Thermometer log

A platform for logging temperature using w1_therm thermometers.

Temperature logbook

See logbook.

A server for storing the logs from the devices. It's designed to run on Vercel. It uses AWS DynamoDB to store the data which can be created using terraform (see storage.tf).

Loggers

See logger for the thermometer loggers.

rasbpi_ds18b20 logger

A raspberry PI thermometer that reads the temperature and sends it to a server over HTTP. It is compatible with the w1_therm devices.

black-pill+esp8266_ds18b20 logger

A logger for the STM32F103C8T6 Black Pill with ESP8266 WiFi Microchip.

This doesn't yet send the results to the logbook.

It is built with PlatformIO.

Requirements

This requires the w1-gpio to be enabled and docker and docker-compose to be installed.

The recommended way:

1. Enable w1-gpio

   echo -e "dtoverlay=w1-gpio\n" | sudo tee -a /boot/config.txt
   sudo reboot
   

2. Install docker using the convenience script

   curl -fsSL https://get.docker.com -o get-docker.sh
   sudo sh get-docker.sh
   sudo usermod -aG docker ${USER}
   

3. Install docker-compose requirements

   sudo apt-get install -y libffi-dev libssl-dev python3 python3-pip
   

4. Install docker-compose using pip

   sudo pip3 -v install docker-compose
   

5. Set up a single-node swarm on the Raspberry Pi

   docker swarm init
   

6. Update the environment variables, replacing the <..>s with the correct values:

   THERM_DEV_PATH=/sys/devices/w1_bus_master1/28-<ID>/w1_slave
   THERM_SERVER_ADDRESS=<server-address>
   THERM_LOCATION=<location
   

7. Set up service secret:

   docker secret create therm_auth_secret -
   

Usage

1. Clone this repo
2. Run the following command, replacing with the location of the thermometer, for example "living-room". This should only use a-z characters or hyphens.

   docker stack delpoy --compose-file docker-compse.yml --compose-file docker-compose.prod.yml thermometer
   

Manual testing

docker-compose -f docker-compose.yml -f
