Adding Aico Smoke Alarms to Home Assistant, without using their cloud!

I found a way to connect my Aico smoke alarms to Home Assistant without using their cloud.

I came across this Panel Interface Module that using the works with the Aico SmartLink and RadioLink system.

Ei413 RadioLINK Panel Interface Module | Aico

I have two smoke alarms that are wired together and one heat alarm (in my kitchen) connected to the smoke alarms using SmartLink modules.

The Interface Panel uses relays to signal status and even has the ability to trigger the smoke alarms! As it’s powered with DC and uses relays for signalling, I added a Shelly i4DC to detect the status changes. I then added a Shelly 1 (switched to DC) to give me a way to trigger the alarm. I powered it all with a basic a 12V LED Driver.

I was able to add the connect the older RadioLink module to the newer SmartLink without any issues.

It all looked like this:

I can now respond to fire alarms and faults, and even sound the alarms, without any cloud. Perfect local control!

I’m writing up a more detailed blog post, but I made a video of how I figured this all out (I look pretty smug with it all works)

Great project!

I did the same last year using the Ei413 module I picked up for a bargain price.

Similar type of idea but I used an ESP32 to do the I/O which has been rock solid.
Using one of the Blueprints available I also added a number of Xiaomi bluetooth temperature modules around the house that will trigger the smoke alarms if they exceed a threshold temperature.
Quite simple and just gives an extra layer of peace of mind.
When they trigger I use an automation to whattsapp and HA send alert to the family mobiles.

Definately a good solution to add that extra montoring function. I wanted something that would not interfere with the Aico Smoke Alarms.

Nice work.
