cooker with Recalart Economic 3000 controller - alarm transmission via control panel

Hello,
i have the above-mentioned controller in my cooker and I would like to connect it to the control panel in order to receive information that the alarm on the cooker has been activated, I have not found any interface in the controller but there is a red diode which starts to light in an alarm situation, so the question is how to connect it to the control panel (Satel Integra)?

What voltage is applied to this diode?

From what I measured while this diode was on, it was 1.7 V

A little low, look for where there is any higher voltage from 5 volts upwards in the driver when the diode is lit.

It took me some time (I had to educate myself "a bit" in electronics) but in the end I think I found a solution, for now it's a test, but it works, it remains to try it on the cooker (which I intend to do soon)

i've duplicated the signal by connecting an optocoupler in parallel to the alarm diode, which controls a second independent circuit, from which I read the signal on the Arduino, and this via serial to the computer, where a Python script runs, which waits for information about the alarm (lighting of the diode on the cooker) and sends me an sms in case of failure

Added after 3 [minutes]:

now i've had another look at the first post, of course the same can be hooked up to the mentioned control panel instead of the arduino

Has anyone connected the Integre to a Recalart Economic 3000 controller?
Greg161 and how does it work?
