      Hi,

      I have developed a new MQTT bridge to convert from serial, ethernet to MQTT.
      Supports for MySensors.
      You can have more than one serial ports and/or ethernet connections.
      If you are interested in, https://github.com/mycontroller-org/2mqtt
      Thanks!

        Hello @jkandasa,

        I was testing if I could use the old workflow that we used in our weather station school project, using an Arduino with RFM69 radio as a serial gateway broadcasting messages to local Mosquitto MQTT broker from where MyController then picks up the messages.

        I noticed that compared to your new v2 MyController's internal serial gateway, your 2mqtt bridge consumes more CPU cycles.

        Compare that when your builtin serial gateway is enabled from within MyController v2 UI with low CPU usage:
        MyController-SerialGW.png
        to your standalone 2mqtt bridge with higher CPU usage:
        MyController-2mqtt.png

        And I double checked that the builtin serial gateway was disabled from within the MyController v2 UI. I even tried to terminate MyController and checked with MQTT.fx if data was incoming from the bridge and I can confirm that I was still receiving valid data besides the high CPU usage.

        I was using your suggested settings as mentioned in your documentation MySensors | MyController.org and from your readme file on 2mqtt/README.md.

        Is this normal, or should I file a issue on your GitHub repository?

        Kind regards

          Hi, @j54n1n Thanks for the detailed report.
          It does not look normal. It can be a bug in 2mqtt
          Can you share your configuration details used in 2mqtt? (remove sensitive details)

            @jkandasa yes sure, I was not using any special configuration. I adapted the config file only to suit the configuration that we used before.

            Here we go for the config.yaml file:

            logger:
              mode: development
              encoding: console
              level: info
            
            adapters:
              - name: adapter1
                enabled: true
                reconnect_delay: 20s
                provider: mysensors_v2
                source:

                        @jkandasa thanks, yes now I get low CPU usage.

                        Nice work ^^

                          I believe I my change will not impact the functionality
                          Please let me know if you see a different behavior in the recent build 🙂

                            @jkandasa Ok, I quickly looked through it with MQTT.fx and it seems to be fine.

                            Thanks again. Now I will start looking for strange behaviors with MySensors in your MyController v2.
