Why Does My SimpliSafe Say Wireless Interference Detected?
- Garage door openers operating on similar RF frequencies
- Baby monitors especially older analog models
- Wireless weather stations transmitting data
Problem Description
Your SimpliSafe base station announces Wireless Interference Detected and sends notifications to your app. This happens when the base station detects radio frequency signals that may interfere with communication between the base station and your sensors. SimpliSafe devices communicate using RF frequencies around 433MHz which can be disrupted by other wireless devices in your home or external sources. The base station is designed to alert you proactively when it detects potential interference that could prevent sensors from communicating during an alarm event. Most interference is temporary and resolves on its own but persistent interference requires identifying and removing the source.
Symptoms
- Base station announces Wireless Interference Detected repeatedly
- App shows wireless interference notifications at random times
- Interference alerts happen at the same time every day
- Sensors occasionally show not responding after interference alerts
- Base station alternates between interference detected and resolved
- Interference alerts happen when using specific devices in the home
Recognize these? Here's what usually causes it.
Common Causes
- Garage door openers operating on similar RF frequencies
- Baby monitors especially older analog models
- Wireless weather stations transmitting data
- Ham radio or amateur radio equipment nearby
- Smart home devices using 433MHz frequency
- LED lights with cheap wireless controllers
- Remote controlled outlets and switches
- Car key fobs especially aftermarket ones
- Nearby airports or air traffic control towers
- Solar panel inverters or high voltage power lines
- Wireless doorbells on similar frequencies
- Construction equipment or cranes nearby
Most fixes happen in the first 3 steps.
Do not ignore persistent wireless interference alerts that happen multiple times per day. While occasional interference is normal frequent interference could indicate a device that will prevent sensor communication during a real emergency. SimpliSafe support can review your system logs to determine if interference is affecting sensor reliability.
Step-by-Step Solution
Identify When Interference Occurs
Check your SimpliSafe app notification history to identify when interference alerts happen. If they occur at specific times this points to a device that activates on schedule. Garage door openers trigger interference when used. Weather stations often transmit at regular intervals like every 5 or 15 minutes. If interference happens randomly throughout the day look for devices you use intermittently like baby monitors or wireless switches.
Check Common Interference Sources
Walk through your home and identify devices that use wireless signals. Common culprits include garage door openers within 20 feet of the base station, baby monitors, wireless weather stations, LED light strips with RF remotes, smart plugs using 433MHz, and any device with a small remote control. Also check for ham radio equipment. Make a list of all wireless devices near your base station.
Relocate the Base Station
Move the base station at least 10 to 15 feet away from suspected interference sources. Place it in a central location in your home away from the garage, away from weather stations, and away from clusters of smart home devices. Avoid placing it near windows if you suspect external interference from nearby airports, construction sites, or power lines. The base station should be in an open area not inside cabinets or closets.
Test by Disabling Suspected Devices
If you identified a suspected source temporarily disable or unplug it for 24 to 48 hours. Monitor your SimpliSafe app for interference alerts during this period. If alerts stop you found the source. For devices you cannot remove like garage door openers the solution is to move the base station further away. For devices like weather stations consider replacing them with models using different frequencies.
Check for External Interference Sources
If no internal source is found the interference may be external. Check if you live near an airport, military base, radio tower, solar farm, or high voltage power lines. Move the base station to the opposite side of your home away from the external source. If you live in an apartment building a neighbors devices could also cause interference. Contact SimpliSafe support for assistance if external interference cannot be avoided.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
The Wireless Interference Detected alert does not mean your system failed. Your sensors will still trigger alarms if someone breaks in. The alert is a proactive warning that communication quality may be reduced. If you receive this alert but your system arms and disarms normally and sensors respond in test mode the interference is not critically affecting your security.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
