mumu.land Home Bridge

A private, single-household connector that lets the owner of mumu.land see and control their own Google Nest thermostats from Apple Home.

What it does

The bridge runs Homebridge on a small server in the owner's home. Through Google's Smart Device Management API, it reads each thermostat's temperature, humidity, mode and set points, and passes changes made in Apple Home (for example, a new target temperature) back to the thermostat.

Who it is for

Only the owner's household. It is not a public service: there is nothing to sign up for, and no one outside the household is asked to connect an account.

Google permissions it asks for

• Smart Device Management (sdm.service): read thermostat status and change its settings.
• Cloud Pub/Sub (pubsub): receive change events from the thermostats, so Apple Home updates promptly instead of polling.

How that data is handled is described in the privacy policy.
