I've never seen any issues arise from overloading the Tesla APIs in evMote. I manage the traffic pretty well. That's another way of saying that every issue with evMote so far has been 100% because I screwed something up
There is a lot of instability with the Tesla API though. It doesn't feel like it's a priority for them. Here's a dashboard I use to keep an eye on evMote:
At the top right, you can see the constant errors that come back from the Tesla API. I usually just auto-retry those requests and they work. Not ideal.
Also in the middle right, you can see errors I get back from the GPS tracking API. I usually just drop that particular GPS coordinate. You wouldn't notice because the tracks come in pretty quickly and one point isn't noticeable.
Also, note the dip in the bottom right graph. That's the graph for number of trips that were stopped. You can see that when the GPS tracker crashed, it stopped logging trips. There's now an alert when that happens
Thanks,
Ryan
