Editorial interest 85/100 Selection signal · not a rating of the site

An open-source USB installer gives Nest Learning Thermostats local MQTT, Matter, and Zigbee options for Home Assistant, without a Google account.

Landing page captured for the 2026-10-18 issue.

For: Nest owners using Home Assistant without cloud dependence
Worth noticing: The installer embeds recovery firmware and backs up the thermostat’s entire NAND before changes.

Field notes

The installer is described as a single executable for Windows, macOS, and Linux, with recovery firmware embedded. The support table distinguishes the third-generation model, listed for MQTT, Matter, and Zigbee, from the second-generation model, where Zigbee remains untested. The included shareware Doom episode is played by turning the thermostat ring to walk and pressing it to fire.
