WattAudit makes your energy audits more efficient and secure. Before arriving on site, prepare your personalized audit. The listener uses his personal identifiers to connect, his position being immediately geolocated for optimal traceability. On the site, the intuitive form of WattAudit guides the auditor in real time, allowing the addition of photos or scans of documents. The application guarantees data security by automatically saving each time you enter it. Data entry is facilitated by the numeric keypad, and required documents and photos are indicated by an icon. At the end, the beneficiary and the listener digitally sign the document, with automatic geolocation and time stamping to ensure integrity. Finally, the form is saved in the TEZOS blockchain and deposited in your personal space in PDF, with a CSV export option.
