Home Assistant
AquaChemD publishes MQTT Discovery information so its sensors, dosing state and safety conditions can appear in Home Assistant.
Chemistry sensors
| Entity | Unit | Metadata documented by project |
|---|---|---|
| pH | pH | state_class: measurement |
| ORP | mV | Measurement; voltage device class is documented as an option |
| Temperature | °C / °F | device_class: temperature |
Dosing consumption
Doser totals are published as volume values such as total_acid_ml and total_chlorine_ml. The project documentation describes using Home Assistant Utility Meter with delta values to accumulate dose events.
Safety conditions
Binary flow/level and other interlock entities can be represented as problem, motion or moisture-style entities depending on the meaning and desired Home Assistant presentation.
Doser controls
The project documents an Auto/Enabled/On/Off style mode rather than treating every doser as a simple binary switch.
