smarterpool-auth

Read-only CLI helper to recover Tuya device information from a Smarter Pool account, mainly for configuring Home Assistant local Tuya integrations.

The primary use case is retrieving the Tuya deviceId, localKey, DPS values, and schema for Smarter Pool / Garden PAC InverTech pool heat pumps without re-pairing the device.

Who Is This For?

Use this tool if your pool heat pump is controlled by the Smarter Pool Android app and you want to integrate it locally with Home Assistant, tuya-local, localtuya, or TinyTuya.

It is especially useful when the device is paired with the Smarter Pool OEM app and is not visible from Tuya Smart / Smart Life without re-pairing. Re-pairing can change the Tuya localKey and may risk losing app-specific functionality, so this CLI reads the needed local credentials from the existing Smarter Pool account instead.

Search terms this project is meant to cover: Smarter Pool Home Assistant, Smarter Pool Tuya localKey, Garden PAC Tuya, Garden PAC InverTech Home Assistant, pool heat pump local Tuya.

Status

Experimental. It was built from reverse engineering of the Smarter Pool Android app and the Tuya OEM mobile API. The tool only performs login and read-only device information requests.

The Smarter Pool Android app credentials for version 1.0.3 international are bundled as the default app profile, so normal users should only need their Smarter Pool account credentials.

Tested With

• Smarter Pool Android app 1.0.3 international
• Garden PAC InverTech GHD-150-0356 swimming pool heat pump
• Tuya product ID koAASpds906awojG
• Home Assistant with tuya-local

Usage

npx smarterpool-auth [email protected] 'password'

For local use, prefer a .env file:

cp examples/smarterpool.env.example .env
$EDITOR .env
npx smarterpool-auth --env .env

By default the output redacts secrets, including localKey, session tokens, app secrets, and passwords. To print values needed by Home Assistant:

npx smarterpool-auth --env .env --show-secrets

Use --output to write the report to a file:

npx smarterpool-auth --env .env --show-secrets --output smarterpool-device.local.json

Files ending in .local.json are ignored by Git in this repository.

Required Configuration

Account credentials:

• SMARTERPOOL_LOGIN: Smarter Pool email or phone number.
• SMARTERPOOL_PASSWORD: Smarter Pool password.
• SMARTERPOOL_COUNTRY_CODE: phone country code, defaults to 33.
• SMARTERPOOL_DEVICE_ID: optional Tuya device id. If omitted, the CLI tries discovery. If exactly one device is discovered, it is inspected automatically.

Optional Tuya OEM app credential overrides:

• SMARTERPOOL_APP_KEY
• SMARTERPOOL_APP_SECRET
• SMARTERPOOL_SECRET2
• SMARTERPOOL_CERT_SIGN
• SMARTERPOOL_REGION
• SMARTERPOOL_TTID

The bundled default profile comes from the public Smarter Pool Android app 1.0.3 international. These values are not user account credentials, but they may stop working if Smarter Pool rotates app credentials in a future release. Use the override variables if you need to test another APK version.

Home Assistant

The output is useful for local integrations that need a Tuya deviceId and localKey:

• tuya-local
• localtuya
• TinyTuya

For tuya-local, configure the device with:

• Host: the local IP address of the pool heat pump.
• Device ID: device.deviceId from smarterpool-auth --show-secrets.
• Local key: device.localKey from smarterpool-auth --show-secrets.
• Protocol version: device.protocolVersion, or auto if the integration supports it.

For localtuya, use the same deviceId, localKey, IP address, protocol version and DPS values. The device.dps and device.schema fields can help identify which DPS should be mapped to Home Assistant entities.

Example command for local integration setup:

npx smarterpool-auth --env .env --show-secrets --output smarterpool-device.local.json

Do not paste smarterpool-device.local.json into public issues, because it contains the Tuya localKey.

• Treat Tuya localKey like a password for local network control of the device.
• Rotate the device key by re-pairing the device if it was exposed.
