Hi friends.
First I want to thank all the members of the LEDgardener forum. Thanks to the information I found in the forum, I managed to integrate and calibrate the EZO-ph and EZO-ec sensors in Tasmota 9.2.
I recommend that the integration of the EZO-ph and EZO-ec sensors be carried out in a NodeMCU v.2 device, I had problems with the integration using the ESP32.
They should also use Tasmota 9.2
The commands used for calibration are:
--------
pH:
Sensor78 Cal, mid, 7.00
Sensor78 Cal, low, 4.00
Sensor78 Cal, high, 10.00
Reference:

---------
EC:
Sensor78 Cal, dry
Sensor78 Cal, low, 12880
Sensor78 Cal, high, 80000
Reference:

-------------
I had the problem that when I calibrated one of the sensors the other was set to 0.00, so I recommend that the calibration be done separately from the other, that is, first connect only the EZO-pH sensor to the NodeMCU V.2 and calibrate, once calibrated disconnect it, then connect the EZO-ec and calibrate it, once calibrated both separately just connect the two sensors to work with them.
It is the way it turned out for me, I hope it helps you.

i have 4 atlas sensors on 1 Mini D1 esp8266 working good since xmas and i calibrate the ph and ec with no issues :

Thanks so much for sharing this i have ben trying to get my hydro kit tuned id but have failed at the ec side
if it's the Hydro Kit from Atlas , works every time for memorrisraybrooks wrote: ↑Thu Apr 22, 2021 3:08 amThanks so much for sharing this i have ben trying to get my hydro kit tuned id but have failed at the ec side
when you have multiple EZOs on the same I2C bus you have to do Sensor78-2 Sensor78-3 and so on ... Sensor78 applies to the first device only , in your case EZO-PH
on my Hydro Kit from Atlas , the EC is the second Ezo Sensor
EC:
Sensor78-2 Cal, dry
Sensor78-2 Cal, low, 12880
Sensor78-2 Cal, high, 80000
