System settings

The Settings tab on the System & diagnostics page holds the settings for the whole controller.

Global settings#

Temperature unit is Celsius or Fahrenheit, for the admin page, the reports and Home Assistant. The controller keeps its settings in Celsius, so changing the unit doesn't change any of them. Save or discard any other unsaved changes first.
Probe resolution is how finely the temperature probes measure: 9 bit is to 0.5 °C, 10 bit to 0.25 °C, 11 bit to 0.125 °C and 12 bit to 0.0625 °C. A finer reading takes the probes longer.
Alarm delay is how long, in seconds, a fermenter can be outside its floor or ceiling by less than its alarm tolerance before the alarm goes off. Up to 3600 seconds. See Fermenter settings.
mDNS discovery gives the controller its ourbrewbot-xxxxxx.local name on your network. A change takes effect after a restart.
Check for firmware updates checks once a day whether a newer OurBrewbot is out, and shows it on the Firmware tab and in Home Assistant. It sends ourbrewbot.com the controller's chip ID and firmware version, and nothing is installed by itself.
Send crash reports sends the details of a crash to ourbrewbot.com after the controller restarts from one, to help fix the bug. They contain technical details of the crash. Neither this nor the update check sends your settings, your WiFi network's name or password, or any temperatures or brewing data.

The README lists exactly what the update check and crash reports send.

Debug mode#

Enable debug mode adds Open debug overrides to each fermenter's settings, for trying out how a fermenter behaves with readings you type in. Press Apply debug mode to switch it on or off. It's switched off again when the controller restarts.

Remote syslog#

Syslog sends the controller log to a syslog server on your network, to keep a permanent record of it.

Server host is the syslog server's address, and Port is usually 514.
Facility labels the controller's messages on the server.
Minimum level leaves out messages less important than the level you choose. Debug sends everything.
