    It's probably TuyaMCU device, so it should work with OBK, but we will need to figure out dpIDs. We can try if you order one, and help you step by step.

Topic summary

LABEL_AI_GENERATED
The discussion concerns whether an AliExpress smart fuse can be flashed with OpenBeken or Tasmota. It is identified as likely being a TuyaMCU-based device, so OpenBeken should be possible, but the key step is determining the correct dpIDs. After the device is received and opened, two variants are reported: T35 with display and T1-U-HL. The enclosure is welded and should be opened from the bottom. The suggested procedure is to first make a 2 MB backup of each flash chip, then follow the TuyaMCU flashing and configuration guide to map dpIDs for Home Assistant.
