• Compiled the humidity sketch. Looking at the output of serial monitor i see messages as

    send: 11-11-0-0 s=0,c=1,t=1,pt=7,l=5,sg=0,st=fail:53.1
    H: 53.10

    So everything seems working except the string st=fail:53.1

    As i understood from the API - it's the submessage type which gives the fail? What might have went wrong?

    Hi @moskovskiy82!

    st=fail" means the receiving node or gateway has problems sending ack back to the sending node.
    Try adding a capacitor to the receiving radio, change powersource, move reciever/sender closer to eachother or build a repeater.

  • The only thing i have changed from the stock sketch is this as i'm using openhab and wifi mqtt client gateway

    It has probably nothing with the sketch to do - its hardware (Range/Power issues).
    If you think its a software issue, try clearing the eeprom and reupload your sketch.

  • You know that your node is also acting as a repeater? If that's not what you want, you need to do


  • i Know it's in repeater mode.
    I couldn't find any downsides in turning it on except that the sleep function had to be disabled. It still acts as a sensor node
