@TEWphotography @txsarge , I had to chime in on this discussion because I’m one of those 200-300 device people (and growing). I have a wide variety of devices from a wide variety of manufactures, and they’re WiFi, zigbee, and zwave using my own custom device handlers in many cases. I can honestly say I spend more time in this community reading and contributing, and developing code (I say that loosely btw) than fixing problems.
I do not use ST for security, but for HA it’s doing a ton of stuff around our home. My family and I use ST every day (with Alexa in the loop), and we have some reliance on it for certain lighting requirements, leaks, and thermostat management. I don’t rely on phone presence for anything.
While I’ve had my fair share of issues, a good portion can directly be related to things I did (to break or fix for that matter). The rest are caused by ST, but nothing like what I see others go through. I’ve been using sunrise/sunset triggers for so long I can’t remember (2+ years), Smart Lighting for almost everything, and now more and more SHM rules.
I check my ST ecosystem daily for anything odd, but I can honestly say that I’m doing much better now than any other time I can remember, and I’ve been with ST since December 2013.
What @JDRoberts stated above is so important, as well as hub placement, signal interference, zwave/zigbee repeaters, mesh health, etc. I literally have my hub hanging behind a dresser between a mirror and wall completely out of view (wife requirement), and it’s on the opposite side of the house from any other network device.
I’m not saying ST doesn’t have their fair share of problems, far from it. I do strongly believe they have gotten better, but they still have a lot to do.
