Eufy Doorbell Overheating? (Easy Solutions to Keep It Cool)

If you want to prevent the eufy doorbell overheating issue, you should keep the device in an area where the operational temperature won’t exceed 122°F–(50°C).

When the thermal margin is exceeded, the doorbell will turn off and display the following message in the eufySecurity app:

• “Doorbell has turned off due to overheating”

That’s a protective mechanism of your device, which automatically powers off the eufy doorbell when the heat is too much.

This mainly happens on wireless doorbells, which are designed to prevent the battery and hardware from lethal damage from extensive heat.

Well, even during the warm summer season, there are various things you can do to stop this!

How to Prevent eufy Doorbell Overheating in 7 Easy Steps?

Important: Apply as many of the following methods as possible–a combination of techniques can achieve greater results, rather than only one.

1. Optimize Doorbell’s Positioning

The most important step to begin with is optimizing the position of your eufy doorbell.

The area in which your device is set up includes two critical factors:

When combined, meaning that your doorbell is exposed to direct sunlight without being able to “breathe” overheating is almost certain.

We have prepared a few handy tips you should employ.

1.1 Avoid Direct Sunlight

If you have a wireless eufy doorbell, this means that relocating the device is not going to be as complex as with hardwired units.

That’s why if possible, move your doorbell to a shady location or a spot where the device wouldn’t be exposed to direct sunlight, at least not all of the time.

Note: Skip this step if you’re experiencing overheating with a wired eufy doorbell.

1.2 Improve the Airflow

Sadly, eufy doorbells are designed without visible ventilation openings, meaning that the natural airflow around the device is crucial for normal operating temperature.

So, verify that the doorbell is not in an enbclosed space and that there is nothing trapping the generated heat from escaping.

Note: Avoid the use and presence of nearby overhanging plants/branches, protective doorbell covers, nearby light fixtures, and contact with metal surfaces.

2. Cover the Doorbell via Sunshade

If you’re using a wired eufy doorbell and adjusting the positioning is not possible, sunshade is the best possible way to prevent overheating. 

• The sunshade could be literally anything–a piece of cardboard, repurposed PVC pipe, a piece of wood or plastic, and so on…

The idea is to install a DIY sunshade above your eufy doorbell and prevent direct sunlight from attacking your device from above all day.

This will guarantee a decrease in the unit’s operational temperatures and hopefully prevent overheating.

3. Turn OFF the LED Doorbell Light

As insignificant as it may sound, the LED light on the front of the doorbell can greatly contribute to increasing the internal temperature by being lit all the time.

Yes, this is a small step against overheating, but considering that the light constantly engages the battery, a small amount of heat will be generated non-stop.

Here’s how to disable the LED light on the eufy doorbell:

1. Open the eufySecurity application on your phone.
2. Then go to the Settings and enter the Smart tab.
3. Select Mode and enable “Optimal Battery Life”.

This will not only increase the lasting time of the eufy doorbell battery but will also contribute to decreasing the overall heat generation. 

Now, continue with more optimizations against overheating.

4. Decrease eufy Motion Sensitivity

The motion sensitivity is how much of an action is required in front of your doorbell to trigger an event, thus initiating a recording.

The more frequently the doorbell captures events, the more battery it uses, and the more heat is being generated.

So, lowering the motion sensitivity will prevent the camera from capturing events whenever the wind blows harder or a cat walks by.

This will decrease battery usage and lower the heat.

Here’s how to decrease the motion sensitivity on the eufy doorbell:

1. Open the eufySecurity app and go to Settings.
2. From there go to Smart and then Automation.
3. Pick Motion Detection → Detection Sensitivity.
4. Reduce eufy’s sensitivity to 2 or 3 at maximum.

This will prevent the number of false alerts, which will lower the amount of battery usage and decrease the generated heat during the day.

Note: Feel free to explore the lowest sensitivity option of “1” to check whether it works for you!

5. Configure Doorbell Activity Zone

So, if you don’t want to lower your sensitivity and decrease the level of security, to prevent the constant event triggers, thus utilization, you simply limit the activity zone.

You can define the specific area of the camera’s view, in which the device will trigger an event if motion is caught.

You can keep your sensitivity high, but avoid false alerts by excluding parts of your camera’s view.

This will limit alerts, decrease battery usage, and lower the amount of generated heat.

Here’s how to define your eufy doorbell activity zone:

1. From your eufySecurity app go to Settings.
2. Choose Motion Detection → Activity Zone.
3. Tap on the ⊕ icon and configure your area.

By changing the shape of the activity zone, you can limit your eufy doorbell from only monitoring this specific zone.

That’ll stop the constant and false detections, which will reduce overheating.

6. Lower your eufy Retrigger Interval

Increasing the retrigger interval is another way to combat the eufy doorbell heating issue, which will again reduce the number of false motion event triggers.

The retrigger interval is the time the doorbell will wait before triggering another detection event, in cases when the motion is ongoing.

For instance, when the retrigger interval is set to 5 seconds, your doorbell will trigger an event and start capturing.

If the motion continues after these 5 seconds, your eufy will trigger another event, again and again, increasing utilization and heat.

In contrast, if you set the retrigger interval to 60 seconds, your doorbell will wait a full minute for the motion to disappear before triggering an event.

• To reduce the retrigger interval go to Settings → Smart → Automation → Customize Recording → Retrigger Interval → 5s to 60s.

The bottom line is, that the more frequently your doorbell triggers detection events, the more heat is generated, and the more likely overheating is to occur.

7. Limit the Use of Eufy’s Live View

If you’ve set up a system for 24/7 monitoring of your eufy Live View, know that this keeps your doorbell engaged all the time, hence overheating is inevitable. 

The more you view the live feed from your doorbell the more heat is generated, so if you have some sort of monitoring system, we strongly recommend dropping this idea.

When you’re done viewing the feed, close the app to prevent background usage, which is enabled by default on most smartphones.

eufy Doorbell Overheating – The Best DIY Solution!

Well, we understand that sometimes it’s impossible to prevent overheating, especially during the summer when the temperatures outside are over 86°F–(30°C).

In those cases, a DIY solution is the best possible way to keep your eufy doorbell cool. If you’re a tech enthusiast you’ll like this one!

You need a small 12V computer fan, as well as a 12V DC power adapter.

You can then connect this fan to the power adapter by stripping the adapter wires and exposing 1 inch of the copper.

• The red wire is positive (+)
• The black wire is negative (-)

When you connect the fan to a power adapter, test it by plugging it into an outlet.

Then you can use any type of power extender to lead some power near your eufy doorbell.

Finally, use a zip tie to attach the fan blowing directly against your doorbell. This will surely stop the overheating!

Quick Tip: You can use a smart plug to automatically turn off the fan during the night and turn it on during the warmest hours of the day.
