Thanks, but only work if the alarm is armed?

this is correct. in other words when alarm is disarmed, for instance door contact are not reported to SIA. I never checked, maybe it would be reported if “Always active” at sensor level is on, but then the battery would be drained more rapidly.

Having a strange issue with the SIA device. Earlier the alarm was triggered, ever since HA has been flip flopping between triggered and unavailable despite being cancelled by Ajax hours ago, anyone else experienced this?

Is anyone having contact with Ajax team on API registration? I would love to receive data from detectors like temperature and status without the SIA protocol demanding it to be armed.

I do have some reseller connection but before I ask them maybe there some roadmap by now.

Cant we listen and make data request via uartbridge?

(didnt read the complete manual)

Old development:

I’m probably one of the few not having an Ajax system… I’m using Aritech ATS and I don’t receive a Heartbeat. I’m listening to port 12300 and I have set my PAC to communicate to 192.168.1.140.

I have also installed the utcar docker at my Synology NAS running at 192.168.1.100, but also no Heartbeat detecting.

Am I doing fundamentally wrong? It has something to do with my alarm system I guess…

Hi folks!

I apologize for my long absece, i’m come back to working at Ajax project, i starded to create a library on GitHub, here it’s the link:

I hope i can find someone that helps me to build the library…

Unfortunately I’m of no help as far as development is concerned, however I’m more that willing to test anything you’d like.

I’ll have a look and start contributing code when I have a moment

I connected the Ajax system through the usual SIA integration. So I get events when I arm or disarm the system, or when there is an alarm.

Enabling or disabling the Ajax system is not possible through SIA, and an API connection seems to be unavailable. So to solve this, I simply took an Ajax remote and soldered it to an ESP8266 device.(In my case a Wemos D1 mini). The Wemos also provides 3.3 volt to the remote, so I can leave out the battery.

In ESP home I configured the ESP device to pull down ports D5 and D6 for half a second if they are activated. These outputs are soldered to the buttons of the remote, now I can switch on and off the alarm system with HomeAssistant.

from two days, ajax central unit made update and even haos. Now i have problem and SIA is not connectd. Similar problem to you ?

Yes I had that as well. Can’t say whether it is HAOS or Ajax firmware that has been updated at the same time. In order to try to solve it, in Ajax app I toggled several times Connect on demand. It seems that it is stable now.

Yes. I try to change settings in Ajax app, and sia connect well, but after one day, it is disconnected.
I think about my recent installation of Pihole as DNS filter, but sia and Ajax , transfer under my network.
Ind like try to disable it

I use HA companion app to forward Ajax notifications and sync Ajax status with status in HA.

Here is my example

Hello,
my ajax did firmware upgrade few weeks ago. But with the upgrade of HAOS it stopped to work… any idea? is that a hass bug in the sia plugin?

Thanks!

please have a look at my post a little above your post

@kolia okay, thanks i did that and it works… did that via mobile ajax app.

still no idea why… that fixed issue?:slight_smile:

thanks

mee too. If you enter in ajax setup up, and disable and able, some SIA function, it work again with HA, but for one day, and again disconnection…i don’t know why
