I’ve got the app set up, if I can help somehow meddling with tcpdump and network tracing just ask and I’ll try.
OK, let’s start 
I created a dedicated thread under “Share your projects!” → “Custom Integrations”
Custom Integration: Tecnoalarm Italian anti-theft system to track it better
The TecnoAlarm Alexa skill stopped working on October 31st.
As of today, it still doesn’t work.
The support service, which I urge you to contact, has not yet replyed to me.
Hey @Mirmanero apologies but I’ve not logged in the forum in a long time.
I usually look at HomeAssistant either during Christmas holidays or summer holidays where I have more free time 
I’m glad to hear that you were able to find out more. I’ve joined the Telegram group to discuss there 
Merry Xmas everyone 
il prodotto più adatto è HSYCO Gateway Tecnoalarm / MQTT Client:
SKU: GGCMX41-MQCTAL
In questo caso, HSYCO dovrebbe comportarsi come client MQTT verso Home Assistant. Non entro nei dettagli dell’integrazione, perché il gateway viene fornito già configurato per la lettura degli stati dalla centrale Tecnoalarm, ma non per il dialogo diretto con Home Assistant.
La logica MQTT lato HSYCO va quindi sviluppata tramite le sue funzionalità di scripting.
In alternativa, esiste una soluzione più semplice che non richiede sviluppo di integrazione: HSYCO Gateway Tecnoalarm / Modbus Server.
SKU: GGCMX41-MOSTAL
In questa configurazione, HSYCO legge gli stati dalla centrale Tecnoalarm e li espone tramite una tabella Modbus Server . Un client Modbus TCP/IP (Home Assistant, lo supporta nativamente) può quindi leggere direttamente i dati.
Qui trova i dettagli tecnici:
Please write in english, since this in english forum.
Second: if i understood what you’re saying this modbus adapter reads panel status from tecnoalarm server, which is useless. It’s down too many times, so i gave up on it a while ago. I use old tecnoalarm app which connects to panel directly, not via tecnoalarm server. Last thing i want is something which will be unavailable 50% of the time…
No. This DIN module directly reads the data in real time from the home tecnoalarm control unit. Does not make api calls to the cloud. The data is read instantly from the tecnoalarm bus and converted for ha
Ok, that’s great, but… 700€+ …? Is that really the price? You’re joking, right?
I'm not sure to understand this message. Can you confirm that you can't use a Konnected integration with a TP8-28? I thought it worked with every type of alarm
That's great!
A question: can you include TP10-42? It's pretty commonly used panel and it would complete TP series still produced.
Can we expect any sort of beta test?
Yes, I'm finding a beta tester for TP models. We can try.
Please ask you installer to set a passphrase for e.g. 1111111111111111 and share the port.
Please send me a PM for the next step, after installer set these parameter.
Bye

I just got an answer from my dealer: TP10-42 doesn't support tecno out protocol, only tp8-88, tp20-440 and ev series, as on your list. And, it's optional: you have to get an additional licence for panel to be able to activate it.
