Silicon Labs Flasher add-on to flash Silicon Labs based radios.
By default this add-on flashes the firmware to use Zigbee (Silicon Labs EmberZNet Zigbee stack).
NOTE: Make sure no other add-on or integration is using the radio. In particular disable the Zigbee Home Automation integration and the Silicon Labs Multiprotocol add-on.
This add-on allows you to flash firmwares using the Gecko Bootloader file format (gbl). By default it comes with firmware for Home Assistant SkyConnect/ZBT-1 and Home Assistant Yellow to flash Zigbee.
