sending data to thingsboard.io

[gdimaria]

They support MQTT so you should be good to go. You will need a broker somewhere, if it is locally then you can use LM broker app.

If I put LM and Thingsboard VM under the same Zerotier network, can I use LM MQTT Broker app?

In that case, how I can let TB to send write commands to LM?

Right now I only use a script to send values to TB:

Code:

indirizzo = event.dst

tagEvento = event.tag
--log (event)

--broker = "demo.thingsboard.io"
broker = "xxx.xxx.xxx.xxx"
port = 1883
token = "xxxxxxxxxxxxxxxxxxxxx"
topic = "v1/devices/me/telemetry"


value = event.getvalue()


if value == true then
    value = 1
elseif value == false then
    value = 0
else

    numero = tonumber(value)
    if numero ~= nil and numero % 1 ~= 0 then
        value = string.format("%.1f", numero)
    end
 
end

value = tostring(value)


old_value = storage.get(indirizzo,"")


if value == old_value then
 
  --log("return")
 
  return
 
end

storage.set(indirizzo, value)


payload = '{"('..indirizzo..')":' .. value .. '}'


mqtt = require("mosquitto")
client = mqtt.new()

client.ON_CONNECT = function(status, rc, msg)
  if status then
    --log("mqtt connected: "..payload)
    client:publish(topic, tostring(payload))

  else
    log("mqtt connect failed " .. tostring(msg))
    client:disconnect()
  end
end

client.ON_PUBLISH = function()
  client:disconnect()
end

-- client:login_set(username, password)
client:login_set(token, nil)
status, rc, msg = client:connect(broker, port)

if status then
  client:loop_forever()
else
  log('connect failed: ' .. tostring(msg))
end

How should be to receive commands?

Thanks a lot!
