OurBrewbotHome Assistant
Enable MQTT in the admin page and point it at your broker. With HA Discovery turned on, the controller announces itself to Home Assistant whenever it connects and whenever Home Assistant restarts. Entities then appear with no YAML to write.

| OurBrewbot (controller) | sensor | firmware version, IP address, mDNS name, WiFi SSID, RSSI, free heap, uptime, chip ID, reboot reason and code |
| button | reboot, all off | |
| OurBrewbot F0–F3 (fermenters) | sensor | beer and ambient temperature, gravity and its source, attenuation, status, profile step |
| binary_sensor | alarm | |

| number | ceiling and floor temperature, hysteresis, compressor delay, OG, TG | |
| text / select | name, beer name, yeast / profile number | |
| OurBrewbot Probe | sensor, binary_sensor | temperature, name, function, fermenter / active |
| OurBrewbot Tilt | sensor, binary_sensor | temperature, gravity, fermenter, function / active, is Pro |
| OurBrewbot iSpindel | sensor | temperature, gravity, corrected gravity, battery, RSSI, angle, run time |
Controlling from Home Assistant#
By default, Home Assistant can only read values. To let it change settings, turn on
Allow HA Control in the MQTT settings. The controller then accepts commands on
<baseTopic>/+/+/set for switches, numbers, text, selects and buttons. It
ignores out-of-range values, and the entity goes back to the real value within about a minute.
Dashboard#
A ready-made dashboard is in
HomeAssistant/dashboard.yaml.
It uses the Plotly graph,
Mushroom and
card-mod cards from HACS.
