1 year ago The values are fetched directly form the API using the history. That interface is rate limited, so the app only pulls the data in once per hour. At one point I synchronised it to on the hour, but that meant all the Homeys fetch the data at the same time and triggered the rate limit :-). Now it is depends on when Homey starts, plus a random delay, to ensure the calls are interspaced as much as possible.
