Observations after installing the device (based on Sigalou's documentation)
- "Liquid depth max" is the actual max liquid level (distance from the bottom of the tank to the max level). The comment "Height from sensor to liquid level" is incorrect.
- "Liquid Level %" is relative to "Liquid depth max".
- "Mini set" and "Max set" are both relative to "Installation height".
Example:
- Sensor installation height: 1.70 m (from bottom of tank)
- Max water level: 1.65 m
- Settings:
- Max set = 97%
- Mini set = 5%
- Installation Height = 1.70 m
- Liquid Max Depth = 1.65 m
- Liquid state = "low" below 0.085 m (8.5 cm) → 1.70 × 0.05
- Liquid state = "high" above 1.65 m → 1.70 × 0.97 (prevents overflow)
- Example reading: water level 1.42 m → sensor reports 1.42 m, 86% (1.65 × 0.86 = 1.419 → 1.42), liquid state = "normal"
Exposes
Liquid level percent (numeric)
Liquid level ratio. Value can be found in the published state on the liquid_level_percent property. It's not possible to read (/get) or write (/set) this value. The unit of this value is %.
Liquid depth (numeric)
Liquid Depth. Value can be found in the published state on the liquid_depth property. It's not possible to read (/get) or write (/set) this value. The unit of this value is m.
Liquid state (enum)
Liquid level status. Value can be found in the published state on the liquid_state property. It's not possible to read (/get) or write (/set) this value. The possible values are: low, normal, high.
Max set (numeric)
Liquid max percentage. Value can be found in the published state on the max_set property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"max_set": NEW_VALUE}. The minimal value is 0 and the maximum value is 100. The unit of this value is %.
Mini set (numeric)
Liquid minimal percentage. Value can be found in the published state on the mini_set property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"mini_set": NEW_VALUE}. The minimal value is 0 and the maximum value is 100. The unit of this value is %.
Installation height (numeric)
Height from sensor to tank bottom. Value can be found in the published state on the installation_height property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"installation_height": NEW_VALUE}. The minimal value is 0.1 and the maximum value is 4. The unit of this value is m.
Liquid depth max (numeric)
Height from sensor to liquid level. Value can be found in the published state on the liquid_depth_max property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"liquid_depth_max": NEW_VALUE}. The minimal value is 0.1 and the maximum value is 4. The unit of this value is m.
