Pool - PH / ORP - Tuya W2839 - Modify datapoint? how?

ESPHome
1

Hi all,

I am having a pool and what to do some automatic watercare.
Means, I need to know PH / ORP.

Therefor, on Reddit, someone modified this W2839 3-in-1- WIFI Tuya device and soldered an ESP12f.
https://www.reddit.com/r/homeassistant/comments/zwv4d5/pool_sensors_orp_ph_and_temp_via_esphome_working/

His config:

esphome:
name: water-ph-ec
friendly_name: Water PH EC
esp8266:
  board: esp01_1m
# Enable logging
logger:
  baud_rate: 0
# Enable Home Assistant API

captive_portal:

# disable hardware logger to free up UART pins
logger:

uart:
  rx_pin: GPIO3
  tx_pin: GPIO1
  baud_rate: 115200

sensor:
  - platform: "tuya"
    name: "ORP_Temp"
    sensor_datapoint: 8
    unit_of_measurement: "°C"
    device_class: "temperature"
    state_class: "measurement"
    accuracy_decimals: 1
    filters:
      - multiply: 0.1

  - platform: "tuya"
    name: "ORP_PH"
    sensor_datapoint: 106
    state_class: "measurement"
    accuracy_decimals: 2
    filters:
      - multiply: 0.01
  
  - platform: "tuya"
    name: "ORP_ORP"
    sensor_datapoint: 131
    state_class: "measurement"

Unfortunately there some more information missing and I am not yet expierienced with the tuya platform.

1.) Does anybody have a good idea how we can calibrate the sensors?
So putting these in some measurement solution of PH 7 and ORP 750mV, I would assume I can adjust the value measured to exactly that.

2.) How would we able to make use of the Plugs?
I assume, when reading the Tuya FAN, this would be a “switch_datapoint:” but not yet known which one right? :frowning:

So is someone knowing how we can find out the datapoints?

Cheers Chris

Replying on my own entry now :wink:

I replaced the chip with an ESP12f.

1.) Calibration is done by the device itself, the original CB3S or my ESP12f is only there for communication, means, calibration as per manual of the device

2.) Plugs cannot be switched, at least I did not find an datapoint for it, the are switched when min/max is reached.

@ jesserockz Would you be able to help and state if there is an possible way to the following?

So, I am more or less new to the tuya component.

Nonetheless I followed the following to obtain my datapoints and device id.

Here is the output: (while I removed the parameters not used by this device)

The plug for PH or ORP of the device are switched when the “min” or “max” value is reached.
Currently I don’t see any possibility to switch the plug on my own.

Question:
Can someone help me to understand how I can modify the datapoints?
Especially these:

{
        "code": "ph_warn_max",
        "custom_name": "",
        "dp_id": 107,
        "time": 1691057134795,
        "value": 700
      },
      {
        "code": "ph_warn_min",
        "custom_name": "",
        "dp_id": 108,
        "time": 1691055107684,
        "value": 0
      },
      {
        "code": "orp_warn_max",
        "custom_name": "",
        "dp_id": 132,
        "time": 1691055108105,
        "value": 150
      },
      {
        "code": "orp_warn_min",
        "custom_name": "",
        "dp_id": 133,
        "time": 1691055108155,
        "value": -2000
      }

Appreciate every help on that.

Thanks

hate to say it Chris, but that Tuya website output doesn’t look like the ones I have used.

Did you perhaps use the “Get device specification…” menu option, or the “Get Device Specification Attribute” menu entry with capital “D” and capital “S” ?

Indeed it looks different to all I have seen for now, when getting details about Tuya devices from their api browser.

But yeah, I think the relays for the plugs are only indirectly controlled by “min” and “max” value for e.g. PH or ORP.

I opened the device, connected RX/TX of the CB3S chip to an ESP32 TX/RX.
So I am using that device only for measuring and doing the work in an own ESP.

Maybe useful for others:

I also soldered in an ESP 12-F. However, it doesn’t connect to the WiFi. But when I put the chip on my development board, everything works without any problems. Do you have to do more than swap the old chip for the new one?
