Ajax systems integration to complement home security


I’m using Ajax systems for home security. Ajax is very plug and play and completely wireless. An integration with homey could complement Ajax enormously.

Some examples:

  • when a door is open spin the led ring
  • alarm triggered: turn on all the lights
  • Ajax panic button: open all doors, turn on all lights
  • fire detected: open all doors, turn on all lights


Anyone else using Ajax systems?
Anyone interested to write an integration?



Looks like a nice system, but the API seems to only be available to “large security and service companies”.

Dont know, Ajax is not aloud in my house :stuck_out_tongue_winking_eye:

But on-topic, there is a general topic on the forum where you can do your requests. Just to keep it central

What a company : “How many Ajax systems does the company manage or plan to manage? (min 1000/month) *”

Yes, seems so.

Please help and vote for:
Public API: https://ajax.systems/wp-admin/admin-ajax.php?action=process_simple_like&post_id=6147&nonce=66675f3a9d

Homey integration: https://ajax.systems/wp-admin/admin-ajax.php?action=process_simple_like&post_id=2424&nonce=66675f3a9d

not sure if above links will work like this… can’t find a direct URL :s

I have the Ajax alarm system as well and following the progress regarding usable API’s.

The above API is indeed Enterprise only.

I did find this library for the Ajax API in the past:

Maybe that would be helpfull. I am for sure they are going to focus on domotica at some point. I think they already presented new home devices.Look at these feature requests and the number of votes:

I have received some Info from Ajax support.
Public Api not yet on the roadmap, but IFTTT support later this year.

I am following Ajax Systems approach on API / domotica support closely. I had selected the Ajax Systems alarm as the alarm I want to install in my new house. But the lack of domotica integration / API support has started some doubts. The alarm in my current house is Woonveilig/Egardia and I must say that the Homey integration - however simple - is a very nice addition.
I have mailed Ajax about their plans. I don’t think one individual will make a difference in their approach but who knows, if they hear it from many people it might.

@Jo_San did you see the following: https://ajax.systems/features/

@Earl_Grey yes I did, also voted for Homey and Zwave support. Not sure when an idea will get on the actual roadmap though. Some of them are on the idea list for quite some time now.

Well, that’s your answer right here :slight_smile:

IFTTT integration is coming Q3/Q4 2019, so via this way we can link it to homey

I hope Homey will add an app for the ajax system which is very evoluting


The problem is that Ajax does not (yet) provide an API to connect to… without an API it is not possible to build a stable app.
I am also eagerly waiting.


Great news! Some people on Home Assistant made it possible to read the states from the AJAX hub. It is done through the SIA protocol.

The thread: https://community.home-assistant.io/t/ajax-alarm-system/62853/44

I will try this on my HA instance and then push or pull the states in Homey.

That sounds great. As I read it, the SIA protocol is something generic. Maybe someone already experiented with that in relation with Homey?

Good news I hope someone will help us

I created a very basic link between Ajax and Homey by using an Ajax Smartplug and an Innr smartplug. The Ajax smart plug is automatically turned on when the alarm is armed and turned of when disarmed. I placed the Ajax plug in an Innr SP120 plug which measures the power consumed. When the Ajax plug is turned on, the Innr plug measures power and lets Homey know that the alarm is on. Vice versa for off.
That way I can turn on my camera’s when the alarm is armed.

For me it is sufficient for now. I hope to be able to use sensor data in the future.
