Not ST related, but this group seems to know their stuff when it comes to WiFi. last year we moved into a house that had what I thought were standard smoke detectors, but they ended up being smoke detectors as part of the AT&T digital life system that was offered years ago. We don’t subscribe, and those are not hooked up to our Wi-Fi, but I know they are Wi-Fi compatible. Let’s assume that they are looking for a standard Wi-Fi system and not the digital life hub (since I don’t know),  could they be hogging up my Wi-Fi bandwidth (or even weakening my signal around the house) by trying to connect even though they don’t have the password, or do they have no affect?
