LEEPEE Tire Pressure Monitoring System, 5 Alarm Modes, with 4 External Sensors TPMS, Support iOS and Android, Real-time Displays Pressure and Temperature (0.1-6.4Bar)

I contacted LeePee after buying these TPMS valve caps, asking for information on decoding the BLE manufacturer data that they transmit. I was told simply that the company does not provide that information. It was worth a try.That said the decoding information is available for these TPMS units. The hardware works very well, and I see no reason why the company doesn't support users adding value to their product. There are a few Android apps that will monitor the LeePee BLE broadcasts. Since I wanted to log TPMS data and view time graphs I wrote a flutter app that captures and graphs the data. Then I got a little carried away working on an ESP32s3 monitor that provides realtime monitoring, LED alerts, data logging, web graphing. These TPMS monitors will also work with Home Assistant, for integration into your home automation system.I'm using these on my adventure motorcyle. They have held up well during this years travels. Trips over 10,000 miles, climbed Pikes Peak, road along the Atlantic Ocean and the Great Lakes. I live on a pot-holed dirt road, and ride in all types of weather (hot,cold,wet,dry). Battery reports 90% after 6 months of constant broadcasting. The ESP32 has no trouble reading all four caps through my building floors 30 feet from the motorcycles.Other than better support from LeePee, I couldn't ask for anything more.I'm still coding on the ESP32s3. Hoping to add an LVGL graphing option and touchscreen support to my already functional monitoring tool.

This set of BlueTooth pressure monitors seems well made and does just what I needed. I have an older car that came with a tire pressure monitoring system, but after a while the batteries died in the remote wheel-mounted units, and they cost a bundle to replace. My situation is even worse - the car manufacturer went out of Business so even if I bought a new TPMS transmitter I wouldn't be able to get it registered with the car's onboard computer.This kit works with a phone app, so it's pretty universal. Not as convenient as built-in, but still it gives me the data I want. It shows the exact pressure for each tire, so I know which one to top up or check for a leak. The transmitters screw onto the valve stems and they are obvious because they're larger than a normal cap, but not too bad. They have a locking ring to reduce the likelihood of theft - a mixed blessing because they have to be removed to top up the air, so you need to carry around the little wrench to loosen the locking nut. The wrench is the poor quality item in the kit - the metal is soft enough that it distorts when you tighten the nut, enough that it slips when you try to loosen one of the nuts. I found I could squeeze it with a pair of pliers to make it work, but I don't think this is working as designed.Other than the little wrench, everything seems to work as expected and feels solid. You need the wrench every time you want to add air, and also to replace the batteries when they die. In the long run I may need to do something about it. But for now I'm happy with the system.

Have a slow leak in a custom wheel and need to keep an eye on it until the new wheels are available. These air pressure caps are OUTSTANDING!!!! Connect to iPhone using Bluetooth and while they say you have to be within 15 feet of the car, they are regularly connecting when I am in the house. Strongly recommend

They don’t work. The instructions are non sensical unless you read in some form of an Eastern language, which I do not. Not a fan.

It’s easy to install and got paired at first try.The reason I got only 4 stars is because the tires pressure displaying in the app is not accurate, I check the tires pressure before and inflate them to 40 PSI, used on my F150 but the app shows only 36.I can change this review if they get a better and accurate app

I am confused by why some people struggled to get this configured and installed. It was super simple. App is very basic, but does what it is supposed to, tells you the pressure. I installed two sensors on my motorcycle and the other two on the trailer I pull behind my bike. On my upcoming long trip, I plan to check it every day before I leave and when I gas up. Before installing, I filled and manually checked each tire, and the TMPS pressure readings matched EXACTLY. I might let some air out of a tire to see how the low pressure warning works, but so far, it works perfectly. But, I say this product does exactly what it says it does and am very happy so far.

I was excited about the concept of the LEEPEE Tire Pressure Monitoring System. The ability to monitor tire pressure directly from my Android phone is a great convenience, and I was hopeful that this product would be simple to install and use.Unfortunately, despite following all reasonable and appropriate steps for installation, I encountered a critical design flaw that makes the product unreliable and difficult to use safely.During installation, any resistance from the Schrader valve threads causes the internal battery replacement gasket—referred to as the "dismantling gasket"—to detach from the sensor cap. This gasket is keyed to the cap and is essential for both installing and removing the sensor. Once it comes loose, the cap detaches easily, leaving the sensor stuck on the valve while air escapes from the tire.This created a stressful and urgent situation as I struggled to either fully install or safely remove the sensor while air was rapidly leaking. There is no way to reattach the gasket once it detaches, as the back side of the sensor becomes inaccessible once partially installed. Without the cap and gasket in place, it is impossible to remove or tighten the sensor without risking damage.Additionally, one of the sensors I received failed to bind or transmit any data at all, further undermining my confidence in the product.In summary, I made every reasonable effort to install and remove the sensors properly and without damage. However, due to the flawed design and malfunctioning unit, I cannot trust this system and must return it.
