    Hello,
    Short question. Can we increase the number of nodes from 254 to 1024 or more?

    If I understand correctly, this can be done by changing the data type for nodeid. Or is it more difficult?

    Sorry for my English.

      @dmytro-zadvornov You would need to rework the MySensors stack and break the protocol in doing so.
      If you really need more then 254 nodes I would suggest to break it up in separate networks, each with its own gateway.

        Sound good for me. How can I make it if i am using RFM95 LoRa radio?
        I have not found any mysensors instruction which could resolve this.
        Do you have any instruction for this solution?

          May be it could be implemented in a new version of mysensors?

            @dmytro-zadvornov the different networks can use different modem configurations. Documentation: https://www.mysensors.org/apidocs/group__RFM95SettingGrpPub.html#gaedc32edc29ffd4ecc2c849e39010069e

              @dmytro-zadvornov I think you are the first person to ask during the 4 years I have been active in this forum. Could you describe what you are building? Breaking the protocol will be bad for very many users, so it would be good to understand for which cases it would be useful. Hopefully, we can find benefits that outweigh the drawbacks.

                Do not forgot, that some radios ( RFM69 ) allow only 255 address in one network.
                No way connect more nodes to all receiving all messages ...
