It’s exactly the device from the linked issue on github. Also the device is listed on github with gold status and silver at my current version 2.24.2
Manufacturer: _TZ3000_j1v25l17
Model: TS011F
Edit: I’ve added the same file to my personal config, as @jan666 mentioned above and restarted my server. Now i finally see the additional features (voltage, power, current and firmware version).
Still a riddle, why the original file in /usr/share/deCONZ/devices/ isn’t active.
