Somfy Geofencing Not Working? A Complete Fixing Guide

## Troubleshooting Somfy Geofencing Not Working

Geofencing is a powerful feature in your Somfy smart home system, allowing you to automate actions based on your location. You can have your blinds close, lights turn on, and thermostat adjust automatically as you arrive home, or have everything shut down as you leave. When it works, it's seamless. When it doesn't, it can be frustrating.

If your Somfy geofencing-triggered scenes are not working reliably, this guide will walk you through the most common causes and solutions in a professional and empathetic way, helping you restore the convenience to your smart home.

### Understanding How Somfy Geofencing Works

Before diving into troubleshooting, it's helpful to understand the basics. Geofencing uses your smartphone's location services (GPS, Wi-Fi, and cellular data) to create a virtual perimeter, or "geofence," around your home. The Somfy TaHoma app monitors your phone's location. When your phone crosses this boundary—either entering or leaving—it sends a command to your TaHoma hub to trigger a pre-programmed scene. The system's reliability depends on three things: your phone, your app settings, and your home network.

## Common Geofencing Problems and Solutions

Let's diagnose why your location-based automations might be failing.

### Symptom: Scenes Don't Trigger When I Arrive or Leave

This is the most common issue. You cross the geofence boundary, but nothing happens.

• Incorrect Phone Location Permissions: This is the number one culprit. The Somfy TaHoma app needs permanent access to your location, not just when the app is open.
  • On iOS: Go to Settings > Privacy & Security > Location Services > TaHoma. Set Allow Location Access to "Always".
  • On Android: Go to Settings > Apps > TaHoma > Permissions > Location. Select "Allow all the time".
• Power-Saving Modes are Too Aggressive: To conserve battery, your phone might be preventing the TaHoma app from checking your location in the background.
  • Go to your phone's Settings > Battery.
  • Look for 'App battery usage' or 'Battery optimisation'.
  • Find the TaHoma app and set its background usage to "Unrestricted" or "Don't optimise".
• Wi-Fi is Turned Off: Even if you're not connected to a network, your phone uses Wi-Fi scanning to get a more accurate and faster location fix than GPS alone. Ensure Wi-Fi is always enabled on your phone.

### Symptom: Scenes Trigger Unreliably or at the Wrong Time

Sometimes the automation works, but it's delayed or happens when you're still down the street.

• Geofence Radius is Too Small: A very small geofence (e.g., 50 metres) can be unreliable due to normal GPS drift. Your phone might think you've left and come back while you're sitting in your living room.
  • Solution: Open the TaHoma app and go to the geofencing settings. Increase the radius of the geofence to at least 150-200 metres. This provides a larger buffer and prevents false triggers.
• Poor Mobile Data Connection: As you approach home, your phone needs a stable internet connection to tell the Somfy cloud that you've crossed the geofence. If you're in an area with a poor mobile signal, the command might be delayed until your phone connects to your home Wi-Fi. While not always solvable, being aware of this can explain delays.

### Symptom: It Works for One Person, but Not Another

If geofencing is enabled for multiple users, everyone's phone needs to be configured correctly.

• Check All Devices: Go through the exact same steps above (Location Permissions, Battery Optimisation) on every single phone that is part of the geofencing setup. An incorrect setting on just one device can disrupt the logic of scenes designed for multiple users (e.g., "When the last person leaves...").

By systematically checking these settings on your smartphone, you can resolve the vast majority of issues with Somfy geofencing and enjoy a truly automated home.
