Entry sensor outside

Has anyone used the entry sensor outside?
Now that the sensors can be linked to cameras I might get round to using mine but my doors are now setup with a different system that’s much smaller

so I want to use these for garden gates embedded into the frame

As they are rated to internal use I can imagine the PCB isn’t conformally coated

Has anyone coated an entry sensor or sealed the case?

Has anyone tried them outside unmodified?

Anyone know what the max range is?

I definitely would love to be able to use them outside, rolling shutters or gates would be great use cases.

@Mengdi @AnkerSupport
Will it be ok to use silicone conformal coating on this part of the circuit?
I know it can affect RF circuits but I’m not sure what frequency it starts causing problems

Hey Guys! Thanks for sharing your thoughts here :slight_smile:

For the eufy entry sensor, we are so sorry to let you know that the it is for Indoor-use Only.

We will keep improving our prodyct for differencet usage so thank you so much for your feedback on this case.

If we can offer further assistance in the future, please do not hesitate to contact us again. We’re always ready to help!

Thanks again for all your support. Have a lovely day!

Well I’ve conformally coated the PCBs, I decided to use acrylic coating as that’s what I’m used to using

You can just about see the coating

Now outside, we’ll see how they do, just bolted them to the gates for now to make sure they work ok & survive some heavy rain, after I’m happy they’ll be ok then I’ll embed it into the gate & frame

How do you automate? All I get from the sensor is a push notification on my mobile.

For eg. I cannot get a (basic) sound notification in my home base when the sensor is opened, or trigger the doorbell to start recording.

Sad, that eufy choose to isolate themselves, and doesn’t integrate with other systems.

I have them linked to get a camera to record & chirp through the homebase

Thanks that is awesome, but, apparently this is available on next firmware. My current firmware from 2nd of May, does not have Automation option.

I contacted support to manually push the new firmware to my device.

Mine last updated a month ago

The firmware update was pushed by eufy support to and now I have the Automation option under Security. And also now I have the Chirp tones under the entry sensor, as shown by @Haloweenhamster. Thank you for pointing out the chirp option.

Still, the Homebase does not come under Action device when creating automation (as it should be as it is a speaker as well). For eg., if the front door sensor is opened for more than 1 min trigger the chirp for, let’s say, every 15 sec 10 times or until the door is closed.

[This should be moved to another thread as it is another topic.]

So far, I am very impressed with the support response time! Good job!


@Haloweenhamster, I am planning to add more sensors to the garage door and my front gate.

Your solution is brilliant, coating the internal board, I was about to use silicon on the case itself … but that would have seal it, which is bad coz’ the gas released by the battery, and also the condensation, would have been trapped inside.

I used a Samsung smarthings motion sensor outdoor, under the eave, for almost a year. Still works perfectly. Keep in mind that the weather is mild, and does not freeze in winter.


Please let us know how this goes.

With just coating the board I would worry about the battery and how it will deal with humidity.
I guess I would have gone with waterproofing the case one way or another…

Batteries are well sealed & take a long time to corrode
It’ll be flat long before I’d worry about the corrosion from moisture, sat in water they would corrode a lot quicker but the battery is at the top of the sensor
The sync button is at the bottom so a natural drain for the case

To seal the whole thing would be better but harder to accomplish & you will still have condensation issues from the temperature changes

The easiest & most effective way would be
Along with

But a bit bulky for me

A weatherproof casing would help similar to these https://www.amazon.com/Simplisafe-Entry-Sensor-Weatherproof-Outdoors/dp/B0734LC1HM/ref=sr_1_1?dchild=1&keywords=Sensor+Weatherproof+Case&qid=1591357252&sr=8-1. Though I haven’t tried one yet.


It’s been over a year since your post.
How has your silicon waterproofing trick worked?
Do you have feedback on temp sensitivity?

With the waterproof box you mentioned in the other reply, are you suggesting that condensation would corrode the pcb?

I have 1 sensor on my shed door that works fine without any coating. Its been there for a year and still going. It doesn’t get any direct rain on it but went through a PNW winter last year.

I did modify a motion sensor to work outside and its been out on the side of the house for over a year. It s about 35 feet and 2 walls from my homebase and works every time. It’s used to catch really fast delivery guys so I can see them face on coming onto my porch.

The sensor is in a blink camera case stuffed with pipe wrap. I cut the face out with my dremel tool so the sensor wasn’t partially blocked. Not pretty but it works.

@phi1100 @preset I’ve had a motion and entry sensor outside since last Summer. Both are in areas where they don’t get direct sunlight or rain. They’ve worked as plan throughout the year and trigger selected cameras to record or alarm depending the security setting.

So … I’m PNW… and I want this out in trouble 24/7… would it survive?

Remember children of the corn… Eufy recommends this for batt cam users to increase battery life. I’m guessing that would be outside the protected porch? Rain and trouble?!

@chefrd They’re technically not waterproof, but I got one of each on sale and figured I’d try them outside. They’re definitely doable in the right conditions. Just not sure if they can get wet because of the battery cover.

Although I agree Eufy mentions the motion sensor as an alternative to their cameras…yet NOT make them waterproof, LOL!
