@matkor it is currently not possible. https://github.com/mysensors/MySensors/issues/1312 suggests a solution but there has been no forward progress lately. flatsiedatsie created this issue in mysensors/MySensors open Proposal: UX extensions #1312

@Yveaux I also add the delay to not ddos the gateway. When I did the MySensors workshop, 20 people started to connect to the gateway almost at the same time. And they got Funky messages. Since then I do a delay. But it would probably be better to add a random time to the delay. Something like 20ms + random( 0 - 30 ) ms. That way you don't get the ddos effect. Sonoff had the same problems with their solution a couple of years ago, when the servers went down. All Sonoff devices tried to reconnect almost the at the same time. Which caused a ddos xd

@martinhjelmare Wow thank you so much. I've cleared the eeprom and now it gets node id 1. After removing the persistence file the sensor now shows on the web interface.
