Yeah, we're aware of the issue. It's apparently a problem with a load balancer somewhere in Amazon's server park, so sadly not much we can do right now.
The way we've set things up, I'm afraid it would be a major project for us to make the apps talk directly to the Almond+, but point taken, especially for situations like this.
Worst case, the local web UI will talk to the sensors, so that's the fallback at the moment.
