IQ Switch® PowerSense® Series 2 Intelligent Switch Connection The 2-gang prototype intelligent switch is wired as shown below. Both LIVE and NEUTRAL connections are required at the intelligent switch. The load is connected between the L1 or L2 and N terminals. Figure 1: Hardware Connection Diagram 3 Network and MQTT Setup 3.1 Initial Startup Each intelligent switch is pre-loaded with software and set up to function out of the box.

IQ Switch® PowerSense® Series Figure 2: Holding down the two buttons (>10s) - The unit will enter a configuration mode and the touch buttons will remain green in color. The Vekin logo will also start to breath/flash. The unit will now activate a mobile hotspot/ Wi-Fi network. Please note that the switch will still be fully functional in the configuration mode. Figure 3: Device in configuration mode 2.

The IP address and Gateway will be obtained automatically. o All MQTT information is required. o Enter 0 in the SSID and Broker areas for standalone usage. (No Wi-Fi connectivity). o Choose dimming technique (SMART dimming is recommended). o Press send after all the areas are filled in. o The browser will respond with the following message.

IQ Switch® PowerSense® Series RestoreDefaults – Load default values into memory as listed in Table 3. LED’s will cycle through their colors. 4.3.2 Power Consumption Reporting The intelligent switch is capable of automatically report power consumption changes via the MQTT network. The feature can be enabled and adjusted by selecting POW in the MQTT topic.
PAGE 15
IQ Switch® PowerSense® Series BlockTime – Adjust the block time after movement is detected. This parameter blocks any movement triggers for the duration set. If this parameter is set to 2 seconds, the movement detection will be ignored for 2 seconds after a new movement trigger. Timeout – Adjust the timeout period after movement is triggered. Any movement triggers will reset the counter which is compared with the Timeout parameter. Invert – Enable or disable the invert movement detection action.

IQ Switch® PowerSense® Series method. Before executing manual calibration, it is important that the unit is properly installed and that the room is made as dark as possible. During manual calibration, the intelligent switch will automatically switch on all selected gangs to 100% to measure the maximum light that the connected load can supply. The value is then stored in memory and the selected lights are switched off to finish manual calibration. AutoCalibrate – Turns on the auto calibration feature.

IQ Switch® PowerSense® Series Topic: VINT/IDxxxxxxxxxxxx/CHg (g = 1, 2 or 3) Message: GroupSelect – Each gang or channel can be grouped to a local group which is specific to the selected intelligent switch. If gang 1 and 3 is grouped in one intelligent switch locally, a command to the VINT/IDxxxxxxxxxxxx/GROUP topic will adjust the dim level of gang 1 and 3 together. Any combination of local grouping can be selected.
