Why it matters

This appears to be a contemporary external project focused on the same family of Bluetooth USB power meters.

It is relevant because it covers:

• UM24C
• UM25C
• UM34C

These overlap substantially with the devices targeted by this project.

Quick Notes

From a quick inspection, the project appears to be a web UI built around Web Bluetooth and live plotting.

Potentially useful areas:

• model naming conventions
• field naming choices
• unit scaling assumptions
• decoded status values
• command / payload interpretation hints
• UI ideas for live data presentation

Observations From Initial Review

• The repository describes itself as a web UI for UM24C/UM25C/UM34C power meters.
• It uses a JavaScript frontend rather than native iOS code.
• It includes explicit model mappings such as:
  • 0x0963 -> UM24C
  • 0x09c9 -> UM25C
  • 0x0d4c -> UM34C
• It also includes a charging mode map with values such as QC2, QC3, DCP1.5A, and SAMSUNG.

Limits

• It does not appear to target TC-66C.
• It should be treated as a secondary reference, not as ground truth.
• Any payload interpretation borrowed from it should be validated against our own code and captures.

Suggested Use

Use this project mainly for:

• terminology alignment
• comparison of decoded fields
• cross-checking known model identifiers
• identifying gaps in our current understanding

Avoid assuming protocol equivalence without validation.
