Problem when i first powered the Device with USB C

[ghost]

The Battery is not here already, so i powered the Device by USB-C. All went ok, was able to integrate with Home Assistant. The labels i was able to change. All ok so far. When i removed USB-C and repluged, Display showed Reboot, the Display flashed Black / white. And the Labels hav the Values, thadvi changet to. Problem now is, no Light, when i Push a Button, not changing to Temperature, when i Push for 30 Sec, no Reset is happening. Is this a known Bug. Is there a Solution for my Problem? Best Regards Daniel

Could you please answer this questions so I can better understand the issue:

1. Does it display RESTART... if you unplug and replug USB-C?
2. Does it display RESTART... if you press RST button inside the case on the PCB?
3. Is the display refreshing at all in any case?
4. Did you try using a different power brick or connecting it to a computer USB port?

Thank you for your Help!

1. Does it display RESTART... if you unplug and replug USB-C?

• Yes

2. Does it display RESTART... if you press RST button inside the case on the PCB?
   • Yes
3. Is the display refreshing at all in any case?
   • Yes, after RESTART... it refreshes several Times (turning from inverted / black & white ) for maybe 5 Times.
   • It is not sending any Messages to MQTT and i cant' find it in my Network
   • And when i push the 6 Buttons the LED's inside are not lighting up
4. Did you try using a different power brick or connecting it to a computer USB port?
   • Yes, with my Macbook it's the same

I didn't tested it with the Battery, because it's not here already

i couldn’t even reach the setup part when it was only connected via usb-c, once i plugged the battery, it worked as intended. Maybe try that.

funny enough, i got a battery from a vape shop

@marthaler when you press any of the 6 buttons nothing happens? LED does not blink and the display doesn't refresh?

Could you please flash this to the device using esptool: 2301-174_v2.0.4.bin.zip (extract the zip first)

The command is: python -m esptool --port PORT --after no_reset write_flash 0x 02301-174_v2.0.4.bin

Put the device in boot mode by pressing the reset button while holding the boot button. LED under lower left button will light up. Replace PORT in the command with the serial port on your computer or omit --port to detect it automatically.

You will have to do the setup again after flashing.

@nplan: Yes that was the case, no LED. I was was just beginning the flashing with the Version you provided. And i was just pluging the device in one more Time. With another USB Cable directly to my Computer... And now everything is working as expected. So i will not flash it. Unless it is useful for you...? One more thing: I tested in different WLAN's with the Same ID / and Password. Maybe my Problem was because of that. I will for sure test again in all of this Networks.

Thank you so much: Great work, great Product. I will order some more if available Again :-)

Great to hear that, thanks. Although it doesn't make any sense to me why that would happen. No need to flash it, if it works. Just let me know if you have problems again.
