Dear Zendure Users,

We are well aware that following the recent update to APP V6.3.0 and the June firmware release, some users have experienced usage issues or abnormal behavior, which has caused you inconvenience. We sincerely apologize for this.

To locate and resolve each user's specific problems more quickly and accurately, we have opened this thread as an exclusive collection channel for HEMS 2.0 troubleshooting and feedback.

If you encounter any anomalies while using HEMS 2.0 (e.g., device stuck in standby, power anomalies, update failures, App display errors) and the dedicated FAQ Announcement for this update (link below) did not resolve your issue, please submit your information using the format below. We will prioritize the feedback collected through this channel and assign an after-sales engineer to follow up with you one-on-one.

Important Notes
** Do not post private data: To prevent leaks, please do not share your SN or email in public comments. Send complete details exclusively via email.
** Check the FAQ first: Our FAQ Announcement resolves most known issues (e.g., incorrect LAN connection, SOC lower limit standby, error codes 223/224, custom mode settings). Self-service is often much faster than waiting for manual support.
** Resubmit unresolved issues: If you previously reported an issue via other channels (e.g., Facebook groups, other forums, WeChat) without a resolution, please resubmit it here for centralized, priority handling.

Thank you for choosing Zendure, and thank you for your patience and understanding. We are working hard to make HEMS even better.

Your Zendure Team
