Hello,
I built a level sensor for my cistern with the Shelly uni.
How can I integrate the Homeassistant in such a way that I get a percentage display of the maximum?
I have attached a drawing for the construction of the Shelly. The values are queried via the ADC output of the Shelly Uni.
Hi,
you have probably resolved this in the meantime but anyway.
Adding two sensors to the HA instance (cm and %) based on ADC voltage sensor assumed 0 - 10V measuring range for 200 cm depth water sensor and entity called su_water via configuration.yaml.
I don’t know how to prevent rounding of ADC sensor by the integration - it is rounded to one decimal by default.
- platform: template
sensors:
su_komin_water_pct:
friendly_name: "Water LVL pct"
unique_id: water_pct
unit_of_measurement: '%'
value_template: "{{ (states('sensor.su_water_adc') | float * 100 / 10) | round (0) }}"
su_komin_water_lvl:
friendly_name: "Water LVL cm"
unique_id: water_cm
unit_of_measurement: 'cm'
value_template: "{{ (states('sensor.su_water_adc') | float * 200 / 10) | round (0) }}"
i am not an expert in electronics so i need to make these stupic questioin to get it right.
the sensor (+) is connected to Uni’s VCC
the sensor (-) is connected to Uni’s GND Sensor
the power supply (+) is connected to the pump (+) and the Uni’s VCC
the power supply (-) is connected to Uni’s ADC and (via a 250 or 500 Ohm resistor) to the cable connecting the sensor (-) to the Uni’s GND sensor
am i getting this right?
also, what if I put a 560 Ohm resistor?
any help from anybody??
I have the same problem as you - did you manage to set it up (yaml part I meen)?
