Check whether the LED reacts when the WTS-1x sensor is switched on and whether a value is sent to ConnectedCooking.
Ensure that a WGT-11 gateway within range is connected to ConnectedCooking.
If the signal strength is weak, switch the WTS-1x off and on again to adjust the calibration to the current distance to the WGT-11.
(Switching off: briefly press the power button 5 times | Switching on: hold down the button until the green LED flashes)
