Installing & Integrating Clipsal Wiser Smoke Alarms In To Home Assistant & Amazon Alexa

Complete – 2nd Week Of November 2025


Recently I installed a few solar batteries and as a result of doing this I needed to install an additional smoke alarm. Given the need to add a new alarm and my drive for consistency throughout my house I was on the hunt for 5 smoke alarms that can integrate in to my smart home and meet Australian Standards. I am after protocol over proprietary standard, such as Tasmota (MQTT), Zigbee, Serial, REST.

After assessing the market I landed on square Clipsal Wiser Smoke Alarms. I did have hestitations as there is a lot of mentions around the use of a Clipsal Wiser Hub, which after resarching is just Zigbee.

No one could easily confirm these would work with Home Assistant, but again these are protocol so they should work, right?

So in this post I will show you how do multuple things

1. How to link up multiple Clipsal Wiser Smoke alarms together, with one being a master, without a Clipsal Wiser Hub
2. Integrate each Clipsal Wiser Smoke Alarm in to HomeAssistant via ZHA (Zigbee Home Automation)
3. Create automations based on Clipsal Wiser Smoke Alarm Events, specially
   • Injecting Speech in to Amazon Alexa devices via the Amazon Media Player Integration
   • Flashing Lights in Bedroom and Main Living Room areas.
   • 
     

Installation
For the purpose of this of this post I am going to assume you have your Clipsal Wiser smoke alarms installed and wired up. Below are a few pictures of my square 240V units, but this post is applicable for both square and round units, 240v and battery, and it goes without saying installation without 240v is considerably easier.

I have attached manuals below for both square and round 240V units. The button locations for pairing may be slightly different but the approach and pattern for pairing to Zigbee Home Automation in Home Assistant is the same.

Pairing Units Together Without A Clipsal Wiser Hub
These smoke alarms can run as individual units or can be linked together so that when one alarm is activated all alarm, and this can be done without the use of a Wiser Hub.

Integration With Zigbee Home Automation

But modern devices do more than just turn on and off, they contain a plethora of functionality, and hence the need of remotes. Yes applications on phone often exist, but they are cumbersome for other reasons.

So how can you keep all that functionality, but integrate these modern devices into your house so they just blend in

I recently purchased 4 x Ventair SkyFan’s for my house with TUYA modules. I initially explored using Amazon Alexa (one present in every bedroom) and Home Assistant, both work to varying degrees, but they are clumsy in many ways. The time it take to issue an utterance to Alexa (Alexa, Set Parents Fan to Speed 1), or to touch an Home Assistant Lovelace dashboard is dwarfed by the simplicity and speed of a button press, especially as you enter or exit a room.

So in this post, l am going to walk you can add an additional control plane to your remote controlled devices. This additional control plane will be in the form of Clipsal push button switches that match other switches in my house.

And as usual lets start with an end-2-end demo.
