Програмные компоненты

Устройство умеет отображать время, погоду, текстовое сообщение, картинку. Легко может быть расширена добавлением новых типов информации в обрабтчик сообщений :

mqtt:on("message", function(conn, topic, data)
--    tmr.stop(1)
    local start = tmr.now()
    print(topic,node.heap())
            if  topic:match('weather$') then
                dolc('weather',data)
            elseif topic:match('message$') then
                dolc('message',data)
            elseif topic:match('image$') then
                dolc('image',data)
            elseif topic:match('gird$') then
                dolc('gird')
            elseif topic:match('test$') then
                dolc('test',data)
            elseif topic:match('setTime$') then
                dolc('settime',data)
            elseif topic:match('save$') then
                dolc('save',data)
            end

--    print(node.heap(),'bytes',tmr.now() - start, 'miliseconds', topic)
    
--    mqtt:publish('oled/status',cjson.encode({tstamp = tmr.time(), data = {memory = node.heap(),miliseconds = tmr.now() - start, topic = topic }}),0,0)
    data = nil
    topic =nil
         
    collectgarbage()
end)

Для управления используется потоки на Node-RED
