Does this work with the new firmware version 2.1.1_0159 exploit?

[kcajjones]

A new exploit for firmware version 2.1.1_0159 has been discovered here:
https://github.com/atc1441/ATC_MiThermometer

After flashing the 2.1.1_0159 exploit, can the normal OTA flashing procedure work to get this ZigBee firmware working?

Yes, it should work. After flashing to ATC firmware with that firmware you can convert it to zigbee according to the instructions

When trying to pair the device via bluetooth on Telink Flasher v6.2, I get the following errors:

I used this web flasher tool successfully from the latest (as of 21/01/25) exploited firmware for 2.1.1_0159 https://pvvx.github.io/ATC_MiThermometer/TelinkOTA.html

Flashing the ATC_ota_40000.bin file took a long time (~300 seconds). I then removed the battery and re-inserted. I was then able to connect again and flash the z03mmc.bin file. The flash was a lot faster and rebooted into zigbee pairing mode. It was immediately available and connected to my Home Assistant server via ZHA.

The same method worked for me. Just finished!

I have some new thermometers with firnmware 2.1.1_0159, installing the exploit works fine the ATC firmware works, but after installing z03mmc via OTA they seem bricked, I can only recover them by installing the ATC firmware again via UART.

Installing z03mmc via UART also doesn't help, the don't show anything on the display and also dont seem to send anything on zigbee my ZHA can't find them. Did I get a new hardware revision?

Did you use transitional ATC_ota_40000.bin before flashing zigbee?

[Fredyy90]

yes, the firmware seems to work, display shows data and bluetooth is active, as soon as i flash z03mmc.bin v1.1.0 its just dead

@Fredyy90 Did you manage to solve the problem?

Same/similar problem!
In fact you notice the device is working but does not show image.
I can get in the mode to do Join to the Zigbee network (3 seconds GND and RST) and then see the equipment on the network without problem but without image on the display, I tried everything but without luck
This only happens with the last ones I bought, I have 6 other working perfectly. Curious that if you return to flash the firmware ATC (V4 or V5) works all right (via Bluetooth)

Hardware Revision String: B1.5
Software Revision String: 0159
Firmware Revision String: 2.1.1_0159

Same problem on two separate devices 2.1.1_0159. One device the screen never turns on while the other device the screen does not refresh. Both devices do show up in zigbee2mqtt and report correct values.

There's a NB saying this version is currently not supported. I flashed it to the ATC version following This video but now I'm not sure where to go. I wanted to use Zigbee since I have a zigbee hub, but not a bluetooth one.
