TP-Link Deco

---

🚀 Overview

This integration provides local polling control and diagnostics for TP-Link Deco systems within Home Assistant.

---

✨ Features

Diagnostics

• CPU usage (raw + smoothed)
• Memory usage (raw + smoothed)
• Backhaul and network diagnostics

CPU / Memory sensors

Two types of sensors are available:

• Raw → direct values from the Deco (real-time, can fluctuate)
• Smoothed → averaged values over time (stable, ideal for dashboards)

Use raw for:

• debugging
• real-time monitoring

Use smoothed for:

• dashboards
• automations
• trend analysis

TP-Link Deco

Functionality

This integration is a local polling integration that logs into the admin web UI for TP-Link Deco routers. Currently the only feature implemented is device trackers for active devices.

Device Trackers

Device trackers are added for both decos and clients. The device tracker state marks whether the device is connected to the deco. If a device is not present, the previous values for attributes are saved except for down_kilobytes_per_s and up_kilobytes_per_s.

Common Attributes

Attribute	Example Values (comma separated)
mac	1A-B2-C3-4D-56-EF
ip_address	192.168.0.100
device_type	client, deco
connection_type	wired, band5, band2_4

Client Attributes

Attribute	Example Values (comma separated)
interface	main, guest
down_kilobytes_per_s	10.25
up_kilobytes_per_s	11.75
deco_device	living_room
deco_mac	1A-B2-C3-4D-56-EF

Deco Attributes

Attribute	Example Values (comma separated)
hw_version	2.0
sw_version	1.5.1 Build 20210204 Rel. 50164
device_model	x60
internet_online	false, true
master	false, true
bssid_band2_4	A1:B2:C3:D4:E5:F6
bssid_band5	A1:B2:C3:D4:E5:F6
signal_band2_4	3
signal_band2_4	4
deco_device	living_room
deco_mac	1A-B2-C3-4D-56-EF

Note: deco_device and deco_mac will only be set for non-master decos.

Devices

A device is created for each deco. Each device contains the device_tracker entities for itself and any clients connected to it. Non-master deco devices will indicate that they are connected via the master deco device.

Services

Reboot Deco Service

Reboots the specified decos. Example yaml:

service: tplink_deco.reboot_deco
target:
  device_id:
    - ef41562be18e5e3057e232ffb26de9bb
    - d7f96b1f312d83f195b35ecdfbb3b02b

Installation

HACS

Manual

1. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
2. If you do not have a custom_components directory (folder) there, you need to create it.
3. In the custom_components directory (folder) create a new folder called tplink_deco.
4. Download all the files from the custom_components/tplink_deco/ directory (folder) in this repository.
5. Place the files you downloaded in the new directory (folder) you created.
6. Restart Home Assistant

{% endif %}

Configuration (Important! Please Read)

Config is done in the HA integrations UI.

Host

The IP address of the main deco which you visit in the browser to see the web admin page. Example: http://192.168.0.1. Some decos use https, so if you have trouble connection, try using https e.g. https://192.168.0.1.

Login Credentials

The login credentials MUST be the deco owner credentials and the username should be left as admin. Manager credentials will NOT work.

Also whenever the owner logs in, all other sessions for the owner will be logged out. So if you log in with the owner credentials in the mobile app, it will cause the integration to be logged out, sometimes resulting in 403 errors. Since the integration has built in retry on auth errors, the integration will re-login, but that will logout your mobile app login session.

Recommend that you create a separate manager account with full permissions to manage the router manually in the mobile app and use the owner credentials only for this integration. If you need to use the owner account to do some manual management, recommend disabling this integration temporarily. Steps to create a manager account:

1. Log out of the deco app
2. Sign up for a new account with a different email address
3. Log out of the deco app
4. Login to original admin account
5. Go to the "More" section and look for "Managers"
6. Add the email address of the new account
7. Log out of the app
8. Login using the new manager account you've just created

Timeout Secounds

How many seconds to wait until request times out. You can increase this if you get a lot of timeout errors from your router.

Note: The router also has its own timeout so increasing this may not help.

Timeout Error Retry Count

How many times to retry timeout errors for one request. You can increase this if you get a lot of timeout errors from your router.

Verify SSL Certificate

Turn off this config option if your browser gives you a warning that the SSL certificate is self-signed when you visit the router host IP in your browser.

Client Name Prefix

Prefix to prepend to client name. Example: Value of "Client" for "Laptop" client will result in "Client Laptop".

Client Name Postfix

Postfix to append to client name. Example: Value of "Client" for "Laptop" client will result in "Laptop Client".

Deco Name Prefix

Prefix to prepend to deco name. Example: Value of "Deco" for "Living Room" deco will result in "Deco Living Room".

Deco Name Postfix

Postfix to append to deco name. Example: Value of "Deco" for "Living Room" deco will result in "Living Room Deco".

Disable new entities

If you prefer new entities to be disabled by default:

1. In the Home Assistant (HA) UI go to "Configuration"
2. Click "Integrations"
3. Click the three dots in the bottom right corner fo the TP-Link Deco integration
4. Click "System options"
5. Disable "Enable newly added entities"

Notify on new entities

You can get notified by new entities by listening to the entity_registry_updated event. Here's an example automation:

- alias: Notify New Wifi Device
  mode: parallel
  max: 100
  trigger:
    - platform: event
      event_type: entity_registry_updated
      event_data:
        action: create
  variables:
    id: "{{ trigger.event.data.entity_id }}"
  condition:
    - condition: template
      value_template: "{{ id.split('.')[0] == 'device_tracker' }}"
    - condition: template
      value_template: "{{ id in integration_entities('tplink_deco') }}"
  action:
    - alias: Wait a little while to make sure the entity has updated with new state
      wait_template: "{{ states(id) not in ['unknown', 'unavailable'] }}"
      timeout:
        minutes: 1
    - service: notify.mobile_app_phone
      data:
        title: "{{ state_attr(id, 'friendly_name') or id }} connected to WiFi"
        message: >-
          {{ id }} connected to
          {{ state_attr(id, 'interface') }}
          {{
            state_attr(id, 'connection_type')
              | regex_replace('band', '')
              | regex_replace('_', '.')
              | regex_replace('$', 'G')
          }}
          through
          {{ state_attr(id, 'deco_device') }}
        data:
          group: wifi-new-device
          clickAction: "entityId:{{ id }}"

Resulting notification looks like:

title: "Amos Phone connected to WiFi"
message: "device_tracker.amos_phone_wifi connected to main 5G through Guest Room"

Known Issues

Timeout Error

Some routers give a lot of timeout errors like Timeout fetching tplink_deco, which cause the devices to be unavailable. This is a problem with the router. Potential mitigations:

• Rebooting the router
• Increasing timeout seconds in integration config
• Increasing timeout error retry count in integration config

Extra Devices

You may see extra devices show up under the Tp-Link deco integration as per #73. This is expected because the entities use macs for their unique ID. If there is another integration that exposes the same device using their mac, Home Assistant will combine the info from devices that have the same unique ID. This is working as intended since they represent the same device.
