Good evening 
Everything is in the title: I create two MQTT topics whose external ID is different, but seen as identical by Gladys, as follows :
On the code side, the IDs are defined like this :
And seen like this in MQTT Explorer, when they are initialized by code :
So, I don’t understand why they are rejected by Gladys ?
Help … 
Hi @jean_bruder! The problem comes from the external IDs of your features, which are identical they must be unique across all of Gladys
Hello @pierre-gilles
Indeed, while rereading the excellent documentation available on the Gladys website, which concerns the use of MQTT (MQTT | Gladys Assistant), I noticed the slight difference that exists between the external ID and the feature’s external ID …
So it’s fixed, and it works perfectly 
Thanks again 
Have a nice day,
Jean
