Brewfatherlog is a small tool to synchronize the temperatures of your Grainfather fermenters to Brewfather.

Brewfatherlog can be installed via cargo with:

cargo install brewfatherlog

You can also get a binary from the releases page.

On the first run Brewfatherlog will create a configuration file in your configuration directory. Brewfatherlog will tell you where the configuration file is. You will need to edit that file to configure authentication for both Grainfather and Brewfather.

In Brewfather you need to enable the "Custom Stream" integration in the settings page and put the logging id in the configuration file.

To make Brewfatherlog a systemd service that will start automatically create file /etc/systemd/system/brewfatherlog.service with the content (replace the user and the path to the brewfatherlog binary):

[Unit]Description=Log temperatures from grainfather fermenters to brewfather After=network.target [Service]Type=simple Restart=always RestartSec=1 User=<USER> ExecStart=<PATH TO brewfatherlog> [Install]WantedBy=multi-user.target

and then enable and start the service:

systemctl enable brewfatherlog systemctl start brewfatherlog
