NetatmoRemoteTemperature

This project would like to resolve the problem related to not accurate temperature retrieved by radiator's sensor installed on valves. The problem is not related to netatmo sensor quality but to the nearness of the sensor to the radiator. To achieve this target the solution use a remote temperature sensor for each valve and one single hub that receive all sensor data, save history and call netatmo API.

Network Layout

Technology used:

• Asp.Net Core 2.2 / Docker / Raspberry pi 3
• ESP8266 / Arduino C++
• Netatmo public API
• SPA / Angular7 / ngx-admin / node-nginx / Docker

Remote Sensor

• Arduino compatible board (Esp8266) to retrieve temperature and humidity (DHT22) or only temperature (DS18B20).

Main activities:

• Read Temperature \ Humidity
• Read battery level
• Connect to WiFi
• Send data to Rest API
• DeepSleep

Technology used:

• ESP8266 / Arduino C++
• DHT Library
• OneWire \ Dallas Library
• ADC to check battery level
• DeepSleep

Hardware

• LOLIN D1 MINI PRO v2 - 4,00 €
• DHT22 or DS18B20 - 1,80 € / 0,50 €
• Lithion Battery 18650 3000ma - 4,00 €
• Other parts (box, battery holder, etc..) 2,00 €

Total price of around 11,00 € for each room\sensor (AliExpress)

Compile & Install:

• Install Arduino IDE 1.8.6
• Open /RoomTempSender/RoomTempSender/RoomTempSender.ino
• Use "Manage Libraries" to add the required libraries (ArduinoJson 5.13.5, Adafruit DHT sensor library 1.2.3
• Change the source code with network SSID, Password and TemperatureHub endpoint
• Compile and upload to the device

Use:

• Remember to close the jumper after downloading the firmware into the board to awake from the deep sleep and to read the battery level. If you close the jumper for deep sleep you can't download the firmware.

• Schema to connect the DS18B20 with the ESP8266 (in this case a NODEMCU). The components are Dallas DS18B20 temperature sensor and 4.7K resistor.

• Every 10 minutes the system send to TemperatureHub all sensor data and goes into deepsleep. The remote sensor consumption during works is around of 78ma while during deep sleep the consume is around of 0,067ma. The target goal is to recharge the battery every 50/60 days

Temperature Hub

• Asp.net core 2.2 webapi application to save on SQLite all temperature retrieved.
• Switch to manual and set new temperature target based on remote temperature maintaining the scheduled target temperature

Main activities:

• Receive Remote Sensor Data
• Read Netatmo Schedule (Cached)
• Read Netatmo Valve Sensor Data (Cached)
• If needed change Netatmo Target Temperature

Technology used:

• Asp.Net Core 2.2 / Cache / Sqlite / Docker / Raspberry pi 3
• Netatmo public API

Hardware

• Raspberry Pi 3
• PowerSupply
• Case
• MicroSD 16Gb

Total price of around 57,00 € (Amazon)

Compile & Install:

• On PC

  • Install\Check Visual Studio 2017
  • Install\Check .net core 2.2
  • Install\Check Docker for Windows
  • Clone Git Repo
  • Move on /TemperatureHub
  • Run docker build -t sensordata .
  • Save image as tar docker save sensordata > sensordata.tar
  • Move tar file on Raspberry (ex. WinSCP)

• On Raspberry

     curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh
     sudo groupadd docker
     sudo gpasswd -a $USER docker
     restart
    

  • Load Docker image docker load < sensordata.tar
  • Run Docker container (fill empty field)

    docker run -d -v ~/SensorData:/app/AppData  -p 5000:5000 -e TZ=Europe/Rome -e AppSettings:clientId='' -e AppSettings:clientSecret='' -e AppSettings:username='' -e AppSettings:password='' -e AppSettings:homeId='' --restart=always sensordata
