RPZ HA Lab
RPZ HA Lab is a private home-automation system run by one household on its own home server. It connects the family's own Google Nest thermostat to a self-hosted Home Assistant installation so the household can see the temperature, get alerts (for example if the heating or cooling is not keeping up, or the thermostat goes offline), and estimate daily heating and cooling costs on their own TV and phones.
Who can use it: only the members of this household, signing in with their own Google account. It is not a public service and does not offer accounts to anyone else.
Google data used: thermostat information from the Google Smart Device Management (Nest) API — temperature, humidity, mode, set points and whether heating or cooling is running — and the ability to change the thermostat's mode and set points when a household member asks.
