Tapo P110M Energy Monitoring: Apple Home, Matter and Home Assistant in Australia

The short answer: the Australian Tapo P110M can report energy over Matter with suitable firmware and a supported platform. However, working on/off control does not prove energy support. TP-Link's published feature table lists energy monitoring in Tapo and SmartThings, but not Apple Home, Google Home or Alexa. Its Australian firmware notes also identify Home Assistant support. Do not buy a Thread border router to fix missing readings: this is a Wi-Fi plug.
Documentation review, not a product test. Sources were checked on 23 September 2026. This guide covers Tapo P110M(AU), hardware V1. We have not measured its accuracy, tested internet-outage behaviour or confirmed every app/firmware combination. P110, P110M and similarly named overseas products are not interchangeable evidence.
What changed, and which firmware matters?
The Australian V1 release notes list 1.3.2 Build 250526, published 30 July 2025, as adding Matter 1.3 power and energy reporting. They explicitly warn that apps differ in support and name SmartThings and Home Assistant as functional platforms.
The same page now lists 1.4.3 Build 260526, published 6 July 2026, with stability and security improvements. Use the update offered for your actual unit through TP-Link's supported process; do not install another country's firmware or treat a forum's version number as the Australian minimum. A newer release also does not prove that a particular historical fault was fixed unless its notes or testing establish that.
Where should the readings appear?

| Where you want data | What the documentation establishes | Buying implication |
|---|---|---|
| Tapo app | The AU product page describes energy tracking and electricity-rate estimates. | Try your existing plug and app first; a new Matter hub is not needed just for Tapo monitoring. |
| Apple Home, Google Home or Alexa | TP-Link's 27 January 2026 feature table marks energy monitoring unsupported. | Do not buy P110M specifically for energy graphs in these apps without newer explicit confirmation. |
| SmartThings via Matter | TP-Link lists support with setup qualifications. | Check its energy setup instructions and your controller before purchasing anything. |
| Home Assistant via Matter | AU firmware notes identify energy support with compatible software. | Update the existing setup and inspect entities before replacing hardware. |
| Home Assistant TP-Link integration | P110M is listed; energy-capable devices can expose consumption sensors. | This is an alternative integration path, not another plug purchase. |
The TP-Link ecosystem feature table is dated documentation, not a live test of today's apps. Its own warning says features can change. Use it to avoid an unsupported buying assumption, not to claim an ecosystem can never add the feature.
If on/off works but energy does not
- Identify the connection. Is this a Matter device in your app, a TP-Link integration, or a vendor-cloud connection? A model appearing in an app does not identify the route.
- Record the label and versions. Note P110M(AU), hardware version, installed firmware and controller/app version. Compare against the regional release notes, then update using supported tools.
- Check Tapo separately. If it shows readings while another app does not, investigate the integration and feature support before concluding the meter is broken.
- Inspect Home Assistant's device entities. Check whether power or energy sensors are available or disabled. Preserve existing automations and history before removing or re-pairing a device.
- Separate a missing sensor from a missing dashboard entry. A sensor can exist without being eligible for the particular Energy dashboard field.
A Home Assistant discussion contains both reports of successful energy monitoring and questions about readings appearing only as diagnostic data. It also contains an older report of readings disappearing after prolonged internet blocking. These are user reports with different setups, not proof of the current Australian firmware's behaviour. They are a reason to check your required function rather than assuming Matter makes every feature internet-independent.
Home Assistant: energy is not the same as power
Watts describe the present rate of use; kilowatt-hours describe accumulated energy. In the current Home Assistant Energy FAQ, an energy sensor needs the appropriate energy device class, a total or total-increasing state class, supported units and working statistics. Inspect those attributes and statistics errors if it is missing from the consumption selector. Do not simply rename a watts sensor to kWh.
If you choose the TP-Link Smart Home integration instead, read its prerequisites: Tapo devices require authentication for local access, and some firmware requires Third-Party Compatibility to be enabled. Keep credentials inside your own trusted installation. If both integrations expose the same plug, select one consumption source for it rather than counting the same appliance twice.
When no extra hardware is the right answer
For Tapo-only metering, use the plug's existing Wi-Fi connection and app. For third-party Matter control, check your controller requirements; a Thread radio cannot add energy support to an app. TP-Link's setup guide describes direct Matter setup and multi-admin sharing, while recommending Tapo-first setup for full features.
Before buying, confirm the Australian plug variant, your required app, firmware support and appliance suitability. Metering does not guarantee savings. If you only need a whole-house usage overview, check information already available from your electricity retailer before buying multiple appliance meters.
Electrical safety still comes first. Follow both appliance and plug instructions, including load type and startup current—not just a wattage limit. Do not use this guide to remotely start a portable heater or other heat-producing appliance. TP-Link's load and heat guidance says to stop using a plug that is too hot to touch or smells burnt.
