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!
