TemperatureSensor give me only 0.0°

[marcobastianon]

hi all, i'm tryng to create a TemperatureSensor using this code:

{
  "DeviceName": "TempStudio",
  "Services": [{
      "ServiceType": "TemperatureSensor",
      "ServiceName": "TempStudio",
      "Characteristics": [{
          "Type": "CurrentTemperature",
          "Listen": ["4/6/6"]
        }
      ]
    }
  ]
}

the thermostat tells me that the temperature is 0.0 ° C and I can't understand where my mistake is. I have the error with both iOS 13 and iOS 14.

in the knx bus @ 4/6/6 i've 24.2 ° C

some one have temperature working on "TemperatureSensor" or "Thermostat"??

Sure I have, multiple of them:

                {
                    "ServiceType": "TemperatureSensor",
                    "ServiceName": "Esszimmer Temperatur",
                    "Characteristics": [
                        {
                            "Type": "CurrentTemperature",
                            "Listen": [
                                "3/1/41"
                            ],
                            "MaxValue": 60,
                            "MinValue": -20
                        }
                    ],
                    "KNXReadRequests": [
                        "3/1/41"
                    ]
                }

with 3/1/41 being a 2-byte float from my Berker B.IQ room temp sensor.

can you help me understending why u add: "KNXReadRequests": [ "3/1/41" ] in my case i cant have the right temperature

[snowdd1]

Sure , it makes homebridge-knx issue a read request at startup, so you don’t need to wait too long to get the value filled.

More important are the min and max settings because the values might otherwise be ignored.

[marcobastianon]

@snowdd1 in you opinion: if i recive this telegram.. homebridge-knx might not interpret it correctly?... in all my test on ets i recive a telegram like this, but on homebridge nothing change..

[snowdd1]

You might want to start homebridge in debug mode and post the log here.

[marcobastianon]

DEBUG=* homebridge &> file.ext

i've a long file, but nothing on temperature, m'i wrong?

[marcobastianon]

i realy can not find a solution.. i see on ets room temp change, but on homekit nothing change..

[marcobastianon]

i can’t understand why all my telegram on with temperature are completely ignored.. con some one help me to find a solution? because i can not use thermostat.

[marcobastianon]

what version of knxd are you using? it seems that my installed version "knxd 0.14.35:fc9ba78" is not compatible with dtp9 .. using "knxtool vbusmonitor1 ip: localhost" I can't see any telegram concerning the temperature, I only see telegrams for switching on lights.

[marcobastianon]

i've solve my problem... :)

as smurfix say me here ""https://github.com/knxd/knxd/issues/488"

"The most common reason this happens is that the physaddr of the sender(s) of these DPT9 messages is duplicated or within knxd's client address range."

i've changed my address range and now all work perfectly !!
