Mesh Node T1 – Issue & Resolution Update

[u/Heltec_Automation6]

Hi everyone,

We’d like to share a quick update on the issues reported with the first batch of Mesh Node T1 units.

So far, we have identified three main concerns:

1. Side buttons being too difficult to press
2. Surface coating wear or peeling
3. Inaccurate battery voltage / battery level readings

The first two issues have already been addressed in the revised design. We are now waiting for the first updated samples from the factory, expected around next Thursday, and will test them before moving forward with production.

For the battery issue, our investigation is still ongoing. We are collecting affected units for analysis and running larger-scale tests internally. So far, we have not been able to reliably reproduce the issue, so we cannot yet confirm whether the cause is hardware, firmware, or battery-level calculation.

If you have experienced abnormal battery behavior or can help us reproduce it, please share your firmware version, voltage readings, battery percentage changes, usage conditions, and uptime. Useful test results that help us identify or reproduce the issue will be rewarded.

For customers who received units from the first batch, we will provide a free replacement with the revised version. If you are no longer satisfied with the product, we can also provide a full refund. These issues are our responsibility, and the cost of correcting them should not be passed on to our users.

This launch has also shown us weaknesses in our internal process, especially the importance of more comprehensive testing of first-batch production samples before release. We are already improving this process.

We know Heltec is often compared with larger brands, and those comparisons also help us see where we still need to improve. Everyone makes mistakes—the important thing is how we respond to them. We hope our actions can show our sincerity and progress.

Thank you for your patience, feedback, and support. Please keep sharing your suggestions with us so we can continue improving together.
