    Hello.
    I have made an energy meter for a heat pump using the Fibaro FGBS-001 Universal Binary Sensor to count pulses from the WZE1 single phase meters. There are two energy meters in front of the pump one for the pump the other for the heater. Unfortunately, the pulses from the counters (open collector) are too short (90 ms ) for the UBS to see them, so I used an NE555 relay module which allowed the pulse to be extended to approximately 500 ms. It works and counts .
    The problem now is the lack of temperature measurement by the DS18B20 sensors plugged into the same Universal Binary Sensor , the measurement hangs up when I connect the module to the IN1 OR IN2 input . The Universal Binary Sensor and the NE555 module are isolated from each other , each has its own power supply and the signal to the IN1 and IN2 inputs are fed from the relays of the NE555 module.
    Any idea why this is happening , how to solve the problem ????
