Product review

The dual functionality of being both a smoke detector and carbon monoxide is useful, particularly for those with gas heaters etc
Some first hand experience from one of our members has found the WiFi connection via iOS has been flakey, losing connection several days after set up.

Still investigating as to the likely cause. e.g.
is there a problem with network which has both 2.4 GHz and 5 GHz channels?;
MacOS Ventura has been having some issues with network connections via home modem and so this may be contributory factor?
