I installed Home Assistant 2026.8 in docker, and installed a new version of SLZB-OS on my SLZB Ultima, both of which supports bluetooth proxies on the Ultima without having to uninstall / unflash it and install /flash ESPHome. There’s now documentation here: SMLIGHT SLZB - Home Assistant.
However, I still need help with setting up the Thorbolt MK1: Setting up Thorbolt MK1 Doorknob with SLZB Ultima?
