Thanks. 
strange indeed !
Anyway I spoke too soon 
every command I send gives me an error 400 and the heaters donât do anything. Would you have any suggestion please ?
EDIT : heaters are âSAUTER Gyaliâ.
Could you enable the information log and then send a command, when you get the error, go back to the log and Send it.
Sure. Just did it.
Not sure Iâve done it right, I have this one sent a08b61a8-d38b-42cf-aec4-cd54d1fb8fab
And also, the information log
The second one is the best one, but Iâm not seeing any errors. Did you wait until you got the error before sending the log?
Ok, noted. I did get the error. Iâm gonna do another one with several tries and commands.
Done : id 1314733367
