Integration of the Sonoff SV with the Satel CA6: Concept, security and relay minimisation

Welcome colleagues

I have this thought on the integration of sonoff with sateel ca6 and since I am not an electronics engineer I would like to know if I am thinking correctly and if I have forgotten anything in this solution

I have uploaded supli software to the sonoff sv with thermometer and open sensor and isolated the relay output. I'd like to get an alarm notification so I figured I'd power the sonoff from the control panel and connect the opening sensor input via a low current OC type output on the control panel and program it as an alarm. The sonoff output will be connected to the control panel input and programmed as an arming/disarming mode. What do you think of this solution? Do you see any weaknesses in the protection against some kind of overvoltage? I know I could do it with external relays, but I would like to keep the number of them to a minimum.
Regards

Aside from the obvious disadvantage of (in my opinion) exposing your system to the network, there is one more,
that you don't have feedback on the status of the control panel when it is remotely armed/disarmed. In my opinion, a 'bowel'.

Do you only have one alarm input?

Yes, there is only one in the sonoff, besides, it is an alarm on the plot and I care most about the remote deletion of the alarm after checking on the cameras that it is only a mouse.....a not to digress at night 120 km so that the neighbors can send.

It makes all the difference that the system status indicator could be an LED in the camera range controlled from an output like an arming indicator.

Yes there is only one thing in sonoff,

So I didn't really understand how you plan to connect it?

I thought you were referring to the input on the control panel and not on the Sonoff

Instead of the Sonoff, you can use, for example, the Wemos D1 mini board where more GPIOs are available for use. Instead of relays, optoisolators can be used. Please note that no more than 3.6V can be applied directly to the GPIO esp82xx

I have ordered and will be testing .
