hi, thankyou for reply, now my project is control streetlight using lorawan. i wanted to send data from openremote to chirpstack using MQTT. i follow this steps to get data from chirpstack to openremote via chirpstack, and it work perfect Tutorial: Receive LoRaWAN sensor data from ChirpStack · openremote/openremote Wiki · GitHub
so now i can get brightness value when i send hex command from chirpstack
subscription topic is running well, now my problem is in the publish topic. the goal is i need send the brightness value to chirpstack based on slider value on openremote.
for publish topic, i also try build on node-red and running well, data can send to chirpstack and execute command
and this is screenshot for publish function
i also get information for payload command from nema lorawan streetlight vendor (which is sensor for this streetlight)
so i wanted to “get value from slider”-> “and i will make a function to transform into hex command based on payload inside openremote like i made function in node red” → " publish that command to chirpstack through MQTT when i slide "
