I don’t want this to sound like an accusation or anything, but is Cayenne still in the early stages or something? Maybe I am just not the target market, but it seems very simple-minded to me, even with the REST API. I’m sure those simple things are useful for a lot of things, but they are still pretty limited.
For example, I can set a threshold alert for a sensor. Yay. But I want to send an alert/notification only after my data is above a certain value for at least N minutes. I want to send another alert/notification when it gets back down below some threshold … after having been above the threshold for a while.
For example, if my temperature sensor goes below 32F for more than 15 minutes and the trend has been generally downward, then send me an alert. On the other hand, if I am 10 minutes into my long drive to a remote site and the temperature goes back up above 34F, send me another alert so I can go back home and have some eggnog.
Maybe I’m just not good enough at finding out about Cayenne features, but the only way I can figure out to do those things is to keep track of it on my device and then send some kind of fake sensor data to Cayenne when I want things to happen. If I have to do that, all I’m getting from Cayenne is an inconvenient SMS or email notification service. There are about a zillion ways to do that these days.
Again, I’m not accusing Cayenne of being useless or saying that you should cater to my special needs. I’m really just asking if I’m in the wrong place for what I am looking for.
