Mon hms 1000 2T n’est pas reconnu

Zut alors, what's that? Let's update that thing (and kick the seller in the shins ;-) Flash Memory Size 4MB, I suppose? Then download this firmware 1st: https://github.com/hoylabs/OpenDTU-OnBattery/releases/download/2024.10.22/opendtu-onbattery-generic_esp32_4mb_no_ota.factory.bin

J’ai téléchargé

Comment savoir la taille de la mémoire flash ? Car je ne sais pas la taille

Après je fais quoi avoir téléchargé ?

The update process itself is described here: https://opendtu-onbattery.net/firmware/flash_esp/#__tabbed_1_4. That should do the trick.

Download the flash tool, connect you dtu via usb & follow the steps on the screen shot.

Merci beaucoup
