I thought you were talking about the pressure sensor!?
Of course i’ve read that documentation, but again I am using a 1118, and not much documentation. I was told they were the same …but they are not… i found my way though.
i think that i would get better results if I could get more info about the actual sensor, the pressure sensor!
;’)
Yes it would be good if you have the documentation of your sensor, but it is not necessary. You can instead test what voltages you get at various depths.
My reference to documentation was for your question on the gain factor 
so what else would you need appart from the voltage measures that i already provided then, you lost me a little…
/fab
Well basically if I understand correctly in your case the max voltage you will be reading is 0.730v.
So based on the documentation I think you should set a gain factor of 1.024
ok cool, but from voltage how do I get to the desired volume or percentage: I know I’m that bad in maths…
This code will get you a sensor which shows the centimeters:
- platform: template
name: "CM"
id: watertank_cm
icon: 'mdi:water-well'
unit_of_measurement: 'cm'
lambda: |-
return id(watertank_voltage).state;
update_interval: 1s #the delta filter will ensure it only sends values when something changes.
filters:
- calibrate_linear:
# Measured value of X volt maps to y cm
- 0.464 -> 0
- 0.994 -> 55.2
- 1.424 -> 102.0
- 1.818 -> 144.0
- delta : 0.001 #only send the result if the difference with the last sent result is higher than this
This code will give you a percentage of how full your tank is:
- platform: template
name: "usable %"
id: watertank_percent
icon: 'mdi:water-well'
unit_of_measurement: '%'
lambda: |-
return id(watertank_cm).state / 165.0 * 100;
#divide by max water level height to get a percentage
update_interval: 1s #the delta filter will ensure it only sends values when something changes.
filters:
- delta : 0.001 #only send the result if the difference with the last sent result is higher than this
This code will give you the liters:
- platform: template
name: "usable liters"
id: watertank_liter
icon: 'mdi:water-well'
unit_of_measurement: 'l'
lambda: |-
return id(watertank_cm).state / 100 * 3.14159265 * 1.13751599 * 1.13751599 * 1000.0;
#height (meters) times pi times radius (meters) squared times 1000 gives liters. This works if your water tank is a cilinder shape. Otherwise you have to use different calculations.
update_interval: 1s #the delta filter will ensure it only sends values when something changes.
filters:
- delta : 0.001 #only send the result if the difference with the last sent result is higher than this
where did you get the documentation, i didn’t get any with my sensor
still getting timed out all the time, i get no readings at all, even when i copied your conf.
I can’t be that unlucky to have bought 3 faulty sensors in a row… it must be something else. i’ll paste my esphome log and my config, maybe you’ll spot something I dont see.
thank you

For the Ultrasonic sensor i’m guessing that this is my problem: “Filtering pulses shorter than 13 µs”
for the flowrate sensor and the pressure sensor, they were working earlier but it just stopped, maybe i should just keep one “- platform:” for each… anyways, one problem at a time.
anyone notice something wrong in there, cuz it aint working, and it was before, i am starting to freak out!
Oh yeah I know i’ve gotten all the info I need for this one but not the 1118, I am using the 1115 with the pressure sensor
Yes I’m also using the 1115
I wonder why my numbers fluctuate this much?
that was all day and pump was turned on twice only!
any help is obviously welcomed!
how did you obtain this info, I want to know how you ended up with these numbers, i am lost a little bit as ti where does this info come from? I would like to be able to get it myself to understand how to get it etc…
I realise there’s two simultaneous discussions in this thread.
#1 The ADS1115 + pressure sensor without documentation at all to get volts to then get volume etc…
#2 The JSN SR04T - 2.0 to actually get the same information.
which one should I keep here and which one should I start a different thread?
Hello, Did you solve the problem, time out…
you forgot in the code timeout: 2.5m the max is 4.0m (eter)
No i never got it working proprely, i mean its measuring voltage, but i cant figure out the way to accurately get then volume from it.
what do you mean:
i forgot 2.4 the max is 4??
you noticed an error in my code?
Hello, i’ve tried same configuration and have same problem of distance Time Out. I only have one ultrasonic sensor, si the problem could be the sensor itself. I might give a try at HC-SR04 sensor but as i will use or for water level purpose outsider of the house water resistant might be mandatory
For those following this thread - try the solutions offered at the following thread.
ESPHome water level sensor
I switched to HC-SR04 sensor, and it’s working flawlessly. The problem was the sensor. So i’ll go with the non-water resistant one for now and will see how much time it will work.
