node-red-contrib-tapo-p125m

Node-RED nodes for reliable local LAN control of the TP-Link Tapo P125M smart plug using tp-link-tapo-connect.

Why

Some existing Tapo Node-RED nodes can read status but fail to toggle the P125M reliably.
This module provides explicit ON, OFF, and STATUS nodes with a shared configuration node.

Install

From the Node-RED Palette Manager, search for:

node-red-contrib-tapo-p125m

Or install manually:

cd ~/.node-red
npm install node-red-contrib-tapo-p125m

Restart Node-RED after installation.

Nodes

Config node: tapo-device

Stores:

• Device IP address
• Credentials (stored securely in Node-RED credential storage)
  OR credentials via environment variables

Action nodes (category: Tapo P125M)

• P125M on
• P125M off
• P125M status

All action nodes reference a tapo-device configuration node.

Credentials

Option A: Node-RED credential storage (recommended)

Enter Email/Password in the tapo-device config node.
Credentials are stored in flows_cred.json and are not included in exported flows.

Recommended setting in ~/.node-red/settings.js:

credentialSecret: "your-long-random-string"

Option B: Environment variables

Enable Use env vars in the tapo-device config node and define:

export TAPO_EMAIL="[email protected]"
export TAPO_PASSWORD="yourpassword"

Example output

Success:

{
  "ok": true,
  "cmd": "on",
  "ip": "192.168.1.11",
  "device_on": true,
  "model": "P125M"
}

Error:

{
  "ok": false,
  "cmd": "off",
  "error": "Missing credentials in tapo-device (or env vars)."
}

Example flow
