Can't see devices in Domoticz(Newbie)

  • Hi,

    I have a problem with seeing my nodes as devices in Domoticz.
    I can see them in my hardware setup but not in my devices. Maybe I missed something?

    Got a clone nano as gateway and a clone uno as sensor node just for testing. I'm going to run it on a rpi but for now it is on my laptop.

    I hope someone here can help me out.

    Thank you,

    @uncensored you need to receive some information from the sensor before it shows up in Domoticz.
    If you are not sure, please post some more information, like serial log of the node.

  • well the only log i can find is the log of domoticz, don't know if you mean that. can you maybe tell me where i can find the serial log of the node?

    strange thing is that he can't see my Temperature and Humidity sensor but only when i reboot the arduino of the sensor.

    Thank you for the fast reply!

    @uncensored From this log I can read that "Node 1" presents itself but no values are sent. That could be the reason for not showing the devices. At least the node is connecting to the Gateway.

    The "serial log" can be found when you connect the node via USB and look at the arduino serial monitor . Something like below. Also post your sketch and include it in code marks:

  • Well... I did the arduino monitor but got something strange... Not at all what you have...


    And i just got the code from mysensors. only needed to download the DHT.h library, got it from mysensorsarduinoexamples zip file.

    Thank You for helping me. Must be frustrating helping a total newbie 😅

     * The MySensors Arduino library handles the wireless radio link and protocol
     * between your home built sensors/actuators and HA controller of choice.
     * The sensors forms a self healing radio network with optional repeaters. Each
     * repeater and gateway builds a routing tables in EEPROM which keeps track of the
     * network topology allowing messages to be routed to nodes.

  • got it, had to change symbol rate

    i gues there is something wrome with my sensor...
