1 Wire UniPi Sensor Temp Humidity DHT22/AM2302



  • Hallo,
    the temperature sensor DS18B20 works fine with the Evok software and UniPi. Also the calling with jsonrpclib works.
    I put the sensor DHT22/AM2302 on the 1 Wire port how in http://unipi.technology/wiki/1Wire_topology with 4.9 kOhm
    pull up on Vdd.
    I can not calling the sensor + the sensor address isn't in the evok websurface.
    Thanks for a helping hint.

    With best regards

  • The thing is that this sensor does not communicate over the 1-Wire bus…



  • in the technical specification is the statement:
    "Output signal | digital signal via 1-wire bus" …
    what is correct ?
    Is the sentence of the next page the solution ?
    "1-wire bus is used for communication between MCU and AM2302. (Our 1-bus is specially designed, it's different from Maxim/Dallas 1-wire bus,
    so it's incompatible with Dallas 1-wire bus.)"
    Which temperature and humidity sensor works with the UniPi API ?
