNX notation: 0 = open, 100 = closed. For display in a KNX visualisation.
PW Power Present active power in watts.
PW Energy Energy meter reading of the drive in watt hours.
AI Addon analogue input Voltage at the analogue input of the addon. Only present when the addon is enabled.
DI Addon digital input State of the digital input of the addon. Only present when the addon is enabled.
T1 Addon temperature 1 Temperature of the first DS18B20 sensor, or of the DHT22 if that one is selected. Only present when the addon is enabled.
T2 Addon temperature 2 Temperature of the second DS18B20 sensor. Only with the setting "+Addon DS18B20".
T3 Addon temperature 3 Temperature of the third DS18B20 sensor. Only with the setting "+Addon DS18B20".
F1 Addon humidity in % Relative humidity of the DHT22 sensor. Only with the setting "+Addon DHT22"; the output then takes the place of T2.

Parameters

MQTT topic Topic of the device, exactly as in the MQTT settings of the device. Example: shellyplus2pm-AABBCCDDEEFF

Short time duration Travel time in milliseconds the drive moves on a KNX short-time command. This sets the step size of the slat adjustment. The controller works in a 100 ms grid, the value is rounded up to full 100 ms. The default is 500 ms.

Addon Evaluation of the optional Shelly addon. None hides the additional outputs. +Addon DS18B20 shows three temperature outputs, +Addon DHT22 one temperature and one humidity output.
In addition to the outputs listed, the command generate addresses creates an address named timeout. It is set to 1 when the device has not sent a message for a longer period of time.
