Sensors have been connected after inclusion
Sensors must be connected to the Universal Binary Sensor before the Universal Binary Sensor is included in the Z-Wave network. Please remove the Binary Universal Detector from the network and include it again.
2. The power supply is inappropriate.
Since DS18B20 sensors are sensitive to network noise, the power supply must be correctly stabilized. Test it with another power source like the one for laptops (with the appropriate output voltage value) to make sure the problem is not with the power supply.
3. The wires connecting the sensors to the Binary Universal Detector are too long
The maximum length of the wires between the detector and the DS18B20 sensors must not exceed 30 m. But this value may vary depending on the wire used and the characteristics of the electrical network.
4. The wires connecting the sensors to the Binary Universal Detector are misplaced
Wires should not be placed near other circuits, especially near AC power grid wires. If you have no choice of location, make sure they are well insulated.
