atlas scientific sensors esphome

[mike84]

still haven't got around to trying to figure out how to cal in home assistant, i just calibrate it with a arduino plugged in and use serial monitor in arduino ide. But there must be a easier way though

Any progress with calibrating withing esphome?
I finally got my Ufire ph and ec probes to work so I'm now trying to figure out the calibration procedure

Hi guys,

Great information on getting these sensors up and running in ESPhome but I am having a little trouble:

I can see that the sensors are working in the ESPhome logs but don't know how to add them as entities in HA.

[16:34:45][D][sensor:092]: 'pH': Sending state 5.77700 pH with 2 decimals of accuracy
[16:34:56][D][sensor:092]: 'EC CN': Sending state 829.29999 CN with 0 decimals of accuracy
[16:34:58][D][sensor:092]: 'RTD Temperature': Sending state 20.14200 °C with 2 decimals of accuracy

I have enable newly discovered entities enabled in esphome.

I have another esp8266 which is up and running and can see all 5 entities connected to that one.

Any help would be much appreciated.

All sorted, I removed the esp from esphome and reinstalled it and all entities showed up!

Nicely done.

I'm guessing that Calibration with Arduino IDE is going to get wiped when you setup the ESP in ESPhome, please correct me if I'm wrong?
I calibrated EC probe in Arduino IDE then setup the same esp in ESPhome and cal was out. 12,880 was reading 10,880 and 80,000 was reading 67,610 - I would love to know how to compensate for this in ESPhome.
One other thing that I would like to know how to do is be able to divide the reading by 1000 so that I am getting the correct EC output.

I Would definitely be keen to be able to calibrate through HA.

This worked for me:

Code: Select all

  - platform: ezo
    id: ec_ezo
    name: "EC CN"
    address: 100
    accuracy_decimals: 2
    unit_of_measurement: "EC" 
    filters:
      - lambda: |-
          if (x > 0.1) {
            return x / 1000.0;
          }

Hello guys,

I have Ph controller program running on an Arduino with an Ezo sensor i2c.

I'm trying to add this Ph integration Esp32 but keep running into issues. The logs are stating :

[18:18:11][W][i2c:067]: Too much data to fit in transmitter buffer for address 0x63
[18:18:12][W][i2c:086]: Requesting 20 bytes from 0x63 failed!
[18:18:12][E][ezo.sensor:049]: read error

Strange part is the address for the sensor is set to 99 in the code. Are there any prerequisite files I need to make this work. I've copied ssieb's custom component folder. Am I supposed to add an includes line in the beginning? I've tried adding "includes: custom_components" but nothing. One of the files contains a esphome/core.h file that I definitely don't have. Checking github it says no longer used.

Scratching my head on this one.

anyone tried this new method ?

did you scan to make sure of the address ?

i assume you are flashing the esp32 via usb from the esphome addon on HA ?
