- Works with Legrand

Hi Leslie,Thanks for your reply and for sharing the ZigBee 3.0 compatibility mode option.The main reason we are aiming for a local integration is system stability and, most importantly, real-time status feedback. With cloud polling, the response times and event synchronization are not as consistent, which is critical for automation systems like Elan.I have already tested a similar local integration using a Somfy gateway, and it worked well from a connectivity standpoint — however, I lose important configuration features that only the Legrand Magellan gateway provides, such as enabling the dimmer mode for the K4411C, setting minimum/maximum load thresholds, and other advanced parameters.At this point, I’m developing the driver for Elan to integrate with the Legrand Netatmo cloud API. I’ve managed to:<ul data-start=”927″ data-end=”1220″><li data-start=”927″ data-end=”1047″>Register the application and complete OAuth2 authentication (client_id, client_secret, access_token, refresh_token).<li data-start=”1048″ data-end=”1110″>Implement token refresh logic to handle hourly expiration.<li data-start=”1111″ data-end=”1220″>Send control commands successfully through the API test environment (“Try Out”) using its provided token.However, I’m still having difficulty understanding how status feedback works in the API. I’ve tested webhooks as per the documentation, but retrieving the <code data-start=”1381″ data-end=”1390″>plantId and mapping it to devices for state updates remains unclear. Without this, real-time synchronization is incomplete.Any additional technical guidance on how device state feedback is delivered through the API — or best practices to ensure instant updates — would be extremely helpful.
