Not sure if it matters, but when I copied from the console into my editor (vscode) it highlighted some low ASCII chars - see the screenshot. They are included in the output pasted here as well.

There's something wrong in the data for sure, when looking at the main Tasmota page the text I see for "Message 1" changes slightly. Here are ones I've seen so far:

• PAS DE MSSAGE (\x05 in place of the missing char)
• PAS DE MESSAE (\x07 in place of the missing char)
• PAS DE MESSAGE (correct)

Unfortunately my primary Linky for power consumption is in mode historique and the EDF people never reacted to my request to change it so I cannot test if it's the same problem there or only on the production linky...

Edit: I just realized that something truncated long lines from the output I posted above... here's one captured via usb/serial connection. Doesn't contain the ASCII garbage but the full data in case it's useful...
