The relay switch for the first channel: active high, power-on default low level. Note: As a switch button, there will be a period of high level at the moment of power-on, which requires a pull-down (1~4.7K) resistor to ground.

The device obtains information in different ways in the two modes, read below section for details. 4.3 The Wi-Fi module basic workflow The flashing mode of the Wi-Fi status light on the device represents the its current network working status. The specific status includes the following seven types: This is the Forum CUL-40039 Culina Konect Wireless On/Off Kinetic Switch Non-Dimmable Wi-Fi Module - a wifi and RF wireless receiver.This item works with Alexa and Google Assistant, and the manufacturer has their own app to control this system. The upper and lower layers of the PCB where the module is placed should not be routed as much as possible. Do the copper-clad processing, and the PCB from the module antenna to the nearest pin of the module should be hollowed out as much as possible. The module PCB antenna area and the 15 mm extension area need to be clear (copper, trace on the board, and component placement are strictly prohibited), refer to the following figure: The switch for the second channel, active low. APP configuration pin, when the low level> 5S, enter the pairing mode.

External reset signal: active at low level, externally need to pull up a 10K resistor to 3.3V, and connect a 100nF capacitor to ground. Count downtimer: The count down is to facilitate the user to perform one-time timing operations, such as turn on/off the device after 30 minutes. It is very convenient to turn off a device after running a period of time. This device supports up to 24 hours of count down. The flashing of the Wi-Fi status light is in a cycle of 2 seconds, as shown in the figure, the low-level light is on and the high-level light is off. Detailed explanation of each status: Strong signal up to 40m range outdoors, 15m indoors for plasterboard, 8m indoors for concrete or glass

Environmentally friendly

Power-on status configuration: The power-on switch status can be configured on or off through the APP, and the default power-on status is off. The 40039 is a single channel Wi-Fi relay switch receiver. Part of the Culina Konect system from Forum Lighting. This a completely wireless switching system converts the kinetic energy produced by physically switching the switch into electrical energy to control your lights via remote switch and receiver. PSF-B04 supports timer. The eWeLink APP provides four timing modes to facilitate the use in more scenarios.

The relay switch for the fourth channel, active low. APP configuration pin, when the low level> 5S, enter the pairing mode. Note: The chip configuration pin needs to pull down (1~4.7K) resistor to ground.PSF-B04 module can be used as a 4-channel switch, which can control the switch locally or remotely through APP. This item is suitable for use with single, double and triple kinetic switches plus a single switch key fob. WiFi and RF Wireless Receiver Non-Dimmable in Matt White - Specs The Gateway acts as a conduit for any RF Quinetic products to be linked together thus creating a hybrid system for both RF and WiFi connectivity. The compact design means it can be installed almost anywhere. It has a range of up to 40m from the switch when outside, or 8m away when indoors and can be controlled not only by the switches.
