Dear DTU users And lo and behold, I have now received an answer from Galaxus. You should apply for an account with Offgridtec via the Alltron web page (presumably the general importer?). See also: https://alltron.ch/de/product/1459410 Under Documents you will find the application form for the account and the email where to send the form. You can also try it, I'll try it and get back to you. LG Urs S-Miles account creation The creation of the S-Miles account can only be done through the dealer of the DTU. You will find the account creation form in the download area. After you have received the DTU, please send the completed file by e-mail to technik@offgridtec.com with the subject "Hoymiles User Account". Offgridtec will then create your account and send you the access data.
