Hi. I’m using Honeywell/Resideo Evohome Security.  
Unfortunately there is no app available in Homey yet.  
Would anyone know if it is possible to copy the signal from a TCC800MS Key Fob?  
If so, I could use this signal to switch the alarm on and off using Homey.

And probably it will have an Rolling code so changing every time for security reasons.  
If not and if it was that easy to copy I would have replaced it with another Alarm…
