2019 May IoT project

As I previously posted, I made a WiFi AC remote controller project. see telegram bot for HVAC

Today, I begin a new project to go further.

I purchased another Raspberry Pi 3 Model B, AND Raspberry Pi Sensor Kit. (http://m.eleparts.co.kr/goods/view?no=3730500 and http://m.eleparts.co.kr/goods/view?no=3030452)

(I just wanted to purchase sensor only, but I can’t sure, I could attach these sensors to my existing RPi, so I posted a question to a forum https://www.cooking-hacks.com/forum/viewtopic.php?f=43&t=19434&sid=d89e064868d4a0dce0c58ea7a6490bde)

And, I tested DHT11 as https://github.com/deokgonkim/rpi_sensor


My next step will be,

1. set up a messaging queue, like Rabbit MQ

2. set up a web/api server for gathering the data and the controll center.

3. my existing bot code shoud be migrated to a new server, and these two RPi should listen to MQ for commands, and should send data to MQ.


To be continued…



yum install rabbitmq-server

pip install pika






Ok, I guess I can do, (first, I need to know the pin)


And It works,

And the codes,


To be continued.



I switched MQ from direct queue to fanout-exchange.

I defined protocol, for extensible.

I prepared persistent storage. RDB.

so the code. https://github.com/deokgonkim/dgkimnet-homeserver/commit/cc46a6b67904dd8a54466b30499119748dbf3304

To be continued…



Just, server project, progress. one milli-codes?




Finally, the original idea has completely implemented.

  1. 빠른 답변 감사합니다. 간단한 얘기를 나누고 싶은데 혹시 가능할까요?? 이러한 사이트개발에 관심이 있습니다. 저는 약사구요. 약사들을 위한 저런 사이트를 만들어 보고 싶습니다.

  2. 그런데 주신 링크를 따라 들어갔는데 오픈소스인데 어떻게 사용하죠… 공식사이트도 접속이 안되네요.

  3. 예. 아쉽게도 더이상 공식 사이트는 운영되지 않고 있는 것 같으며, 기능이 유사한 다른 소프트웨어를 찾아 보면 비슷한 것이 있을 것입니다. 구글에서 osqa alternative 같은 것으로 검색을 하시면..

  4. 혹시 간단한 얘기를 나누고 싶은데…카카오톡 아이디라도 혹시… 가능할까요…
