Frans, I also use serial communication and have done quite some work in figuring out all the status, beeps, how to send commands and stuff which might be similar to what youāre building. Have a look here: https://github.com/fwpt/HASS-Jablotron80-T
Although Iām using the JA-80T Serial USB interface, the output will be identical to what youāre capturing with your serial connection so some of my code might be helpful to you.

I tried to determine the algorithm for the check digit, but failed to find a match. I tried sum, weighted sum, xor and then some but none seem to fit. Maybe it is not even a check digit. Most of the peripherals are battery powered and do not have the processing power to use sophisticated crcās.
@fwpt
I already found your solution. I simply emulate a keypad so I donāt need to decode all messages. My main problem was flow control on the RS485 bus. Even with my diy device as the only device on the bus, communication was initially hit and miss. Now with waiting for the 0xA0 response for max 1 second and resending the key code if no acknowledgement received within that time, communication is 100% OK. The device is essentially the Jablotron MQTT bridge you mentioned in the description of your solution.
I have a Jablotron JA-106-3G and I configured it in home assistant (installed on raspberry pi 4) using the USB cable.
How can I extent it to MQTT communication without using any wiring?
For some reasons code_arm_required: true the configuration is not respected. Furthermore I canāt use with Alexa because I suspect that the arm required true property is not supported.
Is anyone able to arm/disarm Jablotron80 through Alexa? Jablotron is added as device there but when I select it as device in a routine it says - the device is currently not supported.
Hello, I have JA-107KR. All of you connect HA directly to alarm (USB)? I want to use JA-121T, witch give me less informations but I think that this is more safe.
Will this integration work with JA-121T? If no, can you point me where to start?
Thanks
NB: In the end, I opted for USB + the four input/four output module. An Arduino with Firmata now communicates with this I/O module to trigger an alarm from Home Assistant.
Hi @mazzy
Good going. I have a 80 series too and wanted to know whether you are able to get status of all sensors (wired and wireless) while the alarm is not armed?
Would really appreciate more details on your install. How connected what are you able to Automate etcā¦
