I'm looking for ways to improve the speed of my OP2. Maybe it's just getting old.. lol. Anyway, looking at my zwave lighting, but also wonder if there are types of code that could potentially cause delays in my setup. For example, when I open my garage door (into the house) or my garage door (leading to our backyard), the "not ready" of those zones issues a command to turn on the lights in the garage for a certain amount of time. In general, it works fine. However, sometimes it delays by 10 seconds and other times I have seen delays like at 30 seconds. 95% of the time, it is within a couple of seconds. I figure, something must be causing these differences (besides my zwave setup) and wonder whether some of my code that checks things every hour, etc. is doing this. Not sure, but wondered whether there are some "don't dos" with HAI code that I can look for. Thanks. SJ
