Doubt with installation on B1.4 and B1.5 sensor #70

Open kikher opened 11 months ago

kikher commented 11 months ago

Hi, I'm new to this. I have been reading a lot about switching from BLE to Zigbee and I am interested. I have 2 B1.4 sensors and 4 B1.5 sensors. I have seen that there are two way to switch versions. One via a transitional firmware (1) and one direct with Flasher version 6.9 (2).

  1. https://github.com/devbis/z03mmc
  2. https://github.com/pvvx/ZigbeeTLc

Which of the two is more advisable to follow? Can it give me any problem? I have B1.4 sensores in version 1.0.0_0001 and B1.5 sensors in version 1.0.0_0130.

Thank you very much for any help you can offer me.

Both firmware versions are in beta testing. Firmware from devbis is in the general update lists for all Zigbee devices and can be updated automatically in some applications. Firmware from ZigbeeTLc will not be published in the general update lists until they pass the beta testing stage. Update only manually.

To return the thermometer to work in BLE, you need to rewrite the files from the ATC_MiThermometer - zigbee_ota to the local OTA updates directory for your integration working with Zigbee (and run the update).

Thank you very much for your comment, I will use the Firmware from devbis.

I'm not very clear about the last part you tell me. I had read that it can only be returned to BLE by USB... but I understand that through my Zigbee platform I can return it to BLE. I use deCONZ and it has the OTAU Update option. Does this mean that using this function I could bring it back to BLE without a USB USRT?

I have accessed the link ATC_MiThermometer - zigbee_ota and see several files all ending in .zegbee but not .ota or similar, any of them would work to return the LYWSD03MMC to BLE.

Sorry for asking so much but before I get to flashing it I want to make sure I understand everything right and know if it has a way back if I am wrong about anything.

The extension after the file name does not matter.

I have already made a version of the Zigbee OTA firmware that converts the thermometer back to the BLE version and for the devbis firmware. This file is "1141-0203-99993001-ATC_v46.zigbee".

The USB-COM adapter is not used to flash thermometers Xiaomi LYWSD03MMC with any firmware options from ATC_MiThermometer or ZigbeeTLc. Only if you recorded the wrong firmware version using third-party files. Only BLE or Zigbee OTA is used.
