"Should I use Notion or Home Assistant as the primary controller?"

"Best practice is to use Home Assistant as the central controller and Notion as a bridge or radio provider only. This avoids dual-management conflicts and gives you one place to manage all automations. A managed setup configures this correctly from the start."

"Can Notion router data replace dedicated presence sensors?"

"Router-based presence detection is convenient but less reliable than dedicated sensors. Phones disconnect from Wi-Fi in sleep mode, guests may not be on your network, and latency varies. A managed setup combines network presence with other signals for accuracy."

"How do I keep Notion hub firmware updates from breaking my smart home?"

"The best approach is to disable automatic updates on Notion hubs and test updates manually before applying them. A managed Selora setup does this automatically — testing firmware in a staging environment before rolling it out to production."

Notion & Home Assistant

Network & Hubs

Notion integrates with Home Assistant to bridge network infrastructure and smart home hubs into a unified system. Connect routers, mesh networks, and device bridges that act as the backbone for your smart home devices.

With Notion connected to Home Assistant, your network infrastructure becomes visible and automatable. Track connected devices for presence detection, monitor network health, and manage hub-connected devices alongside direct-integration devices.

How Notion Works with Home Assistant

Getting Notion connected to Home Assistant and running reliably.

1

Connect your hub

Add Notion through the integrations panel. Hub-connected devices, network clients, and system health metrics appear as entities in Home Assistant.

2

Device tracking & presence

Use Notion network data for presence detection. Know who's home based on which phones are connected to your network — no app required on their devices.

3

Network-aware automation

Build automations based on network state. When a specific device connects or disconnects, trigger scenes, adjust settings, or send notifications.

Common Notion Issues

The problems installers run into with Notion and Home Assistant — and how a managed setup prevents them.

Hub firmware update breaks child devices

When Notion pushes a hub firmware update, the Zigbee/Z-Wave/Thread radio behavior can change, causing child devices to drop off the network. Recovery requires manual re-pairing.

Dual management conflicts

Managing Notion hub devices through both the manufacturer's app and Home Assistant simultaneously can cause state conflicts. Changes in one system may not reflect in the other.

Presence detection false positives

Using Notion router data for presence detection can be unreliable — phones in sleep mode may disconnect from Wi-Fi temporarily, causing false 'away' triggers that arm the alarm or adjust the thermostat.

mDNS/SSDP discovery blocked

Enterprise-grade Notion networking equipment often blocks multicast by default. This prevents Home Assistant from discovering devices, requiring manual firewall and IGMP snooping configuration.
