RingMailbox Sensor – White

Love this sensor as it notifies me thru the Ring app when my mailbox has been opened so know right when mail has been delivered. No more going to the mailbox to find nothing there. Also have it set to activate my Ring stick-up cam which is aimed at the mailbox so it records whoever opens the mailbox. My mailbox is about 50 yards from my house & the signal works fine.

I recently purchased and installed the Ring Bridge and Mailbox Sensor and it is working great so far.I don't write reviews often but I wanted to confirm what some others have said that there is no need to install this on the inside lid/door of your mailbox if you have a traditional sized and shaped mailbox.When using the Ring app for setup, it gives you step by step instructions so you don't really need a separate manual. The issue I had with this was that it instructs you to attach the sensor to the inside of the mailbox door and to attach the antennae to the side or even the front of the door. This seemed like a really bad idea to me. I don't want the sensors or cable to get caught when the mail carrier delivers my mail. I also don't want it to be too obvious I have this as someone might decide to take it home with them or to just cause mischief.My metal mailbox already had a hole in the bottom toward the back. I attached the sensor with the included double-sided-adhesive pad and used the included cable guides to make sure the cable did not hover in front of the sensor. I ran the antennae cable through the existing hole and used the other adhesive pad to stick the antennae to the BOTTOM of my mailbox. This will keep it out of the weather and also hides it from casual view.I did test this before using the adhesive pads to make sure this all would work and you probably would want to do the same. My experience was that if I simply open the mailbox door it triggers the motion sensor and I get an alert in the Ring app. This was without even the motion of putting mail or anything into the mailbox. There is a motion sensitivity setting in the app and I have that turned up to max though it may not need to be. It shouldn't hurt anything to leave on max given that motion only occurs when the mailbox door opens anyway.I've included a couple of photos to show my installation. I am not sure why they tell you to put it on the inside lid -- that seems like a bad idea to me. Good luck!

I chose the Ring Mailbox Sensor because it not only had reviews that seemed comparable to other brands, but I also already had some Ring cameras (so no extra apps needed).In short, I've had it installed for about a month now, and while it does seem to quite reliably give me alerts on my phone (via the Ring app), when I tap on the alert to take action, the device often shows up as disconnected/offline. My theory is that it seems the communication to the bridge device is more reliable when initiated by the sensor to the bridge, versus from the bridge to the sensor.A more annoying fact, that I did not discover until after installation and wanted to 'share' it with a family member (just as I do our doorbell), I found that the Mailbox Sensor does not support sharing. So only the account owner gets alerts. (I did vote for this feature to be added on the Ring site for feature modification requests, as many others had the same complaint.)Now for the details.... during installation, the app/instructions ask you to choose if you have a plastic or metal mailbox. Well, I have a cast aluminum mailbox installed within a brick pillar at the road. I chose metal, as it seemed the only difference was whether it recommended using the external antennae or not (I did use it). I also did not want the sensor to be easily visible, adding weight to the door, or reducing the amount of space in my mailbox for packages and such. So I drilled a hole thru the back of the brick pillar (at a carefully measured spot) and into a top back corner of the mailbox, then mounted the sensor (with Gorilla brand heavy duty double-sided tape) into the top back of the mailbox, with the external antennae run thru the hole and mounted flat on the back of the brick pillar (again with heavy duty double-sided tape), facing the house. I mounted the sensor with the word Ring upside down in the box (which does not affect functionality) so I could slide it down (versus up) to remove it from the bracket (which I left attached) to be able to change batteries. (Re: battery life, I used lithium as recommended, and they still report 100% after one month.) I later caulked the hole in the brick with silicone after confirming functionality.I installed the small bridge device in a downstairs window (technically sitting on the inside window sill, as I wanted to keep it mobile for testing until I attached it anywhere with double-sided tape), so it could be as close to direct line of site as possible. The bridge is exactly 69.3' (211"), or 536cm, from the sensor antennae, with nothing but the window and air between them.Overall, I think this sensor is a good step into the mailbox sensor market for Ring, but it could use some improvements, such as the ability to more reliably stay connected/online to the bridge, and the ability to share the device with other Ring users (as you can with Ring doorbells). I've attached some pictures in case anyone else has a brick encased mailbox and are looking for how others have dealt with the situation.Update 8/15/24: Ring just released an app update that allows users to share the Ring Mailbox with other users (such as family members). So that issue has been resolved.Although I still have occasional issues with the sensor (or hub) disconnecting, so I guess 69' must be near the outer limits of its range. I've also had to replace the Energizer Lithium batteries twice since the sensor was first installed (to give an idea of battery life). No change to the Star rating, however, as the occasional disconnects are still annoying enough to take a star off, even though I generally DO like the sensor (especially as I already have other Ring devices).

Not only will you know exactly when someone opened your mailbox, but it also helps you to avoid extra trips to the mailbox if yours isn't right attached to your house. Accurately detects motion of mailbox opening/closing, has an external antenna to help transmit the signal, which also utilizes Amazon sidewalk if you're not too close to your own home Wi-Fi, and acts as a deterrent with the sticker you can put on your mailbox as well. Next will be bundling it with an outdoor camera or motion activated lights pointing at the mailbox...good purchase, which works perfectly as intended.
