Main use I have for Numerous is it has a free app capable of receiving push notifications based on event boundaries that you set. It can also show data in real time via iOS icon badges. I think it will work excellently if I can get my Core talking to it.
One of my projects is monitoring a sump pump alarm circuit and having any “alert” events sent to my phone is going to be a key part of it. This is actually the real-world issue that led me to discover Spark in the first place. Now I have many more ideas where it could be useful!
Not married to Numerous–it’s just the best candidate I found so far. Just today I discovered yet another data logging source at data.sparkfun.com but that doesn’t seem like it will get me further than Ubidots. I really need either push notification or SMS support, but would prefer PN as it involve carriers at all and would thus work on iPads or situations without carrier service (like overseas travel).
