Hello,

when I try to register my sensor, I have a message saying “sensor ID is already registered”. I do not know who uses the same ID and how to contact him.  
I already sent an email to tech@sensor.community but no reply yet from Rjako.  
If it is not possible to delete the current sensor from the database, is it possible to set a new unused ID within esp8266 code ? If yes, how can I choose a free ID ?

Thanks
