A suite of wireless fire detection would be awesome, but to cover a whole house this needs capability for smoke (with the option to toggle optical / heat) and co2, also have a relay module so the fire detection system can connect to a security alarm system for 3rd party monitoring. Aico makes a decent suite but it’s $120 for a single unit so $600+ to cover a house, and surely this could all be integrated into one unit with option to switch off the tech which is not needed (eg optical near a bathroom or garage).
