I would expect that the token I posted above didn’t work as it’s unique to the account I used to build the example. In fact, I think I changed a few characters of it just out of a sensor paranoid internet security
As for the , I haven’t seen it with this example, but I remember when I was doing this some months ago (and the process was a little different) that I would occasionally get that response when trying to pull too much data at once. If you were going for a very large time range, it may be worth trying a smaller one to see if that pulls some data. I remember at that time that I had to break a few months of sensor history pulls into 3 or 4 pieces.
If its still not working for you, and you’re comfortable with me in your account, I’m happy to help assist with pulling info, or at least getting a URL that you can use for your account as a proven example. I know the process above is convoluted and I don’t want to burn you out probing around our raw systems, so just send me a PM with your account info and what sensor data/time ranges your interested in and I’m happy to spend some time pulling data or troubleshooting if I run into the same wall.
