Devices
Homer controls what Home Assistant has. A device first joins the home — Home Assistant, through its own bridge or integration — and then you place it on the plan. Without the plan it still works, but you won't see it in the app or the web version.
What is supported
| What | How it joins the home | Where to add |
|---|---|---|
| Zigbee: lights, sensors, outlets, buttons | Through Zigbee2MQTT | Settings → Devices → Zigbee devices or “+” in the plan header |
| Matter | Through Matter Server and the “Matter” integration | Settings → Devices → Matter devices, on the web — the “Home” page |
| Tuya devices over Wi-Fi | Directly through localtuya, no cloud | Settings → Devices → Tuya devices, on the web — the “Home” page |
| Cameras from Yandex and Xiaomi | Through the Homer server and the go2rtc video server | Settings → Devices → Cameras, on the web — the “Home” page |
| Everything else in Home Assistant | Its own integration in HA | Placed on the plan like any entity |
Energy is not a device but metering: how much the home uses now and over a period, from device meters.
You can add a new Zigbee device by voice through the speaker — see New Zigbee device by voice.
How a device gets onto the plan
After pairing, the device shows up in the list on the add screen. On the right of the row is “place” or “to plan”.
- Tap the row — “Where to place …?” opens.
- Pick a room. In a multi-storey home rooms are labelled with their floor.
- The app switches to the plan with the device already selected in arrange mode. Drag it into place.
Other ways:
- Room card → “Place device” — places any HA entity.
- Settings → Devices → Devices on the plan → “Open” — all home devices by room and the HA entities they point to.
- Web, home editing — the device card: place it on the plan or remove it, change the entity. There is also “Blink” (the light blinks, so you can see it's the right one) and “Press on the device” (the Homer server waits for the first press on a device not yet placed and names it).
A smart outlet creates many entities in HA. Only one goes on the plan — the switch. Power and energy sensors attach to the outlet itself if the device has only one switch.
TIP
Buttons and remotes are not placed on the plan: there is nothing to show for them. Instead, their presses are bound to lights — see Buttons.
After placing
- A light placed on the plan joins the “All lights” group by itself and appears in Alice. Removed from the plan, it leaves.
- An outlet is not a light: it doesn't light up the room, “turn off everything” doesn't turn it off, and it isn't part of presets. Relay or outlet — you choose in the device settings.
- Sensors are display only: temperature as a label, motion as room highlight, leak and smoke as an alarm.
- “Replace entity” in the device settings changes the HA entity, while the point, height, name and groups stay. Handy for swapping a temporary light for the real one.
Remove a device from the home
On the add screens each row has “remove”.
| Protocol | What happens |
|---|---|
| Zigbee | The bridge asks the device to leave the network. If it doesn't answer, you can force forget it — then you'll have to reset the device itself by hand |
| Matter | The home revokes its keys from the device, and it accepts a pairing code again |
A removed device can only come back by pairing again.
