Sensor House Shop

Radios

The stick or adapter that lets Home Assistant hear Z-Wave or Zigbee sensors.

• Nabu CasaHome Assistant Connect ZWA-2The Z-Wave radio from the people who make Home Assistant: plug it in and every Z-Wave sensor on this shelf has something to report to.
• Nabu CasaHome Assistant Connect ZBT-2The Zigbee radio from the people who make Home Assistant, for a house whose sensors speak Zigbee rather than Z-Wave.
• ZoozZooz 800 Series Z-Wave Long Range USB Stick ZST39A small Z-Wave stick from the same maker as the sensors below, with the Long Range mode that reaches a detached garage or a far corner of the basement.

Hubs

Something to run Home Assistant on, if nothing in the house does yet.

• Nabu CasaHome Assistant GreenA small box that runs Home Assistant and nothing else, for a house where nothing runs it yet. Add a radio above for the sensors.

Leak sensors

For the leak recipe: on the floor at each fixture.

• ZoozZooz ZSE42 800LR Water Leak XS SensorSmall enough to sit under a dishwasher or behind a toilet, on a coin battery, reporting over Z-Wave to the leak recipe.

Temperature and humidity

For the freeze and humidity recipes.

• ZoozZooz ZSE44 800LR Temperature and Humidity XS SensorOne sensor for two recipes: humidity in a basement or bathroom, and a room cooling toward freezing before the pipes in it do.

Garage door sensors

For the garage door recipe: a tilt sensor on the top panel.

• ZoozZooz ZSE43 Tilt and Shock XS Sensor (VER 3.0)Mounted on the top panel of a garage door, it reports open when the door tilts up, which is all the garage door recipe needs.

Smart plugs

For the sump pump recipe: a plug that reports the power it passes.

• ZoozZooz ZEN15 800LR Power SwitchPlugged in between the pump and its outlet, it reports the watts the pump draws, which is what the sump pump recipe watches.
• ShellyShelly Plug US Gen4A Wi-Fi plug that reports the watts passing through it to Home Assistant without a cloud account, for the sump pump recipe in a house with no Z-Wave or Zigbee radio.

Backup power

So the hub stays up long enough to send the alert when the power goes.

• APC (Schneider Electric)APC Back-UPS 600VA, 120V (BE600M1)Keeps the hub, its radio and the router up through a short outage, so the watchdog and the sump pump recipe can still send their alert.
