The folks over at home-assistant have confirmed the problem as well. I've made some adjustments according to their testing on the new rate limits imposed by August.
According to the home-assistant users, 10 seconds should still be acceptable for your polling interval (configurable in the plugin settings). What's changed:
1. I moved the polling to use the lockStatus API method rather than lockDetails. This allowed to have a single API call for both locks and door sensors.
2. The move to lockStatus means we no longer get the battery level. However this doesn't change very often so it's an okay trade-off. The battery level is updated when the plugin is restarted, or when you click the "Send Status Request" button. I'll likely implement a polling every few hours as well down the road.
I've posted a pre-release version on GitHub (
