At the office, at home and on site

Keep working wherever you need your diagram

  • Prepare at the office. Draw your diagram in the browser on your Windows PC or Mac, without installing anything.
  • Check at the installation. Open the project on your iPad or tablet and compare the diagram with what you see on site.
  • Continue at home. Sign in on another computer and open the same saved project. No files to transfer.
Together on the same project
  • Invite colleagues to your account. Everyone has their own login and access to the same projects.
  • Let a colleague review or finish your diagram, without emailing files back and forth.
  • Connect your CRM. Integrations with CRM systems are available. Get in touch to set up the integration.

Yes. You can keep editing your project and export it to PDF again, without paying for that project again.
No. The subscription ends after the period you chose. Your projects and previously created PDFs remain available. If you want to export new PDFs after that, you buy a new subscription period or a project credit.
No, but 1wire assumes you know what your installation consists of: which circuits, with which protective devices and which cables. 1wire draws what you enter, but doesn't decide for you what belongs in your installation. If you know your installation, even as a private individual, you can draw your own diagram with it.
No. Upload a scan or photo of the existing diagram and 1wire turns it into an editable diagram in 5 to 10 minutes, which you then complete. Handy for renovations, extensions or re-inspections. Read how scanning works.
Yes. With the Import Trikker button in your project list, you open a .trik export directly as an editable 1wire project.
