I reconnected the service just today after the Neato service was misbehaving badly the day before. Could it be there was a temporary problem with the Neato services, maybe try again later?
Also, I recommend installing the test version of the Neato app. The “normal” version has a bug with reconnect times which was fixed ages ago but never set live.
The app hasn’t been updated verly long and is a bit shakey. If you can’t get it to work there is a workaraound possible so you can start the robot through IFTTT (using webhooks, since the IFTTT service is about to be discontinued):.
I created a tutorial today using this as an example
