Dallas DS18B20 temperate sensor



  • Hello

    This is my first project with a Ds18B20 an arduino mega as that is what I had to hand as a test as well as a nrf24l01 radio. This is all being transmitted to a raspberry pi gateway with a nrf24l01 with the eventual plan to link to hass io.

    I am unfortunately stuck with making sure the value is transmitted to the raspberry pi. I am using the code detailed here [https://www.mysensors.org/build/temp] (https://www.mysensors.org/build/temp)

    I have added the extra definitions needed for the mega and connected the radio as per [https://www.mysensors.org/build/connect_radio] (https://www.mysensors.org/build/connect_radio)

    This is the debug message from my raspberry pi, I tried using the log parser but it was not clear what the sensor output was and if this was right. Please could someone help me as to if this is right?

    Welcome to the forum @Jenkins

    Are you sure this log is from the Raspberry Pi gateway? It looks like a node log.



  • Hello @mfalkvidd

    Thanks for the reply, I reread the instructions https://www.mysensors.org/build/raspberry and ran the following commands.

    git clone https://github.com/mysensors/MySensors.git --branch development
    cd MySensors
    

    The choice of these commands was based on wanting to use the raspberry py to recive information on the nrf24l01 chip and share it on an ethernet gateway.

    ./configure --my-transport=rf24 --my-gateway=ethernet --my-port=5003
    
    make
    
    sudo ./bin/mysgw
    

    This was the output I got with the sensor on the arduio already on and running the code.

    I will continue to also read other posts to see if I can find my error. Thank you for your help.

    Sorry, my bad. It is clearly a gateway log.

    The first line here shows that the gateway received a message from node 3.
    The message is a Find Parent request, which means node 3 is asking for the gateway.
    The last line is the gateway sending a response. The ! before TSF and the st=NACK means that the gateway sent the message, but the gateway did not receive acknowledgement from the node that the node received the reply.

    The most common cause is unstable power supply. What capacitor(s) are you using? (On the Raspberry and on the node). How is the nrf powered on the node?

    If you haven't already, see https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to troubleshoot them efficiently.



  • Hello

    Before my post was approved last night I did realise I was missing capacitors on the rf24 modules. The node has the rf24 module powered from the 3.3v pin of the arduino mega. The raspberry pi gpio 3.3v is powering the other rf24. I have ordered some capacitors so will see if that helps when they arrive sometime next week.

    Thanks for the help



  • Hello,

    The Capacitors took a lot longer than they should due to the post being slow at the moment. But I think it now works, here is a trace do you agree?
