Control by MQTT

    • Autor

    Hi,

    I have successfully connect my PLUS 1PM to my broker. (screenshot 1)

    All I want to do with this device is to activate and deactivate the relay by MQTT. All the other things I don't need. I will also never subscribe to any topic of this device.

    But I find as good as NO info about the topic and payload to do this.

    What I did found is that the topic should be: shellies/zwembad/relay/0/command and the payload simply on or off

    But this does not work.

    I do receive messages, but on completely different topic structures (screenshot 2)

    Do I need to do scripting to get started with MQTT controlling the device?

    Long story short: I have 1 (new) shelly device, what is the topic and payload to control the relay?

    Thanks

    example for mosquitto_pub, message (-m) has to be JSON.

    Code
    mosquitto_pub -h localhost -p 1883 -u admin -P admin -t zwembad/rpc -m '{"id":124, "src":"zwembad", "method":"Switch.Set", "params":{"id":0,"on":true}}'

    >100 Shellies, darunter so gut wie alles was der Hersteller produziert hat. ;)

    Thanks,
    you have put me on the right way.

    The documentation is really confusing, but finally, with copy-past and a lot of testing I found the right topic and payload.

    Topic: zwembad/rpc ==> Where zwembad is the configured device name, don't forget the /rpc
    Payload: {"id":1, "src":"PFC100", "method": "Switch.Set", "params":{"id":0,"on":true} } ==> Where the first ID and SRC is something you choose, this comes back in the confirmation message.

    Hello,

    i am trying for some hours to do the same - switching the relay from MQTT, but it does not work.

    in my opinion i am using the same "order" as Nick - but the relay does not switch...

    is there anything else to configure on the ShellyPlus1PM?

    Code
    mosquitto_pub -t 'shellyTest/rpc' -m '{"id":124, "src":"shellyTest","method":"Switch.Set", "params":{"id":0,"on":true}}'

    with the http commands it works fine - both possibilites known to me work:

    Code
    http://192.168.2.xxx/relay/0?turn=on
http://192.168.2.xxx/rpc/Switch.Set?id=0&on=true

    getting status infos like power and energy via mqtt works also fine only relay switching does not...

    thynk you for your help,

    Karl

    Additional Information:

    Every Shelly device publishes and subscribes to specific preset topics, such as "command/switch:0" or "shellys/command..." You can control your Shelly devices by sending your commands to these specific topics. For "command/switch:0," your payload should consist of "on" , "off" or "toggle". All Shelly devices are listening to the "shellys/command" topic, so publishing commands there can be useful for executing bash commands like updating all devices, and nice other purposes.

    I initially searched for instructions on how to use them and stumbled upon this post. However, through some trial and error, I managed to make it work. I hope that anyone who finds themselves in a similar situation through a Google search can now save some time. ;)
