Apologies if this is not the right thread but appeared the most appropriate.

I wanted an app based TPMS and found SensAiry a bit expensive. So I ordered this from AliExpress with external sensors. Total cost - 2264 with shipping for 4 sensors. This is probably the cheapest even on AliExpress for the entire set.

Installed them today and here are some views.

Works through an app called BLE TPMS


Since these are external sensors, they come with an anti-theft mechanism. The hexagonal ring goes in the valve first and the back of the sensor locks into it. The ring is discreet and unless somebody has the screwdriver, its hard to remove without breaking.





The sensor isn't discreet but won't grab a layman's attention. But those who know about TPMS won't find it hard to miss





Installation
External sensors are extremely easy to install. Just remove valve cap, screw the ring and mount the sensors on them. The sensors let air escape while half screwed in. The app's Auto bind feature works (initial binding) only when the air is escaping so the binding has to be done while installing. The other ways to bind are manually inputting codes or scan the barcode that came with it.



The sensor needs to be screwed in while the countdown (60s) is on



I was quite surprised to find the tyre pressure above 36 while I had maintained it at 33 today morning itself at a nearby petrol pump.

Once the sensors are bound, the app begins tracking.

The app takes a while to update after all sensors are tightened


I also tested the app simultaneously on iOS and Android and found iOS noticeably faster in responding and refreshing data.

The funny part, both showed slightly different readings in the end

Now onto external vs internal sensors. Both have its pros and cons.

Pros
1. Easy to install. No alignment/ balancing required.
2. Relatively cheaper to buy and replace individual sensors in the future.

Cons
1. You'll have to remove them when you're refilling the tyres.
2. Theft/ attempt to theft is a concern.

About the app
1. Has a sound + vibration warning system. Show PSI + temperature + sensor battery status.
2. I tried to check the working distance and but the app didn't warn if it is out of range; it just stopped updating.

I had the Sensairy TPMS installed in my Polo GT TSI recently. What I particularly found appealing were

• App based system without the need to screw an aftermarket looking display onto the dash (I do suffer from OCD in maintaining a clutter free OEM look)

• 5th set of sensors for the spare wheel adds to the reassurance factor

However, installation was easier said than done.

• It was tough going from one tyre store to another explaining why I needed their time and equipment.

• Many stores sold their (unbranded) TPMS and ducked out of installing my TPMS, with some large chain stores quoting as high as 3000/- for installation, not far from half the TPMS cost!

• Finally one store recalled having seen such systems in Scorpios and agreed to carry out the installation

Be extremely careful of the tiny screws which can be untraceable if they fall onto the shop floor (Learning from Incidents ). Take full ownership of the parts and take them out one at a time


Involvement from the owner is paramount if you do not want the staff to resort to 'jugaad'


I was clueless on the recommended pressure to be set for the space-saver spare, went with 5 PSI more than regular tyres.


The final display - There is an option to set threshold pressure and temperature values to trigger warnings, my quest is on to find out what they should be


I installed the App on my Android phone as well as my wife's iPhone but have not accessed it simultaneously from both


Noticed a lag (5 to 10 seconds) in capturing data, with some sensors taking longer. A refresh button to hasten auto capture would be welcome, otherwise a neat system that works fine. Support from Sensairy was exemplary - received instant support (email as well as telephone) even on Sunday nights!

Using these exact Same ones since last 4 months.
Do you also get leak warning in winters when the tyres get heated up after a drive and the pressure goes up by 2-3PSi.?

Not frequently. Experienced it twice during a 1400km roadtrip to Udaipur when PSI went from 33 to 38. I maintained 35 at about 20 degrees when I installed these. PSI goes down to 33 when its 10-12 degrees overnight and 37-38 when the tyre heats to 30-32 degrees.

Guys QQ - I am planning to order them soon and i have a query. Lets say I have configured the sensors as per the Manual and instructions.

After Wheel Alignment every 5000 kms, say the front left tyre becomes the right rear tyre. What should be done to make the TPMS system reflect the correct tire. If tyre rotation in done and the rear left tyre leaks, it would show that front left tyre is leaking. What reconfiguration should be done to reflect the correct tyre position after rotation?

Technically there is no risk invlolved, as i would stop the car irrespective of which tyre is leaky and it would take less than 40 seconds to inspect which of the 4 tyres are leaking.

It's the simplest thing to do. All you got to do is to drag and drop the spare tyre with the leaking tyre / new position and it's done. It'll ask you for confirmation.

This is while dragging and dropping.



This is the confirmation before execution.

The spare tyre has been overinflated as it can be deflated to desired pressure before installing.

[sudev]

Not good idea to keep spare so much over inflated. Couple of PSI is okay

Inspired by BoneCollector sir's installation of the TPMS, I went ahead and purchased the same for my Creta. Got the installation done and up and running. Link to the installation and all images

The only link pending in this installation was Android Auto integration. Finally got it today. Here are more details on the integration

Great. I've not yet checked due to some work. I'll be doing it tomorrow. So basically if you're looking at pressures, you cannot navigate. Can music be streamed from any of the Android Auto apps like Amazon Prime Music while the screen displays the pressures?

I could change screens from SensAiry to Maps and then to music also.

Only issue is the HU is useless and laggy. Takes ages for things to get displayed.

Folks

I was seriously considering this as I am not very happy with my Nonda Zus external TPMS.

The key reasons were that it is Indian and the responsiveness that BoneCollector stressed on. Also the fact that it is app based.

But there was no response to my mail inquiring about the product. I got the sales persons number from a contact on WhatsApp. Looks like the sales person has quit. The phone was answered by a 'technical guy'.

How stable is this company? Will it still be there 6 months from now?

Any info?

BTW, they said the 2 wheeler system is not functional and that they offer a 500 buck discount for t-bhp members. They also offer a 4 valve system for 1500 less.

I got 4 Sensairy sensors installed in my Hexa, was unable to test it much as I left for a work assignment couple days after the installation.

The sensors were installed at a tyre shop in Thane, shop recommend by the Sensairy guys.
It took a little more than an hour and they charged
me Rs.100 per tyre plus Rs. 550 for wheel balancing, total 950 which I believe is pretty reasonable.

Just after installation I faced a little issue and messaged Mr. Prabhu, his response was instantaneous, fortunately the issue got rectifed on it's own.

Don't know how the company is doing but their product is good and customer service exemplary, I hope with such strong fundamentals they will last for a while.

If you check online their website has phone number and email id for queries.

I don't think there are issues with the stability related for the company. I am in constant touch with Mr. Prabhu over WhatsApp for any doubts or help needed on the TPMS system. I get timely response too.

Did you try talking to him (Mr. Prabhu I mean)?

Got sensairy TPMS installed for my Hexa as soon as I got my car in January. What is exceptional is the brilliant service they offer. Two engineers from the development team helped me install the sensors. This really inspired confidence in the company and the proactive nature of Mr.Prabhu to answer all the queries instantly, is what today's customers demand.

[sridhu]

I got the Sensairy TPMS installed.

Happy until now. Good support from Prabhu.

My installation review of the Sensairy is included in my Crysta Ownership post
