Tuya Smart Valve Integration - Home Assistant for Organic Farming

Job Description: Tuya Smart Valve Full Integration Into Home Assistant (Mavronero Farm – mavronero.cy)

At Mavronero Farm (mavronero.cy), we use Tuya smart irrigation valves equipped with a water meter and a soil sensor. These devices are already connected to Home Assistant, but we need a specialist to fully integrate them using all available Tuya DP (datapoint) codes for complete control, monitoring, and automation.

We are looking for an experienced Home Assistant / Tuya developer to complete the integration.

What we need:

Clean Integration

Ensure the valves are connected only via Xtend Tuya (local)

Remove or disable Tuya Cloud duplicates

Enable “Expose all DP codes” so all datapoints become visible in Home Assistant

Full DP Mapping
Create correct Home Assistant entities for all relevant functions:

Valve on/off

Irrigation countdown time

Soil moisture

Soil temperature

Soil sensor battery

Valve battery and charging state (bit decoding)

Water flow / capacity

Irrigation cycle count

Fault states such as flow meter error, no water, low battery, sensor offline

Start and end timestamps

Automation DP codes

Any raw DP commands needed for advanced control

Usability Improvements

Convert raw DP values into readable template sensors

Create a script: “Run irrigation for X minutes”

Optional: create a dashboard card showing soil moisture, soil temperature, battery levels, faults, water usage, and valve controls

Optional Automation

Automatic irrigation based on soil moisture thresholds

Requirements:

Strong experience with Home Assistant

Knowledge of Tuya Local or Xtend Tuya

Experience decoding and mapping DP codes

Ability to create YAML template sensors, scripts, and automations

Access:
Remote access can be provided through AnyDesk or a guided session.

Goal:
A fully working and stable integration where all DP codes from the Tuya valves and soil sensors at Mavronero Farm (mavronero.cy) are available, decoded, and usable in Home Assistant, enabling smart and reliable irrigation control.
